Please explain that to the parents of 8-year old Christopher Bizilj, who just blew his brains out with a 9mm Micro-Uzi submachine gun. At a perfectly legal gun show.
Actually, you don't have to explain it to Bizilj's father, who had taken him to the show, and stood by while an "instructor" -- we suspect that means salesman -- loaded the gun and handed it to the boy. When Christopher pulled the trigger, the gun's recoil made it kick in his hand. For the record, the Micro-Uzi can fire 25 rounds per second. We can't imagine what happened next, or how any of the people involved feel.
But we can ask -- and we do -- whether there ought to be any circumstances under which a young boy is given a loaded machine gun. Our answer, as always, is no.
