Miss. Cops to Drivers: Don't Pull Over for Flashing Lights It may be fake cop behind highway murders By Rob Quinn, Newser Staff Posted May 16, 2012 1:51 AM CDT Updated May 16, 2012 2:16 AM CDT 14 comments Comments Police suggest calling a dispatcher if you have doubts about the vehicle pulling you over.

Two people were shot dead near their cars in the space of a few days, and investigators suspect somebody impersonating a police officer could be to blame. "If someone attempts to pull you over with flashing lights and you feel unsure of stopping, DON'T PULL OVER," the Tate County Sheriff's Office warns. "Use your cell phone and dial 911, and if it's a real officer then the dispatcher will confirm it for you, and if it's not a real officer they will send help to you." "Our deputies have been told not to overreact if someone does not immediately pull over," the sheriff's office says. "Your safety is our primary concern." Police suspect the shooter was driving a gold unmarked Crown Victoria sedan, which can resemble a police car, ABC reports. Police officers say it's frustrating to know somebody may be abusing the public trust they have worked to earn. "It's very aggravating because it's law enforcement's reputation on the line," the sheriff of Harrison County tells WLOX. "When you have a bad guy out there abusing it, yes, it puts a blemish on us that we have to overcome."
