Cop sees car/truck speeding (traffic infraction). Cop turns on light and siren. Car/truck speeds up to flee being stopped. You are an idiot if you think the cop should go get a donut!
You must be the product of government schools. Get someone to read my post to you. I said nothing about going for donuts.
That must be how the cops you know spend their time for it to be the firs thing that came to mind. You should get out and meet some GOOD cops.
