Fake Cop Pulls Over Real One Detective pulls him over right back By Kevin Spak, Newser Staff Posted Jun 6, 2014 12:40 PM CDT 31 comments Comments Damon Wayans Jr. and Jake Johnson are seen in a screenshot from the trailer for the upcoming movie "Let's Be Cops." (YouTube) (Newser) – The problem with impersonating a cop is that at some point you might run into a real one. Florida Detective Justin "Chance" Anderson was driving an unmarked car Monday when a 1999 Ford Crown Victoria Police Interceptor he'd passed turned on its red-and-blue flashers. Anderson obligingly pulled over. The other driver "pulled up next to me. Kind of gave me the 'slow down' look and pointed this finger at me," Anderson tells First Coast News. Anderson was "shocked" that he didn't recognize the "officer," who then drove away. So Anderson turned on his own flashing lights and pulled the "cop car" over right back. Its driver, Matthew Michael Lee McMahon, 20, rattled off several explanations for why he had the lights. Anderson let him go, but soon determined that his story wasn't true—and that he'd never been an officer. The next day, McMahon came into the sheriff's office to turn in the flashing lights, and bumped into Anderson, who arrested him, the Florida Times-Union reports.
