So my wife an I were leaving for a doctors appointment. Someone got pulled over in front of our driveway which is pretty normal but the back up unit was an Un-marked and tinted infinity. It had red and blue LEDs behind the grill and in the sun visors and had strobes in the head lights and tail lights. Looked like some sort of higher-up in the police department was driving as he wasn't in the same patrol type uniform. Also had plain jane Illinois plates
