In Philly a case just got tossed out because the cop was lying on the stand. Surveillance video directly contradicted his sworn testimony. If that video hadn't existed a person who had their rights violated would be going to jail, (yes, the cops found some weed. But they violated the law to try and make their case). This why shady cops hate video and some, (who aren't shady) don't mind it. Hopefully at some point every action the boys in blue take will be videoed, for the protection of the good ones and to the detriment of the bad ones.
