It depends on the situation some just need tough love and others need mental help.
I lost my Nephew who had Schizophrenia, he hung himself (so no gun) it was his second attempt. His father my brother inlaw had taken him earlier to the hospital.
An hour later he signed himself out (Prior to 2001 I think you could not do this, but the Liberals wanted to let people with mental issues run around).
Hi girl friend found him hanging in the basement he left behind a 1 year old little girl.
