Since Aug. 29, four vehicles have crashed on Interstate 10 between Tucson and Benson. Those wrecks alone left four migrants dead and 29 injured. Another six died in previous crashes and 102 more were injured. They say they have little power to stop the vehicles, and they have had little luck arresting those responsible. In Chicago, the number of agencies has nearly doubled since 1985 to more than 200.
Some agencies even ask workers to sign waivers in case they have an injury on the job.
With unemployment close to a 30-year low of 4 percent, employers are hungry for workers.
