So basically, you're screwed because the fox is guarding the henhouse. This is one place where ubiquitous surveillance can be a good thing - police cameras (body cams, dash cams, and police station cams) should be unalterable (with footage signed by a neutral 3rd party with civilian oversight) and non-disablable, if a police camera is turned off or is blocked, it should send out an "officer assistance" signal by radio, and courts should view police actions skeptically when they happen outside of camera view. Release of footage can still be governed by the courts to protect suspect privacy, but there's no reason that a police officer's official actions should be kept from the public.
