Maybe one life could have been saved if the shooter didn’t have such easy access to the additional bullets. It still doesn’t explain how someone with such a troubled past could so easily get his hands on such a weapon. Salon:

The high-capacity magazine of the semiautomatic pistol used in the shooting of Rep. Gabrielle Giffords and more than a dozen other people on Saturday would have been illegal to manufacture and difficult to purchase under the Clinton-era assault weapons ban, which expired in 2004.

According to police and media reports, the alleged shooter, Jared Lee Loughner, legally purchased a semiautomatic Glock 19 with a high-capacity magazine in November at a gun store in Tucson. Under the assault weapons ban, it was illegal to manufacture or sell new high-capacity magazines, defined as those that hold more than 10 rounds. The magazines used by Loughner had 31 rounds each, according to police.

If Loughner had been using a traditional magazine, “it would have drastically reduced the number of shots he got off before he had to pause, unload and reload — and he could have been stopped,” Daniel Vice, senior attorney at the Brady Center to Prevent Gun Violence, tells Salon.
