Giffords shooter fired 31 rounds
That settles it. He was limited to the amount of bullets he could shoot without having to reload. Conceivably he could have bought a fifteen-year-old piece of equipment even if the 1994 law were still in effect, because it banned the sale of
new magazines with greater than 10 rounds. But it seems very possible that if the law had been renewed in 2004, today there would not be 20 lives inalterably affected, and 20 families devastated.
