Mobile Police Scheduled to Conduct Safety Checkpoints

"On Tuesday, July 23 and Tuesday, July 30, 2013, Mobile Police will be conducting Safety Checkpoints in various parts of Mobile. The checkpoints will be conducted to ensure citizen safety and that motorists are complying with state and local traffic laws.

Police will be checking seatbelts, child restraints and other safety features. Officers will also be checking to ensure drivers are carrying registration, proof of insurance and driver’s licenses, as required by law." 

As required by law? The law says the we have the right not to be searched unless upon probable cause and by warrant. There have been exceptions made but this isn't one of them and is directly contradictory to what the constitution requires. They're saying they're going to uphold the law by breaking it.
