Holy crap people. Chill out. I never said let cops DO WHAT EVER THEY WANT.
From what I can see in this video, the cop was attempting to apprehend someone when this lady across the table jumped in and started touching the cop. Sure, I guess the cop very well could have been robbing her. I highly doubt it, but sure, I guess it's possible. You win.
Now, if I see a cop apprehending someone unlawfully I'll go support that person in court. I'm not touching the cop or killing him for doing his job wrong. We are not in the middle of an armed revolution in this country. You can't just shoot a cop for doing things wrong and expect it to be cool because it's justified in your mind. Go try it, have fun.
