The American Civil Liberties Union reported Wednesday Jan. 15, 2014 that border patrol agents at checkpoints across southern Arizona are routinely violating the constitutional rights of U.S. residents, including unjustified detentions and illegal searches as a pretext to investigating other criminal activity in violation of the agency's mandate that stops be limited to inquiring about citizenship and visually inspecting vehicles.
