SAN DIEGO (Border Report) -- One inspection checkpoint -- sometimes referred to as a "filter" -- has been in operation since November. Two more are scheduled to open in the coming days at the San Ysidro and Otay Mesa Ports of Entry. Tijuana Police officers and Mexican Customs agents will inspect northbound vehicles to verify passengers have proper documentation to enter the United States. Currently, U.S. Customs and Border Protection officers do these types of inspections as a way to prevent unlawful migrants from reaching the actual crossing to seek asylum. Pedro Montejo Peterson, head of Tijuana's Secretary of Economic Development, says having the American officers operate these checkpoints is counterproductive. He believes Tijuana Police and Mexican customs agents could easily handle the work freeing up the CBP officers so they can operate actual inspection booths at the crossings, and thus, shorten border wait times. Tijuana police to screen northbound commuters at port of entry "We're going to have three of these filters, we're also using private security to assist our police officers and agents," says Montejo Peterson. "The one installed on the right side, back in November, has had very good results and we hope these same results will be duplicated on the left side lanes of the crossings at San Ysidro and the one at Otay." Montejo Peterson believes this will ultimately lead to faster commutes at the ports of entry. "We're also looking to change the lanes of traffic heading north where the current Sentri lanes are located, we're doing a survey to study the traffic patterns to see if we can make changes, it should be concluded by Jan. 13," he says. In spite of Montejo Peterson's efforts as well as others, CBP has been reluctant to consider the filters as a viable option. The agency has said in the past that it’s always considering new methods to improve border crossings like San Ysidro, stating, “CBP’s San Ysidro Port of Entry is always in a continuous state of assessment, discussing and searching for the most effective ways to fully improve traffic flows and national security to the extent resources allow. This includes, when appropriate, leveraging the outstanding partnerships SYS has with local governments in Mexico.” Montejo Peterson says their intent is to prove the filters work convincing CBP to move its officers at some point soon.

"Hopefully, we can make them see the benefits so they will implement changes in the future."
