I have a mate who is a cop. Psychologically it's interesting to speak with him because he cannot take any, and I mean any, criticism of the police. At all.
He's a good guy but he was the guy at school (like most of us) who had very little respect or authority and it always felt like being a police officer was a way to get that authority where people have to listen to you.
We once had a heated discussion where I, off the cuff said that the police were allowed to lie, he lost his shit, started raising his voice telling me that I didn't know what I was talking about, the police cannot lie to you, no office is allowed to be deceitful, I'm a lefty idiot and swallowed this woke agenda etc (we've known eachother twenty years and are mates). He got really angry. It was odd. More so when I asked "what about undercover police?" And he just fell silent and the rest of the group kinda awkwardly laughed and the conversation moved on. But it is these kind of exchanges where you get an idea that he truly believes he is some sort bastion of good and truth, yet he's just swallowed what he has been told and what his colleagues say.
My other mate who is also a cop, was a proper lad at school, confident, shagger, alpha type guy but a decent bloke. Was in the military etc. When you talk to him, it's completely different, he does the job, is relaxed, doesn't need to exert any kind of influence, knows that the police are fecked, moans about the bad people, dislikes the dumb policies and actually "gets it".
I think being a policeman/woman has the power to corrupt and bring out the worst in people, also people who are drawn to having power usually aren't great. I think the actual job can make people really cynical as well, some of the things you see are brutal and grim.
Bit of a ramble
