I live in San Diego and I can tell you that CBP most certainly does conduct searches on anyone passing through their secondary boarder checks. When I drive to LA I would say 1 in 5 times the secondary checkpoint is open in Oceanside and you have to slow down and at the very least get waived through. CBP has every right to stop and question you if they feel the need though.
