Salvadorean migrants run to jump on a train to the border with the United States, in Lecheria, 30 km north of Mexico City, on June 1, 2010.
Crossing the border into the U.S. without proper documentation is against the law. And as we know, there is plenty of security in place to arrest and deport those who break that law.
The immigration reform bill passed in the Senate would create significantly more security if it goes anywhere, but a new study from USC and Stanford finds that the threat of arrest and punishment is still not a deterrent for people to cross the border illegally.
Emily Ryo, a USC law professor and research fellow at Stanford who authored the study, joins the show to explain her findings.
