Elsie Law's Daily Dose Of The Law

"QUESTION: Are the rules for car searches different near the U.S. Borders?

ANSWER: Yes. Because the government has a unique interest in policing its borders at and around border crossings, police officers can search cars and their occupants even if they have no reason to be suspicious. The right to search in the absence of suspicion even extends to a vehicle's gas tank." -From, "The Criminal Law Handbook" By: Bergman & Berman-Barrett
