An ex-brother-in-law is an SFPD cop. We were close friends as teens before we met our respective wives (sisters). He was a punk, always in trouble with cops. He became a cop, and would tell me stories about cops beating the crap out of people. Later, he mellowed out and no longer wanted to be around the bad apples. As you say, things have gotten worse over the decades. A neighbor of mine is the widow of a cop killed a decade ago. Either side getting killed hurts the families who are left behind. Not good.
Live and let Live (don’t harass) would be a good 11th Commandment.
Not good when we lose the Rule of Law and impose the rule of man.
