I think this is why most of our leaders do NOT want to take even one step towards examining this part of Adam Lanza, Shui, Loughner or any other psycho killer including Harris and Kleybold whose medial records are still sealed; most of our leaders are gobbling down the skittles by the handful for their various 'ailments' and they know damn well they are way too ####ed up, all the time, to be having any sharp objects lying around let alone firearms and don't want us to know it.
I mean, come one. Every Happy Pill on TV comes with disclaimers that talk about 'thoughts' of suicide, mood swings, anger issues and various and sundry warnings that you might be worse off if you take this crap.
