In Mexico they are openly corrupt and dispense life and death to the people who fear them as we would fear gang members. In China (I've visited there and seen it) they control and profit from prostitution and are the pimps. In Europe in countries like Poland, France, Czechoslovakia, and several others the people still remember how their friends and neighbors on the police force became the enforcers of Nazi policies over night and began turning them in and how they automatically shifted depending on where the wind was blowing from. In America, I assume there are still people alive today who remember how the police were the seat of power for the Ku Klux Klan down South and how they loved beating on striking workers during the depression. I think hatred for the police is deeply seated in all societies. I've never been to a country where they generally love the police. Maybe one day we'll have robots programmed to treat people without emotion that act as our police.
I don't mean to sound like I hate the police. I treat them with respect and fear them. I've been very happy to see a cop when my car has broken down on a dark and lonely road. At the same time, I've had guns pulled on me for no reason. I've been unapologetically dragged out of my car at gunpoint in front of my girlfriend's house, slammed on the pavement, and had my hands cuffed because I allegedly looked like a suspect they were looking for. I WANT the police to be good guys and I don't enjoy hating on them. They aren't always the good guys and every time I interact with them I know my blood pressure goes up and I breathe a sigh of relief when they've gone. To me they're unpredictable.
