I worked for a large police dept. for 6 years as a records clerk. I think most cops are good people. Still, my main takeaway from that job is that there is a widening chasm between cops and the general public, and it is bad.
I agree I think the vast majority of Police are good people. I think you have to be to do that sort of job.
However somewhere along the line I think some get a power complex or forget themselves.
Just before the lockdown, I went out in town with my work. The driver who picked myself and my friend up was a young lad and what I would class as a bit of a show off in the latest BMW etc...
Now he was doing 70mph through a town centre (speed limit is around 20 - 30mph), undertaking (illegal in the UK) and as I say showing off. Low and behold a cop car spotted him. He sped off and eventually the Police car caught up to him put the blues and twos on and pulled him over.
No word of a lie, the female officer came up to the drivers window and said to him very aggressively "Do you like driving like a cu*t? Because I am going to treat you like a cu*t?" Along with calling him other various names. Now while I agree with the officer that he was driving like a cu*t, in my personal opinion that is no way to speak to a member of the public and shows a lack of professionalism on behalf of said Police officer.
The above is only one example though and in my dealings with the Police, they have only ever been fair and approachable, although I have never been on the wrong side of them.
I do find though when I go over to the USA, that the Police are a lot more intimidating and feel as though I would be disturbing them if I said "good morning" or try to get into conversation with them.
