A group of National Guard soldiers from Virginia watches for illegal crossers on a hill about 100 yards from the border near Nogales. Ariz. The troops are at the border to deter crossers and report them to the Border Patrol.
The National Guard force that President Bush called up to help secure the U.S.-Mexico border is now been fully deployed or in training. But even before those troops arrived, the Border Patrol reports that the number of apprehensions of illegal border crossers this July was down from last July's arrest count.
