I can’t believe the officer tried to use a tazer on the guy in the first place.
Using a Tazer on an armed robber? A pawn shop owner that, apparently, was not armed? Hmmm.... Not where I live, and not in my favorite pawn shop. In my fav pawn shop, they would have taken care of business, and the sgt would be alive and complimenting them on excellant gun control.
Fear of litigation.
