Thanks to tougher enforcement on the Arizona-Mexico border, more illegal immigrants are flooding into California in what the Orange County Register calls "the water-balloon effect: Squeeze one spot and illegal immigration will bulge elsewhere along the 1,952-mile frontier."
Noting that overall arrests have fallen a modest 3 percent since October, the Register reports they are up sharply in some places, including the San Diego area.
Arrests in the Border Patrol's sector around Tucson, Ariz., are down 9 percent to 345,973 since October compared to the previous year, though it is still the busiest corridor, according to the Register. During that same time, arrests rose 19 percent to 175,324 between the two sectors that span all but a few miles of California's border with Mexico.
Adding to the surge of illegal crossings in the San Diego area is the death toll among the hundreds of migrants who have died crossing Arizona's unforgiving deserts. Wayne Cornelius, a political scientist at the University of California, San Diego told the Register that his interviews this year with 724 people in the Mexican state of Yucatan disclosed San Diego was by far the favored crossing area.

San Diego was overrun by border crossers back in the early 1990s, the Register wrote, adding that hundreds of illegal crossers at a time stormed the world's busiest border crossing. Yet, an illegal immigration crackdown in 1994 pushed many migrants away from the border's two largest cities and into Arizona's mountains and deserts.
