I live right on the border of Harris and Galveston County so I see the regulars all the time. This one was new.
This was a Mercury Murader with Constable Pricinct 3 badging. I've never seen this car before and couldn't catch up to him to check the county of orgin. I only got this close because we got caught at a light.
He didn't have a hard mount radar system just a scanner and a laptop. Could have had a handheld maybe. Also he did not have tax exempt plates. Won Hunglo maybe you could be of some help since you seem to be pretty knowledgable about these things.
Sorry the picture is crap but he was hauling a** and I didn't want to try and keep up.
