Presenter Mike Angley The USA Patriot Act: 13 Years Later, the next webinar in the Henley-Putnam webinar series. In the webinar, Mr. Angley presented information about the Patriot Act, the principal legislative response to the events of 11 September 2001. The Act substantially changed a number of national security legal authorities available to law enforcement (LE), counterintelligence (CI) and counterterrorism (CT) operators. The Act’s improvements to operational authorities, including the Foreign Intelligence Surveillance Act (FISA), make these tools more flexible and more readily available to security professionals. The removal of legal obstacles to the sharing of information between law enforcement and intelligence components should enable a better response to nontraditional security threats. The established trend toward the harmonization of legal authorities across disciplines and the coordination of strategy will, if properly exploited, work to the benefit of the security mission.
