What about Bush’s zero-tolerance zones?
In 2005, President George W. Bush’s administration introduced Operation Streamline at the border crossing in the Texas city of Del Rio. The program eventually expanded to more border sectors.
The goal of the program was to refer unauthorized border-crossers for prosecution, but families with children were exempted from enforcement.
“The Border Patrol, as a matter of policy, does not refer for prosecution juveniles, parents traveling with minor children, certain persons with health conditions, and others who require prompt return to their country of origin for humanitarian reasons,” reads a report about the program issued by The Chief Justice Earl Warren Institute on Race, Ethnicity and Diversity at the University of California, Berkeley.
