Head-shop CCTV catches police informant/undercover planting crack

Cops destroy video on a regular basis if it serves their interests: they confiscate/steal video phones regularly without even hiding the fact. Surreptitiously stealing or deleting video is hardly a difficult or risky thing to do for the police. And the “disappearance” of the informant is highly suspect as well. This case stinks to high heaven, and do we really need to debate whether law enforcement is capable of dissembling and corruption at this late date?
