It's not a mistake and occasional bad judgement that is the hung juries and acquittals we see when the evidence objectively is overwhelming against police defendants. (People have been executed based on far less evidence, e.g., no video.) It is this result that tells us that police are widely corrupt, as society countenances their corruption. Apparently, society countenances smoking pot; and we see how pot smoking is almost nonexistent as a result. Oh, wait, I'm not Plainthinker, so I realize that the countenancing does the opposite of keeping it to a minimum.
