First of all, I admit, I did not read all six pages of this thread so please excuse me if I repeat someone elses comments.
OP, do you honestly think a safety course would have prevented the recent trajedy? Do you or anyone else believe that any law would have stopped it.
Since the 1000's of existing laws don't seem to cure the criminally insane, I just don't see how a few new laws are going to help. Maybe a law banning our media from broadcasting the criminals name over and over for weeks straight thereby making them famous would help. No fame or glory....maybe that will work?
