John Swartz was a passenger in a car driven by his wife through St. Johnsville, N. Y. in 2006 when the couple passed a police officer tracking cars with a radar gun. Swartz apparently disapproved of the speed trap, which he expressed by sticking his hand out the window and raising a one-finger salute in the officer’s direction.
The police officer then followed them to their destination, turned on his lights, and asked for license and registration. Three more officers arrived as backup and Swartz was then arrested for disorderly conduct after he allegedly yelled at the officers about being humiliated. The charges were thrown out, but he filed a malicious prosecution lawsuit against the police which will now be allowed to proceed.
