This thought-provoking book examines gang history in the region encompassing West Texas, Southern New Mexico, and Northern Chihuahua, Mexico. Known as the El Paso-Juárez borderland region, the area contains more than three million people spanning 130 miles from east to west. From the badlands--the historically notorious eastern Valle de Juárez--to the Puerto Palomas port of entry at Columbus, New Mexico, this area has become more militarized and politicized than ever before. Mike Tapia examines this region by exploring a century of historical developments through a criminological lens and by studying the diverse subcultures on both sides of the law.
