well since my guess is that they prolly make up 1% to 3% of the population(i don't know the ratio) i'd say that's a pretty high percentage!
Before accusing a segment of whining, try to nail down some facts. Such loaded language coupled with admitted ignorance scarcely wins agreement from anyone who didn’t already agree with you. To put it bluntly, you risk looking like you’re projecting.
I’ve heard 1 in 5 inmates are mentally ill. That’s a helluva number of people and it also shows they’ve already committed crimes.
Yet when such persons are charged for their crimes, the defense is "not guilty by reason of insanity". If you cannot be held accountable for your actions at any time, then you do not have the right to roam freely among society without a legal guardian.
