Contrary to some popular opinion, the U.S. Constitution does apply at U.S. border crossings, so U.S. citizens have rights of free speech and association, freedom from unreasonable searches and seizures, and freedom from forced self-incrimination.
However, U.S. border agents also have broader powers than U.S. police officers, including the ability to conduct warrantless searches of vehicles, luggage, and other possessions. Put another way: in the United States a police officer can’t pull you over, then search and disassemble your car unless they have probable cause and a warrant approved by a judge. However, a border officer can, no warrant needed.
