Tragic Death of a Gun Instructor by a 9 Year Old

What happen to the gun  instructor was an accident.  He was killed when a 9 year old   fired an automatic gun and she   couldn't handle the recoil.  It's a sad tragedy but I still believe that   kids   need to be taught the proper handling of guns and  teach them the importance of it.   My husband taught  our daughter how to fire a small gun  when she was 7 and she  likes the fact that she can defend herself  if there is  a worse case scenario that she needs it.  I pray that nothing happens like that though. On another note, I finally   found heat guns online .  Hubby  designated me to find this kind of gun that we can use on our project downstairs.
