Dozens of Texas drivers have been stopped at a police road block, where they were then directed into a parking lot and forced into surrendering blood, saliva and breath samples in a study that has upset civil liberties advocates.
The National Highway Traffic Safety Administration admitted it was attempting to conduct a government study meant to determine the number of drunk or drug-impaired drivers on the road at any given time.
