On November 28, 2000, the U.S. Supreme Court ruled that state and local governments may not set up roadblocks to catch drug offenders, despite WLF’s brief filed on May 15, 2000, which supported the constitutionality of such roadblocks. In particular, the Court rejected WLF’s contention that the roadblocks were lawful whether or not conducted for the purpose of criminal law enforcement; the Court concluded instead that the Constitution did not permit suspicionless searches for the general purpose of crime control.
