There is fine line in american justice. If people have mental problems that cause them to kill ppl or hurt kids, then you put them in a psych ward for a while? Unfortunately no country has a perfect. Hey, we are doing the best we can.......I once saw a story about a guy who was in vietnam and he snapped and killed his whole family. He was found not guilty by reason of insanity and stayed a few months in a loony bin, then he was released only to start a new family and kill them too. Its hard to know who is capable of rehabing and whos not.
