I'm not entirely sure how I gave that impression, jac. My view is quite contrary to what you apparently think they are. I think that society has a right to protect itself and that the label of mental disorder does not and should not negate the consequences of crime. I thought I'd made that clear.
I'd be grateful if you'd post the particular quote you're referring to so that I can clear up any misunderstanding.
Incidentally I have been the victim of assault by mentally disordered clients - on one occasion I was only saved from blindness by emergency laser surgery to prevent both retinae detaching. And you can stop wondering - I felt bleedin' terrible!
