I don’t believe a word of what you posted.
I'm sure it happens, but I have yet to see it.
I’ve had plenty of trouble with police officers in my lifetime but since growing up, I look back and realize I was the one responsible for the trouble each and every time. In most cases, officers were far more tolerant of me than I would have been.
You may not agree with a speed limit but that’s too bad, speeding is still illegal. Same with drugs and only a moron takes their disagreement with the law out on the cop.
