There are countless videos demonstrating that some cops are power tripping. Some guy doesn't react quickly enough to a request and they get floored brutally while the cop screams at him: "Don't you dare f** with me or I'll turn you into a puddle you a*h**! Do you understand me! I said do you understand me!"

You might argue that hey, he has adrenaline flowing and so maybe he was a bit over the line. But they are professionals supposedly trained in effective deescalation techniques. Those techniques aren't just because it is humane, it is because it results in better outcomes. But the ego trippers put all that aside because they enjoy being the punisher.

Both of my grandfathers (and an uncle and a brother in law) were career cops. One of my grandfathers said: the power given to you as a cop either brings out the best in you or the worst.
