This video shows how a border barrier caused dramatic change in San Diego during the 1990’s. The Border was at one time in absolute chaos. It’s still not totally secure, because the old barrier is far from perfect, but about 90% better. The reduction in crime and smuggling has improved the neighborhoods on both sides of the border. This video was produced by the local Border Patrol sector command in San Diego. It was shown to President Trump when he visited the border-wall prototypes.
