First, police officers do not call it a sidearm, military officers do.
I live in NYC and cops around here call it as a last resort.
Actually I live in Brooklyn and we have the best cops 68 Pct. and the best firemen, Rescue 2!
I love America, but I feel safe in Brooklyn, New York!!
I've never served as a police office, only in the military, so I am biased in my jargon by previous life experiences. I am sure that you are correct as to what terminology the police use. I am guessing that policemen everywhere in America call it a "last resort", and I am delighted that Brooklyn has citizens who will testify to the professionalism of their police forces. We perhaps could use more of that sort of thing. Thanks for the reply.
