UK has some, albeit isolated, dodgy incidents.

Had six coppers on top of him and died during his arrest. The whole thing was a mess because they tried to portray the guy as an aggressive monster with a track record of violence. The reality is he was a family man who took some drugs one night and had a bad trip. He grabbed a knife from his house and wondered the streets, threw it in a nearby garden and carried on walking about. The police said they saw him with the knife, which he no longer had when they came on to the scene. He hit a female officer who was there before the rest and carried on wondering about, but the police (the ones who weren't on the scene yet, not the one he hit) stated that he was stomping on her when she was down. The cops said that he was physically imposing and a strong lad, which he was but he was still shorter than two of the officers and 100lbs lighter than one of them. Yet they sped towards him, stopped their vans in front of him, and without any warning of mention, ran to him with sprays in hand, jumped on top of him and stayed that way for a few minutes whilst he screamed "get off me".
Nobody comes out of that situation very well but the police tried covering it up and only now half a decade on is his family finally getting answers.
It's one of those cases where, if you really wanted to, you could say "well, he shouldn't have been off his tits on drugs, walking about with a knife before throwing it in a garden, and punching an officer" but does that mean he deserved to die and then have his reputation destroyed in the press due to misinformation being spread by the police?
This was my hometown, everyone knew Sheku or someone who knew him and they all said the same thing. He was a good guy, everybody's friend. He never started fights, and always walked away when someone tried to start on him. There's incidents like this every day and every now and then it goes too far and someone loses their life.
