Probably time to get to the real problem here, which is not that a lot of people have guns, but that a lot of people think it is ok to shoot them at other people when they feel threatened or angry(or stab them, or blow them up).

This is only part of a larger problem that includes cutting people off in traffic when they do something you don't like (there are estimates that road rage figures in 60-70% of traffic accidents), and calling someone who disagrees with you on an internet forum childish names.

A lot of people in our country (you know which country I am talking about) feel entitled to aggressively confront anyone who does something they don't like. Though we recoil at the extreme examples, we tolerate it and even applaud it in everyday situations.
