Questions Over Border Stops Inside the Border

(05/03/05) The U.S. Border Patrol has dramatically increased the use of road checkpoints inside the U.S.- Canada border. One on the Adirondack Northway grabbed headlines last year after 4 people died and more than 50 were seriously injured in accidents there. But there are also dozens of border patrol checkpoints on smaller roads across the North Country. The Border Patrol says they're a critical second line of defense for stopping terrorism. But some citizens and civil liberties groups say they're an invasion of privacy and may not be very effective. David Sommerstein reports.
