I had a cop rush me because I pointed out the bounce in a Houston bar that I was being admitted for having sneakers on but 3 white guys in front of me had on hats, flip flops, and sneakers. I was talking with the bounce and called him a racist. A cop without any verbal warning pushed me off. My friend started arguing with the police, the cop grabbed and literally threw her out. Then he went and shoved me again but this time I fought back and we were separated by 2 cops.
I didn't get arrested though. I know the feeling too well. This is one of the main reason I don't go clubbing in the US, too much racial BS.
