El Salvador imprisons citizens of several countries in crackdown on crime

El Salvador has cracked down on gang violence in the past year by hauling tens of thousands of people to jail. Citizens of other countries, including the US, Colombia and Guatemala, have been caught up in the sweeps and imprisoned, often without due process. Manuel Rueda reports on some who say they were wrongly imprisoned for months, just because they have tattoos or were in the wrong place at the wrong time.
