Migrants traveling in caravans toward the United States have generated plenty of headlines, especially as events unfold at ground zero -- the U.S.-Mexico border. What is really happening there is the focus of this series, a documentation of the work of law enforcement on the border, from Nogales, Ariz., in the west to the Rio Grande Valley and points east. CNN correspondent Bill Weir engages with experts across a range of border issues, offering insight and perspective on events as they happen. Also, investigative journalist Lilia Luciano is immersed in the field and tackles stories by interviewing people who live and work along the border.
