The NRA favors paranoid people buying guns, and lots of ammo.
Quote from tomdavis:
He's a classic paranoid schizophrenic. I find it amusing that people try to classify him as being either on the right or left politically. He's neither. He lives in another reality. His behavior is a manifestation of his paranoid delusions of "brain washing" and "mind control."
I got first-hand experience with this when I was a sophomore in college. A guy in our dorm went off his meds, had a complete break from reality and became violent. Everyone on our floor ended up going for counseling with a psychiatrist who gave us a great explantion of what was going on. The shrink mentioned that late-teens or early-twenties is the most likley time for the major reality break and violent behavior.
Loughner lives in his own world. Not ours. Trying to apply logic to his behavior is a useless endeavor. Anyone who thinks they can logically "figure him out" is as delusional as the shooter.
