One thing the shooting proves is that strict gun control laws don't prevent mass shootings or high crime rates (just look at Chicago or even DC). Not so sure banning high capacity magazines will make much difference either b/c criminals ignore the law anyway and can do end runs around the law via smuggling/black market (or becoming very adept at switching out clips very quickly). That said, you both make very legitimate points. I see no reason responsible law abiding gun owners should be penalized b/c of some crackpot, but neither should they have a big problem w/being extremely careful to keep their weapons secured when they're not using them themselves (gun range, hunting, etc..).
