I cant even begin to say how I feel. A very young life has been ended due to total and gross negilgence. My prayers are with this mans family. You must be totaly sure of our target and what is beyond it. The other thing that has always bothered me is the use of a 22 cal for hunting squirrels that are in a tree. The bullet travels way to far to be shooting in the air. I do use the 22 but never shoot them while they are in a tree. ( only while they are on the ground ) If you want to hunt them in a tree use a shotgun with #6 or #8 shot. Those pellets don't travel very far and are much safer for others in the woods.
