And from what the video shows us, that ugly cop was possessed by an evil demon (as oppossed to just a run of the mill mean spirited demon). Watch at approximate 7:06 (aka 6:66) seconds into the video. The cop murmurs a bit. It's plainly evident that prior to the stop, his dark master, no doubt informed him via some kind of paranormal radio waves that the driver was a good and pure family man with a pregnant wife and children in the vehicle and that it would be easy to lure the driver into his wicked plan.
Whatever chemicals you're using at the moment, recommend backing off the dosage just a bit...
