Terrorism is not new to New York, with one of the first documented cases dating back to 1920 when a horse-drawn wagon filled with dynamite was detonated on Wall Street, killing dozens and injuring hundreds more, Ingram said.
Ingram said the Fuerzas Armadas de Liberación Nacional (FALN), a clandestine Puerto Rican paramilitary organization, was responsible for 49 bomb attacks in New York City between 1974 and 1979. And there have been other attacks, including one on the World Trade Center in 1993.
"Terrorism is nothing new, but there are some things we have to do to adapt and be prepared for it," Ingram said.
As part of that preparation, the department developed the FDNY Center for Terrorism and Disaster Preparedness which developed a response strategy and has become the agency to receive confidential information and intelligence to help determine responses.
