Just because you’re not intoxicated doesn’t mean you can’t be arrested at a DUI checkpoint. From Eric Peters at theburningplatform.com:
Did you know that when you’re stopped for no reason at a drunk driving checkpoint – well, stopped for no reason having anything to do with something you did to suggest you might be “drunk” – your refusal to participate in self-incrimination can result in your arrest, loss of your government permission slip to travel as well as the impounding of your car?
Your “cooperation” is not only appreciated – it is required.
This not-much-discussed aspect of Checkpoint USA is arguably even worse than the existence of Checkpoint USA – which came into being in the ’80s, when the government decided to re-interpret the limits of its own authority (a problem with government) by summarily decreeing it to be “reasonable” to randomly and arbitrarily stop people and treat them as presumptively guilty of having committed a crime.
The thing George Mason and others who insisted on the Bill of Rights as their condition for reluctantly supporting the dodgy Constitution (which was confected by an elitist minority, behind closed doors and without any mandate from “the people” mentioned in the Declaration of Independence) feared would come to pass had come to pass.
