Requirements to stop a car
If special law enforcement needs are involved - police may set up roadblocks to stop cars without individualized suspicion that the driver has violated a law
Supreme Court ruling on Roadblocks
Requirements:
(1) Stop cars on some neutral, articulable standard (i.e. every car)
(2) Be designed to serve purposes closely related to a particular problem pertaining to automobiles and their mobility (drunk driving - okay due to pervasiveness of drunk driving problem; drugs - not okay because the purpose of such a checkpoint is only to detect evidence of ordinary criminal wrongdoing)
