"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."
