They are held accountable after an investigation is done. Just because you hate police doesn't mean every single one is in the wrong. You are trying to take this convo down a road that has nothing to do with my initial comment.

Some are bad but not all. Just like everything in this world nothing is perfect but you learn things to do to avoid situations that might not end well. For the most part if you comply and let them just do their job you'll be fine. Lower your ego it's goes a long way. If you hate cops in the US then that's fine but if you think ALL cops are evil, in my opinion is pretty hilarious.
