U.S. Customs and Border Protection says that it has established "effective control" of 293 miles of the 378-mile-long Arizona-Mexico border and that all of the 85 miles that are not under "effective control" are in the Tucson Sector, where about half of all illegal entries into the United States took place in fiscal 2010.
