This collection of police video leaves no doubt which side of the blue line it stands on. Police officers have uploaded and commented on most of these clips, and the site is hosted by the law enforcement resource PoliceOne.com. But even the most confirmed skeptic of Joe Friday will find something fascinating in the selection of unvarnished footage—most of it from in-car police cameras—stationed among the local TV reports and musical montages. Watch a man fail a DUI test before it begins, see a lady attempt to wield her womanly ways to avoid arrest, and peek behind the scenes of a a K-9 service dog's training. Finally, don't miss the astounding "Greer Train Collision": one car, one train, and an officer who gets the driver out of her vehicle in the nick of time. There's no audio for the first 1.25 minutes, but it's worth the wait.
