The truth is that in a chaotic situation, even highly trained police officers often kill bystanders. The idea that some accountant who spent a few hours at the range would suddenly turn into Jason Bourne and take out the killer without doing more harm than good has no basis in reality.
from Ten Arguments Gun Advocates Make, and Why They’re Wrong.
One thing I never figured out or become familar with while living in the US was the American gun culture. Chalk it up to culture crash or whatever. It’s not like most of my friends had assault weapons lying around. The Sandy Hook killings are horrible, but sadly not unique. From my outsider’s point of view, at least, it seems more and more ridiculous to insist that laxer gun laws will make everyone safer, when evidence of the contrary makes itself painfully clear every few months.
