This year cops in several states have announced intentions to set up sobriety checkpoints where holiday revelers will be forced to surrender their constitutional rights in the name of safety.

In many states, such as Texas, drivers may even be subject to mandatory blood draws if an officer merely suspects them of driving under the influence.

The Supreme Court says checkpoint stops are seizures within the meaning of the Fourth Amendment, meaning they technically violate that constitutional right. However, the court has ruled that the states interest in preventing drunken driving outweighs Fourth Amendment protections.
