Homeland Security Investigations

Homeland Security Investigations (HSI) is a division of the Department of Homeland Security (DHS) responsible for enforcing immigration and customs laws within the United States. HSI is in the news recently due to several incidents. First, newly released records revealed that an HSI agent shot and killed a US citizen in Texas last year during a traffic stop, an event that was not publicly disclosed. Second, a federal immigration supervisor has been charged with harboring an undocumented person, allegedly his girlfriend, who may also be his niece. Finally, HSI agents are slated to have a security role in the upcoming Milan-Cortina Winter Olympics in Italy. These events highlight the agency's broad scope, from domestic law enforcement activities with potentially deadly consequences to international security cooperation, while also raising questions about accountability and ethical conduct within the agency.
