There.....get it now? The ACLU punk rolled his window down just a crack......very reasonable for the cop to suspect he didn't want the cop to get a whiff of his breath. Then the matter of his avoiding conversing with the cop.
the jury (or judge) in any civil action will show this twit the door.....that is if any civil suit survives the motion to dismiss based on the 2 statute section/paragraphs posted above.
...looks simple to me...since when is rolling down a window part way reasonable grounds?
I have a problem with DUI checkpoints, but I figure they are the price to pay for driving. My problems are:
---if you don't shut up we'll find something to write you up for.
---they told him to get out of the car, then got into the car to move it, despite his offer to do so.
Both violate constitutional protections; the first is incredibly rude. I support any LEO who does his job and stays on the right side of the law; if he doesn't, then he's no better than any other criminal, is he?
