"Three facts about the Constitution-Free Zone: Fact 1: In the "Constitution-free zone," Border Patrol agents don't need a warrant or probable cause to conduct a "routine search." All travelers crossing a border are assigned a risk assessment score that will be retained for 40 years. Fact 2: The Border Patrol can put a checkpoint anywhere in the Constitution-free zone (think Fifth Avenue!). "One hundred air miles is still, technically, the border," says Leslie Lawson from the Nogales Border Patrol Station. Everyone at a checkpoint must answer questions about citizenship status. Fact 3: The Constitution-free zone extends 100 miles from any U.S. border. Two-thirds of the U.S. population (197.4 million in 2008) lives within this zone, which includes nine of the 10 largest metropolitan areas, and the entire populations of: Connecticut, Delaware, Washington, D.C., Florida, Hawaii, Maine, Massachusetts, Michigan, New Hampshire, New Jersey and Rhode Island; and over 90 percent of: California, Maryland, New York, Vermont and Washington." - David Bacon, June 2014.
