I've long maintained the people talking about gun crime being a "mental health" issue need to cool that shit.
You want hell, have psychologists determine what you can or can't do in your life.
And you can't argue out of crazy, the more you deny being crazy the crazier you look.
It is easy to make it sound reasonable at first, we don't want mentally unstable people getting guns, but then you meet the people doing the analyzing and learn what they consider mentally unstable... and you're fucked.
Like when a father jokes about any guy touching his daughter getting shot... Not going to be funny when a psychologist gets ahold of that info and now everything including your pointed knives are removed from your possession.
But it was a joke... I wouldn't actually... yeah, well, prove your innocence, you've admitted to murderous intent, we believe you, so, now you have to prove you're not violent.
A law requiring a psych eval would be hell, that tends to go for anything as well, driving, having kids, etc... you don't want psychologists deciding people's lives.
