2010s Mass Shootings In The United States

"It’s problematic. It is fundamentally problematic to have that level of weaponry in a civilian environment, unregulated. It is problematic. It was modified in essence to function as a rifle, and to avoid any legal prohibitions."

"Of the many makes on the US market, one stands apart: the Glock. Gun-control activists have denounced the Austrian pistol and tried to have it banned—attacks that only enhanced the Glock’s glamour in the eyes of its fans. Today the Glock is on the hip of more American police officers than any other handgun. It is all over the television news and the Internet. When American soldiers hauled Saddam Hussein from his underground hideout in 2003, the deposed Iraqi ruler came to the surface with a Glock. New York Giants star wide receiver Plaxico Burress shot himself in the leg in 2009 with a Glock he had stuck in his waistband before heading to a Manhattan nightclub. Some of our most prolific psychopaths have favored the Glock, presumably because of its large ammunition capacity and lightning speed. Seung-Hui Cho, who murdered thirty-two people at Virginia Tech in 2007, used a Glock. So did Steven Kazmierczak when he shot twenty-one, killing five, at Northern Illinois University in 2008. Jared Loughner fired a Glock with a thirty-three-round magazine in his January 2011 attempt to assassinate Representative Gabrielle Giffords in Tucson, Arizona, an attack that resulted in six dead and thirteen injured, including Giffords, who survived after a nine-millimeter round passed entirely through her brain."

"When Omar Mateen burst into Pulse nightclub in Orlando on June 12 and opened fire on the crowd, killing 49 people and wounding 53 others, he was armed with two guns. But in the aftermath of the attack, only one of the weapons became the subject of intense scrutiny. Most of the attention has focused on Mateen's semi-automatic .223-caliber Sig Sauer MCX, which is modeled after the AR-15 assault rifle. The fact that similar weapons were used during several recent mass shootings — including the 2012 massacre at Sandy Hook Elementary School in Connecticut, the movie theater rampage in Aurora, Colorado that same year, and the 2015 attack in San Bernardino, California — led to a renewed push for an assault weapons ban, and prompted many reports about how easily AR-15s can be purchased in Florida. But Mateen was also carrying a Glock, a brand of firearm that has been used nearly as often as assault rifles to commit mass murder. A list of mass shootings between April 1999 and January 2013 prepared for lawmakers in Connecticut showed that rifles were used in 10 incidents and shotguns in 10 others, while handguns were used in 42. Glock brand pistols turned up in nine of those cases. Another compendium of mass shootings since 2009 by the New York Times showed that handguns were used in 13 incidents, compared to five in which a rifle was the primary weapon. Glocks were recovered from six of the perpetrators.... The earliest known case of a Glock being used in a mass shooting came in 1991, when unemployed merchant mariner George Jo Hennard drove his pick-up truck through the plate-glass window of Luby's Cafeteria in Killeen, Texas. Hennard exited his vehicle and methodically fired two pistols, including a Glock 17, at restaurant patrons, killing 24 and injuring 27. In the last nine years, Glocks have figured prominently in at least five mass shootings. In 2007, Seung-Hui Cho, a senior at Virginia Tech University, used a Glock 19 and Walther P22 to kill 32 people and wound 17 others in two separate attacks on campus. The Glock 19 is a smaller pistol that is easier to conceal. Three years later, Jared Lee Loughner used a Glock 19 to shoot 20 people in Arizona, gravely wounding US Representative Gabrielle Giffords and killing six others, including a nine-year-old girl. In 2013, Pedro Vargas went on a shooting rampage inside his apartment complex in Hialeah, Florida. With his Glock 17, Vargas murdered six people and held two neighbors hostage during an eight-hour stand-off until a SWAT team stormed the building and killed him."

"Talk about a killer gimmick. An Arizona Republican fundraiser is offering as a prize the same type of gun used in the attempted assassination of Arizona Congresswoman Gabrielle Giffords. On August 26 the Pima County Republican Party sent out its regular online newsletter. It contained your standard newsletterisms - an intro from the chairman, a description of local candidates, a calendar of upcoming events, and so on. But this particular issue also featured an eye-catching giveaway to raise money for GOTV (Get Out the Vote) efforts. For just $10, readers can purchase a raffle ticket (out of 125 offered) for a chance to win a brand new handgun. Not just any handgun, but a Glock 23. Arizona Republicans surely know just how effective this particular brand of gun can be. After all, it was only eight months ago that Jared Lee Loughner used a Glock 19 in Tucson - the seat of Pima County - to shoot Congresswoman Gabrielle Giffords in the head. Giffords survived, but six other people, including a nine year old girl and a federal judge, were killed in the same shooting."

"A store selling firearms is required to check with NICS before making a sale. In Mr. Loughner’s case, when the 22-year-old went to the Sportsman’s Warehouse outlet in Tucson, Ariz., on Nov. 30 to purchase a Glock 19 semiautomatic handgun, a background check was performed and he came up clear, according to the store manager. That Glock was used in Saturday’s rampage in Tucson that killed six people and injured 13 others, including the critically wounded Rep. Gabrielle Giffords (D) of Arizona. Arizona, well known for its low barriers to gun possession, also prohibits the possession of firearms by anyone found to “constitute a danger to himself or others” and whose right to possess a firearm has not been restored under the requirements laid out by state law."

"With its large ammunition capacity, quick reloading, light trigger pull, and utter reliability, the Glock was hugely innovative — and an instant hit with police and civilians alike. Headquartered in Deutsch-Wagram, Austria, the company says it now commands 65 per cent of the American law enforcement market. The Toronto and Durham police forces are also all-Glock, with Toronto’s emergency task force equipped with the same gun Loughner is alleged to have used. With all those customers and that visibility, it’s no surprise that the Glock has also been the gun of choice for some prolific psychopaths. Byran Uyesugi used a Glock 17 to kill seven people at a Xerox office in Honolulu in 1999. Seung-Hui Cho, who murdered 32 at Virginia Tech in 2007 before killing himself, used the same Glock 19 model that Loughner is accused of firing in Tucson. Steven Kazmierczak packed a Glock 17 when he shot 21 people, killing five, at Northern Illinois University in 2008. The smooth-firing Glock did not cause these massacres any more than it holds up convenience stores. But when outfitted with an extra-large magazine, it can raise the body count. The shooters in Arizona, Illinois, Virginia, Hawaii, and Texas could not have inflicted so many casualties so quickly had they been armed with old-fashioned revolvers. In its 2010 catalog, the manufacturer boasts that while the Glock 19 is “comparable in size and weight to the small .38 revolvers it has replaced,” the pistol “is significantly more powerful with greater firepower and is much easier to shoot fast and true.” The Tucson gunman demonstrated those qualities all too vividly. Loughner is said to have emptied his 33-round clip in a minute or two, a feat requiring no special skill."

"JAN. 8, 2011 Jared L. Loughner, 22, killed six people with a Glock handgun in a supermarket parking lot in Tucson, Ariz., at an event for Gabrielle Giffords, who was a Democratic representative from Arizona. 2007 Mr. Loughner was arrested for possession of drug paraphernalia, but the charges were dropped. The next year, he failed a drug test when trying to enlist in the Army. Neither incident barred him from buying a gun. OCT. 2010 He was forced to withdraw from community college because of campus officials’ fears about the safety of the staff and students, his parents later said. The incident would not have shown up on a background check. NOV. 30, 2010 He passed a background check and bought the handgun at a store in Tucson, Ariz. JAN. 8, 2011 He killed six people in Tucson."

"Shooting: Gabrielle Giffords constituent meeting in a Tucson, Arizona, parking lot Date: Jan. 8, 2011 Perpetrator: Jared Lee Loughner Gun: Glock 19 9 mm semiautomatic handgun. Loughner killed six people and shot 13 more, including Rep. Giffords. How he got it: Arizona, which has some of the laxest gun laws in the country, passed a law in 2010 that allowed people to buy guns for concealed carry without a permit. Though guns cannot be sold to people with severe mental illness and though Loughner was suspended from his community college for mental health issues, no court had ever declared him mentally unfit, so his on-the-spot background check at a gun outlet came up clear."

"Virginia Tech. Gabby Giffords. Now Aurora, Colo. The names and places are linked by tragedy, death and the Glock semiautomatic handgun. The young men who carried out these mass shootings — and analysis says such killers are almost always male and most often young — all counted at least one of these versatile, easy-to-fire pistols in their arsenals.... Like other mass shootings, Friday’s attack sparked calls for more gun control."

"Arizona Republicans are fundraising by raffling off a Glock pistol, the same brand of gun used to shoot Rep. Gabrielle Giffords just eight months ago."

"The sickening shooting spree in Tucson holds many lessons for our country, but the most important is this: It's much too easy for dangerous people to get their hands on deadly weapons. We must change this. A good start is by banning high-capacity gun magazines -- which allow scores of bullets to be loaded at one time -- such as the one used in the Tucson massacre that left six people dead and 14 others wounded, including my colleague, Rep. Gabrielle Giffords. According to news reports, Jared Lee Loughner, the alleged shooter in Tucson, used a 33-round magazine in a murderous rampage. The sheriff says 31 spent rounds were found on the scene. As we now know, a group of heroic bystanders stopped the shooter by wrestling him to the ground. But they didn't have an opportunity to intervene until he emptied the magazine and paused to reload. If the shooter didn't have access to the high-capacity magazine that he used, he would have stopped to reload sooner and lives might have been saved. Loughner's magazine was attached to a 9 mm Glock 19 semi-automatic handgun, which is the preferred weapon of deranged madmen. In 2007, Seung-Hui Cho used the same model in the Virginia Tech shooting spree, which claimed 32 lives."

"The Glock 19 Jared Lee Loughner allegedly used to try to assassinate Rep. Gabrielle Giffords is a popular firearm around the world.... Kristen Rand, legislative director of the Violence Policy Center, ...said the Glock 19 has been used in other mass killings, including the Virginia Tech shooting in April 2007. In that incident, Seung-Hui Cho used a Glock 19 and a Walther P22 rifle to kill 32 students and take his own life.... Loughner was allegedly able to fire at least 20 rounds from his 33-round clip, according to [Paul] Helmke [president of the Brady Campaign to Prevent Gun Violence]."

"The investigators believe that Loughner, 22, did not have sufficient income of his own to buy the Glock 19 semiautomatic handgun, the four magazines and the knife he allegedly carried to the event in front of a Tucson supermarket, the sources said. They estimated the cost at close to $1,000. Two of the magazines were extended ones capable of holding up to 33 rounds."

"The high-capacity Glock pistol owned by Norway mass murderer Anders Behring Breivik stands as a stark example of the gun industry’s marketing of increased lethality. Since the mid-1980s, increased firepower and capacity have defined the products of the gun industry—of both U.S. and foreign manufacture. Glock pistols have been part of the arsenals of the some of the most infamous mass shooters in the United States, including the 2007 Virginia Tech shooting which left 33 dead and 17 wounded and, more recently, the attack in January 2011 in Tucson, AZ, by Jared Loughner which left six dead and 13 wounded—including U.S. Representative Gabrielle Giffords (D-AZ). Oklahoma City bomber Timothy McVeigh was illegally carrying a 45 caliber Glock pistol when he was stopped by law enforcement after the 1995 bombing for driving a car without a license plate."

"Examples of Mass Shootings in the United States Involving Glock Pistols Mass Shooting Incident Safeway parking lot Tucson, Arizona January 8, 2011 Shooter: Jared Loughner Casualties 6 dead, 13 wounded Firearm(s) Glock 19 pistol"

"Enhanced lethality, that's what we are talking about. Lethality increases when you have larger bullets, more ammunition and the guns are easier to operate. That's the contribution Glock and others have brought to America."

"Sales of Glocks rose in the immediate aftermath of Giffords’s shooting."

"The Glock pistol reportedly used by alleged South Carolina mass killer Dylann Roof stands as a stark example of the gun industry’s marketing of increased lethality. Since the mid-1980s, increased firepower and capacity have defined the products of the gun industry — of both U.S. and foreign manufacture. Glock pistols have been part of the arsenals of some of the most infamous mass shooters in the United States, including the 2007 Virginia Tech shooting, which left 33 dead and 17 wounded, as well as the January 2011 attack at a Tucson, Arizona Safeway parking lot by Jared Loughner which left six dead and 13 wounded — including then-U.S. Representative Gabrielle Giffords. Examples of additional mass shootings involving Glock pistols include: * The 2012 attack at a Sikh Temple in Oak Creek, Wisconsin that left seven dead (including the shooter). * The 2012 mass shooting at the Century Aurora 16 movie theater that left 12 dead. * A 1999 shooting at a Xerox Office Building in Honolulu, Hawaii, that left seven dead. * A 1999 shooting in Springfield, Oregon, where the 15-year-old shooter killed his parents, and then went to school where he killed two of his classmates. * A 1998 workplace shooting at the Connecticut State Lottery Headquarters where the shooter killed four before taking his own life. * The 1991 shooting at Luby’s Cafeteria in Killeen, Texas that left 24 dead (including the shooter)."

"When Jared Lee Loughner went to the Sportsman's Warehouse outlet on Nov. 30, he faced few obstacles to walking away with a Glock 19 semiautomatic handgun. Loughner was making the purchase in Arizona, a state with an Old West culture where gun laws are among the most lenient in the United States. The 22-year-old passed an instant background check required under federal law for all gun buyers, said Reese Widmer, manager of the Tucson store. A law enacted last year allowed Loughner to conceal and carry the pistol without a permit. On Sunday, Loughner was charged with using the Glock in the Tucson rampage that gravely wounded Rep. Gabrielle Giffords (D-Ariz.) and killed six others, including a federal judge and a 9-year-old girl. In all, 20 people were shot in the attack."

"Investigators say that on Nov. 30, Jared L. Loughner went to a Sportsman’s Warehouse in Tucson, Ariz., and bought a Glock 19, which sells for roughly $500. He is accused of using it during a rampage on Jan. 8 that left 6 people dead and 13 wounded, including Representative Gabrielle Giffords, Democrat of Arizona, who also owns a Glock.... The guns are popular with law enforcement, consumers and, apparently, some young men intent on massacre. Seung-Hui Cho, who killed 32 at Virginia Tech University in 2007, and Steven Kazmierczak, who killed five at Northern Illinois University in 2008, were armed with Glocks."

"What they have spent less time discussing are the tools that allowed Loughner to allegedly carry out the attack - the high powered weapon and ammunition that helped him do so much damage so quickly. Arizona has some of the laxest gun laws in the nation, laws that allowed Loughner to purchase and carry a Glock 19 9mm semi-automatic pistol - and high-capacity clips - despite the fact that he was barred from his community college campus because administrators saw him as a mentally-unstable security threat...The clip allegedly used by Loughner, which allows for 33 shots without reloading instead of about 10 in a normal clip, would have been illegal under the assault weapons ban that Congress let expire in 2004."

"It’s important to understand how we got where we are today. In 1966, the unthinkable happened: a madman climbed the University of Texas clock tower and opened fire, killing more than a dozen people. It was the first mass shooting in the age of television, and it left a real impression on the country. It was the kind of terror we didn’t expect to ever see again. But around 30 years ago, we started to see an uptick in these types of shootings, and over the last decade they’ve become the new norm. In July 2012, a gunman walked into a darkened theater in Aurora and shot 12 people to death, injuring 70 more. One of his weapons was an assault rifle. The sudden and utterly random violence was a terrifying sign of what was to come. In December 2012, a young man entered an elementary school in Newtown and murdered six educators and 20 young children. One of his weapons was an assault rifle. Watching the aftermath of these young babies being gunned down was heartrending. In June 2016, a gunman entered a nightclub in Orlando and sprayed revelers with gunfire. The shooter fired hundreds of rounds, many in close proximity, and killed 49. Many of the victims were shot in the head at close range. One of his weapons was an assault rifle. Last month, a gunman opened fire on concertgoers in Las Vegas, turning an evening of music into a killing field. All told, the shooter used multiple assault rifles fitted with bump-fire stocks to kill 58 people. The concert venue looked like a warzone. Over the weekend in Sutherland Springs, 26 were killed by a gunman with an assault rifle. The dead ranged from 17 months old to 77 years. No one is spared with these weapons of war. When so many rounds are fired so quickly, no one is spared. Another community devastated and dozens of families left to pick up the pieces. These are just a few of the many communities we talk about in hushed tones—San Bernardino, Littleton, Aurora, towns and cities across the country that have been permanently scarred."

"Devin Patrick Kelley, the former US air force serviceman who killed at least 26 people and injured another 20 in a Texas church this past Sunday morning, had been court-martialed in 2012 for assaulting his wife and stepson. He was able to purchase his murder weapons even though, since 1996, federal law has banned people with domestic violence convictions from owning guns."

"The mass murder last week at the Pittsburgh Synagogue has something in common with the deadliest massacres: the AR-15 semi-automatic rifle. Variations of the AR-15 were used to kill at a Texas church, a Las Vegas concert, Marjorie Stoneman Douglas High School in Florida and Sandy Hook Elementary School. The AR-15 style rifle is the most popular rifle in America. There are well over 11 million, and they are rarely used in crime. Handguns kill far more people, but the AR-15 is the choice of our worst mass murderers. AR-15 ammunition travels up to three times the speed of sound."

"A Pittsburgh synagogue, a Florida high school, a Texas church, a Las Vegas concert, a Connecticut elementary school. These are the locations of some of the deadliest mass shootings in America in recent history, and they all have something in common: The style of weapon used at each horrific scene was the AR-15 semiautomatic rifle."

"...a bomb went off on the inside. And our job is to go in there and clean it up....At some point it's like putting Humpty Dumpty back together again...his organs are now in different pieces and you have to reconstruct them. The arm was missing soft tissue, skin, muscle and part of the nerves were damaged. The bowel has to be put back together some of the areas of injury has to heal itself so you can see that he can walk around like a normal child and behave as normal as possible."

"Compared with pistols, assault rifles are used rarely in shootings. According to F.B.I. statistics, 374 people were murdered with any kind of rifle in 2016; 7,105 were killed by a handgun. But the AR-15 has been a recurring character in some of America’s most infamous violent crimes. Adam Lanza used his to kill 20 children and six educators at Sandy Hook. Stephen Paddock used an enhanced AR-style gun to kill 58 concertgoers and wound hundreds on the Las Vegas Strip in October. A month later, Devin Kelley murdered 26 congregants with a Ruger AR-15 variant at a church in Sutherland Springs, Tex. And the rampage last month at Marjory Stoneman Douglas High School in Parkland, Fla., renewed calls for assault-style rifles to be banned — a common refrain after mass shootings."

"AR-15-style rifles have become something of a weapon of choice for mass shooters. One was used last year to kill 26 people during Sunday morning church services in Sutherland Springs, Texas, and it was among the stockpile of firearms used a month earlier to kill 58 concertgoers in Las Vegas. AR-15-style rifles were also used at the shootings at Pulse nightclub in Orlando, Florida; at an employee training in San Bernardino, California, and at Sandy Hook Elementary School in Newtown, Connecticut."

"AR-15 style rifles have been the weapon of choice in many recent mass shootings, including the Texas church shooting Sunday, the Las Vegas concert last month, the Orlando nightclub last year and Sandy Hook Elementary School in 2012. Here is a list of mass shootings in the U.S. that featured AR-15-style rifles during the last 35 years, courtesy of the Stanford Geospatial Center and Stanford Libraries and USA TODAY research: Feb. 24, 1984: Tyrone Mitchell, 28, used an AR-15, a Stoeger 12-gauge shotgun and a Winchester 12-gauge shotgun to kill two and wound 12 at 49th Street Elementary School in Los Angeles before killing himself. Oct. 7, 2007: Tyler Peterson, 20, used an AR-15 to kill six and injure one at an apartment in Crandon, Wis., before killing himself. June 20, 2012: James Eagan Holmes, 24, used an AR-15-style .223-caliber Smith and Wesson rifle with a 100-round magazine, a 12-gauge Remington shotgun and two .40-caliber Glock semi-automatic pistols to kill 12 and injure 58 at a movie theater in Aurora, Colo. Dec. 14, 2012: Adam Lanza, 20, used an AR-15-style rifle, a .223-caliber Bushmaster, to kill 27 people — his mother, 20 students and six teachers — in Newtown, Conn., before killing himself. June 7, 2013: John Zawahri, 23, used an AR-15-style .223-caliber rifle and a .44-caliber Remington revolver to kill five and injure three at a home in Santa Monica, Calif., before he was killed. March 19, 2015: Justin Fowler, 24, used an AR-15 to kill one and injure two on a street in Little Water, N.M., before he was killed. May 31, 2015: Jeffrey Scott Pitts, 36, used an AR-15 and .45-caliber handgun to kill two and injure two at a store in Conyers, Ga., before he was killed. Oct. 31, 2015: Noah Jacob Harpham, 33, used an AR-15, a .357-caliber revolver and a 9mm semi-automatic pistol to kill three on a street in Colorado Springs, Colo., before he was killed. Dec. 2, 2015: Syed Rizwyan Farook and Tashfeen Malik, 28 and 27, used two AR-15-style, .223-caliber Remington rifles and two 9 mm handguns to kill 14 and injure 21 at his workplace in San Bernardino, Calif., before they were killed. June 12, 2016: Omar Mateen, 29, used an AR-15 style rifle (a Sig Sauer MCX), and a 9mm Glock semi-automatic pistol to kill 49 people and injure 50 at an Orlando nightclub before he was killed. Oct. 1, 2017: Stephen Paddock, 64, used a stockpile of guns including an AR-15 to kill 58 people and injure hundreds at a music festival in Las Vegas before he killed himself. Nov. 5, 2017: Devin Kelley, 26, used an AR-15 style Ruger rifle to kill 26 people at a church in Sutherland Springs, Texas, before he was killed. Feb. 14, 2018: Police say Nikolas Cruz, 19, used an AR-15-style rifle to kill at least 17 people at Marjory Stoneman Douglas High School in Parkland, Fla."

"Americans who know nothing else about firearms are all too familiar with the name AR-15. It’s the semi-automatic weapon that murderers have used in many of the most notorious and highest-casualty gun killings of recent years: Aurora, Colorado. Newtown, Connecticut. Orlando, Florida. San Bernardino, California. Now, with modified versions, in Las Vegas, Nevada, and Sutherland Springs, Texas...A little bullet pays off so much in wound ballistics. That is what people who choose these weapons know."

"Because an AR-15, or a variant, was reportedly used in several mass shootings — including Aurora, Colorado; Newtown, Connecticut; San Bernardino,California; Sutherland Springs, Texas; Las Vegas and Parkland, Florida, in which a total of 154 people were killed — this civilian sibling of a military assault rifle is an exceptionally polarizing product of modern American industry. The AR-15 and its semiautomatic cousins — they shoot one round for each pull of the trigger ─ incite repulsion among those who see them as excessive, grotesque and having no place on the civilian market. It is the focus of multiple attempts at prohibition, which in turn has prompted people to run out and buy more. Such “panic buying” drove sales of AR-15s to record levels during the presidency of Barack Obama and the 2016 presidential campaign."

"An AR-15 once again made an appearance at a mass shooting, this time at a Parkland, Fla., high school on Wednesday...These AR-style rifles have appeared in some of the deadliest shootings in the last few years, including a concert in Las Vegas, a nightclub in Orlando, a church in Texas and an elementary school in Newtown, Conn."

"Parkland, Florida. Las Vegas, Nevada. Sutherland Springs, Texas. Now, Pittsburgh, Pennsylvania. Recent deadly mass shootings in these US cities have at least one thing in common: the AR-15.... This weapon has become increasingly popular in the US, especially since the 1994 federal weapons ban expired in 2004, and has been used in many other mass shootings around the country. Not just the three listed above. To understand how and why this has happened, we put together a historical overview of the weapon and spoke with David Chipman, a senior policy analyst at Giffords and former special agent with the Bureau of Alcohol, Tobacco, Firearms, and Explosives.... Chipman said that he believes AR-15s have been so frequently used in mass shootings for two reasons: popularity and lethality. "It's a two-fold thing: the AR-15 is like the 4-door sedan of assault rifles," Chipman said. "It was America's weapon ... there's an Americana aspect." But so many mass shootings become mass shootings "because the AR-15 was used," he said, adding that the damage the weapon does to the human body pales in comparison to a handgun. "I've talked to ER physicians," Chipman said. "Rifle rounds are so devastating to the human body.""

"Six of the 10 deadliest mass shootings in the U.S. over the past decade have used an AR-15-style semi-automatic rifle. The latest instance was Wednesday’s high school shooting in Parkland, Florida, which left 17 dead and 14 others injured. The gun used in the shooting was a Smith and Wesson M&P AR-15, federal law enforcement officials told the Associated Press. The same model weapon was used in previous mass shootings, including the Aurora, Colo., movie theater shooting that claimed 12 lives and the rampage in San Bernardino, Calif., that claimed 14. These rifles and other versions of the AR-15 are the civilian equivalent of fully-automatic M16 rifles used by the U.S. military since the Vietnam War. They are fancied by gun owners because they are typically easy to purchase — often for less than $1,000 — and can be customized with a number of accessories, such as bump stocks, which essentially convert the semi-automatic weapons into fully-automatics. A bump stock was deployed by the assailant in the 2017 Las Vegas shooting, which left 58 dead, making it the deadliest mass shooting in modern American history. Up until that point, the country’s deadliest mass shooting had occurred just a year prior at the Pulse nightclub in Orlando, where the perpetrator used an SIG MCX semi-automatic rifle — highly similar to AR-15s in aesthetic and purpose — to kill 49 people. Comparable weapons were also used at Sandy Hook Elementary School (27 dead) and a Sutherland Springs, Texas, church (25 dead). The high number of fatalities in these incidents highlight how AR-15-style guns, much like their M16 cousin, are capable of inflicting serious damage to a number of people at once. “For practical purposes, for the person that’s just tuning in, the non-gun owner, it’s a very similar type of firearm,” Rob Pincus, who has made a career out of training armed professionals, told TIME."

"Newtown. San Bernardino. Las Vegas. Sutherland Springs. And now, Parkland. Five of the six deadliest mass shootings of the past six years in the United States. In each of them, the gunman had an AR-15-style semiautomatic rifle."

"NOV. 5, 2017 A gunman identified as Devin Patrick Kelley, 26, opened fire at a Sunday service in a rural Texas church, killing at least 26 people. The authorities said Mr. Kelley used a Ruger AR-15 variant, a knockoff of the standard service rifle carried by the American military. 2012 Mr. Kelley, who was in the Air Force, was convicted of assaulting his wife and breaking his infant stepson’s skull. An airman first class, he was sentenced to 12 months’ confinement and a reduction to the lowest possible rank, E-1. 2014 Mr. Kelley received a “bad conduct” discharge from the Air Force. 2016 - 2017 Mr. Kelley purchased two firearms — one in 2016 and one in 2017 — from two Academy Sports & Outdoors stores in San Antonio. He passed a federal background check in both cases, according to a statement released by the store. NOV. 5, 2017 Twenty-six people were killed and at least 20 more were wounded at the church shooting in Sutherland Springs. Mr. Kelley was later found dead in his vehicle. The police recovered two additional handguns from the car. NOV. 6, 2017 The Air Force admitted that it had failed to enter Mr. Kelley’s domestic violence conviction into federal databases, which could have blocked him from buying the rifle he used in the massacre."

"As officials continue to investigate 19-year-old Nikolas Cruz, who is accused of opening fire on his former high school Wednesday afternoon, killing at least 17 people and injuring more than a dozen others, familiar details are already emerging about the weapon police believe was used in the massacre. Police suspect Cruz was armed with at least one AR-15-style rifle and “countless magazines” in the deadly shooting at Marjory Stoneman Douglas High School in Parkland, Florida. This adds to a disturbing trend. In many of the most deadly mass shootings in the last several years, including the Las Vegas massacre on Oct. 1 and the shooting at a Texas church on Nov. 5, the lone gunmen were armed with assault-style rifles like the one reportedly used at the Florida school."

"This country has no monopoly on troubled young men. We have no monopoly on hate groups. We aren’t the only place where people miss signs of danger in troubled young men. What distinguishes the United States from the developed world is our open market in the weaponry of war — in weapons whose chief purpose and selling point is their obscene ability to kill as many people as possible in the shortest burst of time. Is it any surprise that the weapon used in this week’s carnage was the same style of semiautomatic assault rifle that was used with deadly efficiency at a concert in Las Vegas, a Texas church, an Orlando nightclub, a Connecticut elementary school? These weapons designed for combat, accompanied by multiple ammunition magazines, have become the weapons of choice for mass shooters. It is time for a national ban on their sale and possession. Now, before the next set of parents face the unimaginable agony of the phone call that never gets answered."

"The nation's mass-shooting problem seems to be getting worse. And the latest, most serious shootings all seem to have one new thing in common: the AR-15 semi-automatic assault rifle. The AR-15 typically has large magazines, shoots rounds at higher velocities than handguns, and leaves more complex wounds in victims. In each one of the older shootings on the 10-deadliest list — including the 2007 attack on Virginia Tech in Blacksburg, Va., that left 32 victims dead — the shooters carried handguns. (The exception is the 1984 San Ysidro massacre, where the gunman also used a shotgun and an Uzi semiautomatic carbine.) But in all of the latest incidents — Newtown, Conn., in 2012; San Bernardino, Calif., in 2015; Orlando, Fla., in 2016; Las Vegas, 2017; Sutherland Springs, Texas, 2017 — the attackers primarily used AR-15 semiautomatic rifles. There are a couple of theories that might suggest why AR-15s would be associated with deadlier attacks. AR-15 rifles shoot small but high-velocity .223-caliber rounds that often shatter inside victims' bodies, creating more devastating injuries than the wounds typically left by larger but lower-velocity handgun rounds. Shooters also commonly use the rifles with 30-round magazines, which allow them to fire more rounds uninterrupted, compared with the smaller magazines commonly used in handguns."

"Parkland, Florida. Las Vegas, Nevada. Sutherland Springs, Texas. Now, Pittsburgh, Pennsylvania. Recent deadly mass shootings in these US cities have at least one thing in common: the AR-15.... This weapon has become increasingly popular in the US, especially since the 1994 federal weapons ban expired in 2004, and has been used in many other mass shootings around the country. Not just the three listed above. To understand how and why this has happened, we put together a historical overview of the weapon and spoke with David Chipman, a senior policy analyst at Giffords and former special agent with the Bureau of Alcohol, Tobacco, Firearms, and Explosives.... Chipman said that he believes AR-15s have been so frequently used in mass shootings for two reasons: popularity and lethality. "It's a two-fold thing: the AR-15 is like the 4-door sedan of assault rifles," Chipman said. "It was America's weapon ... there's an Americana aspect." But so many mass shootings become mass shootings "because the AR-15 was used," he said, adding that the damage the weapon does to the human body pales in comparison to a handgun. "I've talked to ER physicians," Chipman said. "Rifle rounds are so devastating to the human body.""

"OCT. 1, 2017 Fifty-eight people were killed and more than 500 were wounded when Stephen Paddock, from a perch high in a hotel, opened fire onto a crowd of concertgoers at an outdoor music festival in Las Vegas. Authorities recovered an arsenal of weapons — at least 23 from his hotel room — including AR-15-style rifles. SINCE 1982 Mr. Paddock started buying firearms in 1982, said Jill Snyder, a special agent in charge at the Bureau of Alcohol, Tobacco, Firearms and Explosives. WITHIN A YEAR OF THE SHOOTING Mr. Paddock legally purchased 33 firearms from Oct. 2016 to Sept. 2017, Ms. Snyder said. Most of those guns were rifles. Such purchases do not prompt reports to the bureau because there is no federal law requiring a seller to alert the bureau when a person buys multiple rifles. OCT. 1 Fifty-eight people were killed when Mr. Paddock fired onto the crowd of more than 22,000 from his hotel room at the Mandalay Bay Resort and Casino in Las Vegas. He used at least one semiautomatic rifle modified to fire like an automatic weapon by attaching a “bump stock,” not shown above. AFTER THE SHOOTING Authorities retrieved 47 guns from the hotel room and Mr. Paddock’s homes in Mesquite and Verdi, Nev. The bureau found Mr. Paddock purchased most of the guns in Nevada, Utah, California and Texas. Twelve of the rifles recovered from the hotel were each outfitted with a bump stock."

"Compared with pistols, assault rifles are used rarely in shootings. According to F.B.I. statistics, 374 people were murdered with any kind of rifle in 2016; 7,105 were killed by a handgun. But the AR-15 has been a recurring character in some of America’s most infamous violent crimes. Adam Lanza used his to kill 20 children and six educators at Sandy Hook. Stephen Paddock used an enhanced AR-style gun to kill 58 concertgoers and wound hundreds on the Las Vegas Strip in October. A month later, Devin Kelley murdered 26 congregants with a Ruger AR-15 variant at a church in Sutherland Springs, Tex. And the rampage last month at Marjory Stoneman Douglas High School in Parkland, Fla., renewed calls for assault-style rifles to be banned — a common refrain after mass shootings."

"A Pittsburgh synagogue, a Florida high school, a Texas church, a Las Vegas concert, a Connecticut elementary school. These are the locations of some of the deadliest mass shootings in America in recent history, and they all have something in common: The style of weapon used at each horrific scene was the AR-15 semiautomatic rifle."

"AR-15-style rifles have become something of a weapon of choice for mass shooters. One was used last year to kill 26 people during Sunday morning church services in Sutherland Springs, Texas, and it was among the stockpile of firearms used a month earlier to kill 58 concertgoers in Las Vegas. AR-15-style rifles were also used at the shootings at Pulse nightclub in Orlando, Florida; at an employee training in San Bernardino, California, and at Sandy Hook Elementary School in Newtown, Connecticut."

"This country has no monopoly on troubled young men. We have no monopoly on hate groups. We aren’t the only place where people miss signs of danger in troubled young men. What distinguishes the United States from the developed world is our open market in the weaponry of war — in weapons whose chief purpose and selling point is their obscene ability to kill as many people as possible in the shortest burst of time. Is it any surprise that the weapon used in this week’s carnage was the same style of semiautomatic assault rifle that was used with deadly efficiency at a concert in Las Vegas, a Texas church, an Orlando nightclub, a Connecticut elementary school? These weapons designed for combat, accompanied by multiple ammunition magazines, have become the weapons of choice for mass shooters. It is time for a national ban on their sale and possession. Now, before the next set of parents face the unimaginable agony of the phone call that never gets answered."

"A document, recently released—“LVMPD Criminal Investigative Report of the 1 October Mass Casualty Shooting,” to give it its official name—offering the local-police-department summary of the Las Vegas gun massacre of last year... The report takes on the supposedly baffling question of Paddock’s motive, and what comes through is that—unless some astonishing new connection or fact appears in the future—his intention appears to have been purely nihilistic. Paddock wanted to kill a lot of people because he wanted to kill a lot of people. Feelings of frustration and insufficient power, the frequent ignition of such killings, may have moved him, too, and yet they seem to have been more unrooted than such feelings usually are among mass killers. He came from a troubled family, but had managed to acquire money, a girlfriend, an occupation. Basically, it seems to have been an item on his bucket list. He knew that the one thing he could do before he died was murder a lot of people. Why did he want to kill a lot of people? Because he wanted to kill a lot of people. So, he Googled any number of cheerful outdoor concerts, in California and Chicago and also in Las Vegas, and made reservations at hotels looking down on them, and kept buying weapons of mass murder, and finally, there he was, a little god of death."

"An AR-15 once again made an appearance at a mass shooting, this time at a Parkland, Fla., high school on Wednesday...These AR-style rifles have appeared in some of the deadliest shootings in the last few years, including a concert in Las Vegas, a nightclub in Orlando, a church in Texas and an elementary school in Newtown, Conn."

"Even though it’s illegal for the CDC to study gun violence and how to prevent it, there are still some data. One fact is that the AR-15 has emerged as a gun of choice for mass shootings—used in Parkland this week as well as Las Vegas, Sandy Hook, Orlando, and many other places now synonymous with tragedy. Meanwhile, in Kansas, a Republican congressional candidate is giving away an AR-15 as part of his campaign. Unlike pornography, the AR-15 was not a product designed for pleasure or fantasy, but for maximizing harm, a triumph of “wound ballistics.”"

"As officials continue to investigate 19-year-old Nikolas Cruz, who is accused of opening fire on his former high school Wednesday afternoon, killing at least 17 people and injuring more than a dozen others, familiar details are already emerging about the weapon police believe was used in the massacre. Police suspect Cruz was armed with at least one AR-15-style rifle and “countless magazines” in the deadly shooting at Marjory Stoneman Douglas High School in Parkland, Florida. This adds to a disturbing trend. In many of the most deadly mass shootings in the last several years, including the Las Vegas massacre on Oct. 1 and the shooting at a Texas church on Nov. 5, the lone gunmen were armed with assault-style rifles like the one reportedly used at the Florida school."

"On average, more than 13,000 people are killed each year in the United States by guns, and most of those incidents involve handguns while a tiny fraction involve an AR-style firearm. Still, the AR plays an oversized role in many of the most high-profile shootings, including the nightclub shooting in Orlando and the deadliest mass shooting in modern U.S. history: the attack by a gunman holed up in a Las Vegas hotel that left 58 dead and hundreds injured."
