People who really want to be cops are scary. While I was in the military there were always these beer or liquor-infused bull sessions where dudes would sit around and talk about NCO's lashing out punishment on troops and the storytime element of humor or whatever else was of interest would sort of keep my attention but there is that group of people who really get off on the power dynamic. Obviously, plenty of police are doing the job for honorable reasons. There are those scary types who are in playtime for the TV show in their heads.
