a friend of mine was a bartender for over 10 years and she didn’t have many nice things to say about cops. Big cheaters and drinkers. I used to tease the cops I knew saying, if you hadn’t become a cop you’d be in jail. They’d laugh.
I’m not a fan of blanket statements, but I think your comment is more common than people think. I was once married to a police officer (long, long time ago). He would say that as a cop, he could raise he11 and get away with it. That’s what the “thin blue line” meant to him.
Most cops (and cop’s spouses) go to their graves with perfect driving records. It’s not because they are better drivers. Immunity is quite a perk of the job, but most cops expect it as professional courtesy.
