Thats the problem, you use force to keep some dirtbag from stealing and some greezzy lil' scumbucket trial lawyer will come along and make him rich.
I remember in my youth I went to work for Circle K and the manager showed use the new glass in the front of the store. They had a guy bring his riffle in to work with him. There was a big story in the newspaper about the heroic store clerk who wounded the armed robber as he fled the store with the cash. Police followed the blood trail and found the guy hiding in some shrubs in the area.
She said what the newspaper didn't report was the guy had taken less than 300 dollars. It cost nearly 4000.00 to replace the front windows the clerk shot out trying to hit the guy
