I don't believe it's all of them either.
I would guess maybe 10% of them are decent people. But most of those don't last very long.
The other 90% are no better than the scum they arrest. Nothing but gangbangers with a badge.
Actually about 10% of them are corrupt, but the others are just as bad because they look the other way, and lie and cover-up. They talk among themselves in code so that they never have to respond to the public in their terminology in regard to their corrupt acts.
What makes it even worse is the Court takes the cops word 99% of the time because law-enforcement has to be trusted or we have a third world country where all the cops are on the take and the legal system is a joke. We've been heading that way, just barely holding on to some semblance of justice and fair play.
