"The incident began at around 2am. Darrow [the motorist] was to meet a friend who was working late and was going to pick him up. Darrow headed toward a 24-hour commuter parking lot in an unincorporated part of Saint Louis County in his 1997 Nissan Maxima. He put on his turn signal and entered the lot which, aside from Kuehnlein's cruiser, was essentially vacant. After stopping the car, the police officer approached and began questioning Darrow about what he was doing. When Darrow declined to discuss his personal business, the police sergeant exploded. Although the video clearly shows Darrow driving properly and using his turn signal, the police officer insisted that Darrow had broken the law."
Had Darrow not had his own video camera running it would have been his word against the police officer's. He has had another interesting run-in with the police that he captured on video as well. In both cases he's merely asking the questions any citizen should be able to ask of a police officer. In both cases, the police do not respond well."
