"Even war as a metaphor the war on drugs, for example can have a dramatic, and unequal, effect on civil liberties, as shown by the recent revelations of how widespread racial profiling had become before the public even had a name for the practice. 'You fly the metaphor of war, and constitutional protections all cut in one direction,' said Dennis J. Hutchinson, a law professor and historian at the University of Chicago. He said the 'deconstitutionalization of the automobile' the ever wider discretion for police searches for drugs 'is the most obvious recent example of panic moving the terms of discourse.'"
