The video shows a polite cop giving a warning in one stop, then trying to give another warning during the stop in question despite obvious provocation efforts by the "black lives matter activist". He finally snapped and she got what she wanted.
The FULL video showed me a Texas state trooper trolling on a college campus for college cuties, because apparently, Campus Safety didn't have their jurisdiction under control. LOL!
He was obviously provoking her. He pulled a U-ey, crawled up her tailpipe, and waited for her to make the lane change without signalling, as most people would forget to do under the stress.
And then, she was supposed to like it, and smile for the brownshirt goon.
She should have put her cigarette out in his creepy eye.
