Let me add another statistic: 42% of Americans own guns at all, which means that those 393 million firearms are distributed among 140 million people, the vast majority of whom own one or two guns.
Completing that thought, some people own absolutely enormous numbers of firearms. Perhaps you've seen that photo of the family with over 400 assorted black military-style rifles and handguns on display in the back yard.
I want people like that completely disarmed.
More: suicide is about 2/3 of gun deaths. Problem is that firearm suicide is successful about 90% of the time while other forms are about 10%. People take a bottle of pills and just puke and awaken in the hospital just flying and with a headache. They cut their wrists and just cripple their hands.
There is no arguing that most gun owners aren't problems, they just own a gun to feel safer. But then, the tiny percentage who break into houses require us all to have locks and worry every time we're out of the house.
And gun advocates won't concede a thing; blind people who are mentally unstable need to be allowed to own guns.
With mass shootings coming almost daily now, and only bound to get worse, we need to start somewhere and it's a pity we didn't start back when there were fewer guns than people.
