Established in the wake of September 11, the Department of Homeland Security (DHS) was entrusted with protecting the U.S. from national security threats. Since then, much of the agency’s focus has been on the southern border — with tens of thousands of people held in its detention centers on a daily basis. Host Maren Machles explores how this came to be and delves into what happens to people held in immigration detention centers with the presumption that they may be national security threats. And she asks the question: How does this relate to the way DHS addresses the most dangerous threat currently facing our nation — far-right violent extremism?

To find out, Maren talks with Daryl Johnson, who recounts his work as the former lead analyst for domestic terrorism at DHS. She also speaks with Alejandro Beutel, a criminologist who focuses on domestic terrorism, and Berto Hernandez, who shares their story of being brought into the U.S. as a child and held in detention by Immigration and Customs Enforcement years later.
