Description:

As global illicit trade networks become increasingly sophisticated and the corresponding risk of sanctions evasion increases, so has the law enforcement response to deal with these threats to national and global security.

Join subject matter experts from the Department of Homeland Security for a look at sanctions enforcement as seen through the eyes of federal law enforcement.  This session will present real-world investigative examples of sanctions evasion by transnational criminal organizations who seek to exploit international financial and trade systems, while highlighting some law enforcement mechanisms and tools utilized to combat this threat.

Webinar participants will gain insight into the importance of law enforcement partnerships with financial and industry counterparts to detect, investigate, and disrupt complex illicit networks.

Key Takeaways:

  • How sanctions can be an important tool in the law enforcement toolbox.
  • How law enforcement partnerships with private industry and financial institutions are a key tool in investigating sanctions evasion.
  • Understanding that prompt responses to red flag indicators is vital in addressing the threat.
  • Some of the lessons learned from significant HSI investigations.
