It WAS a great learning experience, though. The cop learned something about firearms safety and the staff know what a firearm sounds like when it's shot inside the building.
My dad was starting work at a shop that made propane tanks. On his first day the foreman took him around and introduced him to the other people and gave him a safety briefing. When they got to the big metal shear the foreman put his hands under the blade and said, "Whatever you do, never put your hand here and push that button." And then he pushed the button. He lost all the fingers on his hand when the blade came down. My dad said it was one of the best learning experiences of his life. He never put his fingers under the blade after that.
I just thought I would shine a positive light on the situation.
