I will talk the truth in these matters
my father was the asst cheif of pooolice
he told me stories about corrupt cops who would beat people down for no reason
one time a cop working with him told him to shoot a black man in cold blood
my father told the other cop to shut up -- he wasn't going to shoot anyone
most cops are good -- but -- some are evil
That caused me to remember something. About 15 years ago I hired a guy in my business that had recently retired from the local force after 20 years. He was only in his mid-forties and wanted to embark on a second career. Nice guy, not a brute or bully type in the least, degree in Criminal Justice, well read.
He worked out very well for us, a very good employee.
One night near closing we were chatting and I asked him if he missed being a cop.
He kinda changed a little, physically tensed up, a little excited and answered:
"Just one thing, the adrenalin rush".
He went on to explain he got that rush during any routine traffic stop, but more at night, because you never knew who it was in that car, flashlight and hands ready, sidle up close to the stopped vehicle, watch the hands, remember the training and hours at the range.
He surprised me. I really think the only thing missing in his 20 years of service was he didn't have to shoot anyone.
