"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."
