A Louisiana media outlet discusses the increasing use of social media to raise immediate awareness anytime a new DUI checkpoint is set up. The article describes the notification of roadblocks as ‘Cheating Checkpoints’. While the Supreme Court has upheld such roadblocks (despite the lack of reasonable suspicion or probable cause to believe a crime has been committed) others would call it a public service by alerting those who have committed no crime and believe that this type of police conduct violates their civil liberties. However, the law REQUIRES that for such roadblocks to be constitutional the police must give ADVANCE NOTICE. This is a another example of media ignorance.
