Mark May, a self-employed carpet cleaner from rural western Indiana, was driving his car through the town of Terre Haute on Aug. 17 when he spotted an Indiana State Police patrol car zooming up from behind.
As May slowed at an intersection, the police vehicle cut in front of him — too aggressively, May thought, according to his federal lawsuit. If May had pulled that maneuver in front of a police officer, he would have earned a ticket, he believed. May correctly guessed that the trooper was pulling ahead to stop another motorist, and as he passed the patrol car, he signaled his displeasure.
