I think the key word is "relatively" For whatever reason stop the meds or just go off on something..boom right?
I have no problem with anyone being a part of civil society as long as those who may pose a danger, behind them is SOMEONE taking responsibility for and do notify anyone who may be in danger of it and in a timely manner to AVOID a Newtown.
When no-one is taking the reigns no-one will be held responsible. Sorta like fast n furious, and Libya.
We need responsible adults in charge not screaming idiots pointing fingers ELSEwhere
