I was involved in a police attack, from local cops who did this.

Me and an acquaintance was pulled over. They were sure there would be drugs. They searched the vehicle because they driver wasn't properly licensed. We had no drugs, but we wished that we did, as this pissed the cops off real bad and they spend the next hour beating us. The driver was beat while handcuffed behind his back, by what must have been the most pussy-ass police sergeant ever. While he did that, his other officer beat the other guy's head of the cop car, who was with us, and the third officer kept a gun pointed at my head. The driver was the only one able to sue. He won an undisclosed amount.

During the process of making testimony towards the lawsuit, I learned that the city that employed them, openly knew this gang of cops routinely jacked people for drugs and money and had been doing so for many years.

The city paid the lawsuit. The police officers were fired and hired somewhere else promptly, with no loss to themselves and little concern. I think I read that the same cops ran some kid over killing him while chasing him in their cruiser, not too long later.

Because many like diluting things based on race: The sergeant and one officer were white, and the one with the gun to my head was black (he didn't beat anyone and said he was supporting his sergeant). All three of us, whom they assaulted are white. It doesn't seem that race played a role in these actions.
