What unique capabilities does HSI bring to national security threats?

The unique capabilities that HSI (Homeland Security Investigations) brings to addressing national security threats are rooted in its specialized law enforcement authorities and access to a variety of crucial information resources. One of these significant capabilities is its access to databases and border search authorities. This allows HSI agents to effectively gather intelligence and investigate threats that span across borders, which is essential in today’s interconnected world.

HSI's access to databases enables agents to track criminal activities and potential threats by having comprehensive information on individuals, entities, and transactions that may pose risks to national security. Moreover, the border search authorities allow HSI to conduct searches and seizures at U.S. borders and other checkpoints, facilitating the interception of illegal goods and individuals before they can enter the country. This dual capability of intelligence-gathering and enforcement is critical for proactively addressing and mitigating potential national security threats.

The other options refer to capabilities that do not uniquely define HSI's role. While direct involvement in international diplomacy is generally reserved for diplomatic entities, or coordination with state and local law enforcement may be more collaborative and broadly shared among various agencies, HSI's specific mandate for forensic and investigative work regarding national security threats underlines the importance of its specialized access and authority.
