| SAN DIEGO, May 17 (UPI) -- The U.S. Border Patrol said it has become necessary to top a five-mile section of border fence with Mexico with triple-strand razor wire to battle smugglers. The Los Angeles Times says the "concertina" wire has been added to the existing fence separating San Diego from Tijuana, Mexico. The move marks a major shift for the Border Patrol, which in the past has shied away from using such fencing because of the negative connotations its appearance creates. Border officials told the newspaper that escalating violence from human smugglers has created the need for the new fortifications, specifically from Colonia Libertad, a notorious Tijuana smuggling enclave. U.S. officials contend the razor wire has proven to be effective in controlling the smugglers. |
