What law would I be breaking if I refused to show you my ID at a checkpoint like this?
P.S. I'm not baiting. I really want to knw what the ramifications would be. Because from what I have looked at, a DUI checkpoint is perfectly legal. But there are no laws in the books I can find that relate to License checkpoints.
