oh, I feel for the shooter as he must have been "off" and it sounds like the justice system failed him by not making sure he was no menace. wouldn't have taken too deep of a look to see that he was dangerous.  and as to the trauma he caused...yes, much on both sides.  BUT he did kill a stranger in a park, so ...there's that.  +++guns are easy weapons to kill with - people kill themselves and others just playing with them -   they are weapons of impulse - .  they are weapons of inflicting a lot of damage in a very short time. -  they are weapons of cowards.  footballer will smith - unarmed and shot multiple times in the back.  who does that?  if the killer had no gun...he's gonna jump on smith's back?
