Unfortunately gun laws wouldn't be nearly as easy to enforce here, due partly to sheer size and population. Also proximity- many illegal guns (there are guns here that are not generally legal to own!) are smuggled in from Mexico. Banning guns outright are unlikely to make them unavailable, people who have malicious intent (gangs, etc.) tend to get them on the black market anyway. The vast majority of licensed gun owners have never harmed anyone, and the vast majority of violent gun users are unlicensed.

Responsible gun owners have been trained in their use, and the people who are allowed concealed carry- namely military members, cops, government people, bodyguards- have most likely been trained in controlling their fear as well and are unlikely to lose control.
