I was getting gas this morning and I noticed a brown metallic Ford Crown Vic pulling out from behind the gas station. He had two spotlights and a push guard on the front. Tax Exempt plates and a series of antenaes running across his rear trunk and red and blue lights behind the rear blacked out windows. The guy driving it looked like a Harris County Constable. White short sleeved shirt with a gold badge. He had a white cowboy hat sitting on the dash so i couldn't tell if he had a radar unit up. No rear radar antennae I could see. Also, no red and blue lights in the front grill either but i could have missed them. I was really trying to ID the driver and check for a radar unit.
Not likely anyone savvy about police cars would ever miss it in traffic but i haven't seen this kind of unmarked unit before. They're usually white Crown vics.
