CNN tapes "coyotes" as migrants cross into the US | Video

These are extraordinary images from Ciudad Juárez, Mexico. A city across the border from El Paso, Texas. CNN correspondent Matt Rivers and his team followed human traffickers, also called "polleros" or "coyotes." They managed to record the moment when two immigrants were illegally brought into the United States. It is a video that is rarely seen from this perspective, from the immigrant's point of view. Human trafficking is, of course, a crime, but we wanted to document this process because it is part of the reality of what happens at the border every day. And what can be lost among the numbers is exactly how so many immigrants get here, using human trafficking. It can be a terribly dangerous journey that hundreds of thousands of people are still willing to take,desperate to get to the United States.
