There is a lot of ignorance about mental health here. Lets find a couple of instances where bodies have been mutulated and apply it to all schizophrenics - silly.
Why don't you look and see how many mutulations were carried out by non-schizophreics, I think you'll find there are a LOT more who aren'!
Also Lookout, there are many, many people living with bi-polar disorder and the majority are NOT violent!
