I grew up in a small southern town. I was the weird kid, had funny hair and didn't wear cowboy clothes. I was pulled over at least seven or eight times for no reason. Once I was told I was being pulled over because some kids were playing mailbox baseball in the neighborhood I just left. Another time I was told the area I had just left was known for drugs and the cop wanted to find out if I had bought any... the area I had just left was an abandoned empty field in the middle of nowhere and I had simply drove through it as a shortcut. I've been told my tail light was out only to find it miraculously working went I went to check. I've been told I fit the profile of another guy who was throwing bricks at a house. If a cop doesn't like the way you look and wants to release some aggression, they will make up any excuse to pull you over. I did know my rights so all the examples I mentioned didn't lead anywhere, I worry what those times would have been like if I hadn't been white.
