Arizona's border tighter, arrests down, but at a cost
"Two fences - one concrete to block cars, the other barbed wire to block people - cut through a wide valley in the Tohono O'odham Nation Reservation west of Tucson. Ground sensors and infrared night-vision cameras scan the vast terrain. Teams of Border Patrol agents comb dirt and concrete roads, perch at roadside checkpoints and search the Sonoran Desert by air and ATV. Welcome to the nation's busiest border and epicenter of the U.S. immigration debate."
