I’m British, and I wouldn’t say so. In some higher profile cases cops might lose their job, and in extreme cases they go to court, but it’s really rare for the charges to stick. There was a recent case with a famous sportsman - a pair of cop tased him, beat him with a baton, and kicked him in the head until he died. That was the first time in over 30 years a cop had actually been found guilty of manslaughter, but the other cop escaped with no charges. The bastard that got sentenced will almost definitely be released within a couple of years.
So, yeah, if it’s high profile enough, maybe, to some extent, but otherwise, no.
