Obviously not as extreme but certainly much more common are those charged with assaulting a police officer who hurts themselves beating the shit out of a cuffed person lying on the ground.
One example is the case of Tyrone Carnegay where an off-duty cop working security though Tyrone stole a tomato, only to beat the shit out of him and finding the receipt. Then he charged him with assaulting a police officer and obstruction. Maybe he sprained his wrist as he hit Tyrone's knees with a baton while yelling get on the ground without giving him a chance to comply. He also lied and said Tyrone went after his weapon which the camera shows that he did not.
As I recall, even though he was charged with assaulting the police officer and obstructing a police, once Tyrone sued them, the police department was like "Whoa, whoa, he wasn't a police officer at the time while wearing his uniform but he was working for Walmart." in a case of being Schrodinger's cop. Some justice was eventually served in this case, though it still falls very short in my opinion, but there are many that never made headlines and had much public support. I'm pretty sure if the camera wasn't there and if he stole the singular tomato, he would have gotten much more than the 5 years former officer King got. I also bet if it wasn't for the DOJ getting involved King would have done probation, if anything.
