Police unions are common enough around the world, but internal controls are generally better than we hear about in the US (and I suspect it varies within America as well). I suspect part of the problem is that police forces run by smallish localities, which can't have the same level of training and oversight as larger jurisdictions. But that's only part of the problem: major US cities also seem to have problems.
