As of Dec. 20, the very same instructions that Akayed Ullah used to learn how to build the bomb he detonated in the New York subway attack on Dec. 11 allegedly remains online and available to clever terrorists able to find them. That, along with numerous other clearly stated threats from terror groups to U.S. aviation, rail and other surface transportation systems, commands a growing amount of precious time from Transportation Security Administration officials, who are working day and night to stay ahead of the threat. Stacey Fitzmaurice, deputy assistant administrator at the TSA’s Office of Security Operations, and Bob Melan, a security specialist at the surface division of the Office of Security Policy and Industry Engagement, sat down with Target USA to lay out the threat, some of their counter measures, and how it all impacts TSA’s plans to protect the traveling public. Also, Philip Mudd, former CIA and FBI executive, explains what the latest terrorist tactics mean for the future.
