You have a loner, who is into Goth which promotes death and torture among other very dark topics, a single parent, and more than likely on psychotropic drugs prescribed by a psychiatrist and there is your recipe for this disaster.

Instead of banning guns we need to ban the over prescribing of drugs to our youth. Also if your going to be a parent accept the job of raising your children properly.
So True.
