For all the people (not here) suggesting that it's the witnesses, and not the cops, who are lying, they should really read this story. He was falsely arrested and beaten in his cell, and when they realized they had nothing to charge him with, they charged him with destruction of property - for bleeding on their uniforms. That later became a problem when he sued and admitting that he was bleeding became just a bit incriminating.
Surprise! It involves a black man. Fucking surreal. At least he got out alive.
