Electra Glide in Blue is a 1973 film starring Robert Blake as a motorcycle cop in Arizona and Billy Green Bush as his partner. It was produced and directed by James William Guercio. The name stems from the HarleyDavidson Electra Glide motorcycle issued to traffic cops.
Wintergreen gets his wish, but his joy is shortlived. He begins increasingly to identify with the hippies whom the other officers, including Detective Poole, are endlessly harassing. The final straw comes when Poole discovers that Wintergreen has been sleeping with his girlfriend Jolene Jeannine Riley. The hostile workplace politics cause him to be quickly demoted back to traffic enforcement.Despite being demoted, Wintergreen is able to solve the murder. The killer turns out to be Willie, who confesses while Wintergreen goads him into talking about it. Wintergreen surmises Willie did it because he was jealous of the old man he killed, who frequently had young people over to his house to buy drugs. Shortly after, it is discovered that Zipper stole the 5,000, which he used to buy a fully dressed Electra Glide motorcycle. Wintergreen is forced to shoot Zipper after he becomes distressed and belligerent, and shoots an innocent bystander while brandishing a gun. ........
