In 2006, Walsh and Anticev’s squad squelched a plot to destroy a Hudson River retaining wall in downtown Manhattan. The suspects, located overseas and inspired by a story on 60 Minutes about the wall’s vulnerability, used the Internet to research the use of explosives, to gather maps of lower Manhattan and the subway system, and to organize individuals for the attack. The FBI monitored the chat rooms in which the plan was unveiled, and used its international network of law enforcement and other agencies to identify the people behind the screen names.
