There has never existed a law that prevents stupid from happening. Think about it like this... people who are dumb are already carrying firearms when they go get drunk. A law either way is not going to chance that basic reality
"Gun control: The theory that a woman found dead in an alley, raped and strangled with her panty hose, is somehow morally superior to a woman explaining to police how her attacker got that fatal bullet wound." — L. Neil Smith
The problem with being stupid is you cannot simply decide to stop doing dumb things...
