Yes, yes, a handful of police officers breaking the law means all police officers are assholes. Just like a couple of citizens breaking the law means all citizens are assholes. Great job, everyone.
Honestly, this is simple to solve. The police should start taking videos of everything they do as well. If an edited video pops up of them doing bad things, then they can simply post the video from their perspective. Now no more "look at this video of a cop beating this innocent man" AFTER the supposed "innocent man" kicks the officer, except not on camera or edited out. Mass surveillance works in every way. Govt. -> public -> police -> public.
