NBC NATIONAL NEWS — A ruling by the U.S. Supreme Court today limits the ability of police to take involuntary blood tests from DUI suspects.
The justices ruled that in most cases, police must try to obtain a search warrant from a judge before ordering blood tests for drunken driving suspects.
Otherwise, it may violate the Fourth Amendment, which protects people from unreasonable search and seizure.
