Unmarked police car...................?

In my town, all town cars (ex, squad cars, fire police cars, etc.) have MG on the front, such as MG-697-07 or whatever. Did he have a blue light in his car and that's why you pulled over? If you just pulled over cuz he was tailing you and he got out and just bitched at you, it might have BEEN jim bob in mommy's car.. if you got any part of license plate, you can report him. =) If not, well then... I guess you got off luck! O_o
