January 17, 1984: Port Authority Terrorist Intelligence Unit Issues Report on WTC Security

Detective Sergeant Peter Caram, the head of the New York Port Authority’s Terrorist Intelligence Unit, has been directed by the assistant superintendent of the Port Authority Police Department to compile a report on the vulnerability of the WTC to a terrorist attack. Having previously worked at the WTC Command, Caram has exclusive knowledge of some of the center’s security weaknesses. On this day he issues his four-page report, titled “Terrorist Threat and Targeting Assessment: World Trade Center.” It looks at the reasoning behind why the WTC might be singled out for attack, and identifies three areas of particular vulnerability: the perimeter of the WTC complex, the truck dock entrance, and the subgrade area (the lower floors below ground level). Caram specifically mentions that terrorists could use a car bomb in the subgrade area—a situation similar to what occurs in the 1993 bombing (see February 26, 1993). [Caram, 2001, pp. 5, 84-85; New York County Supreme Court, 1/20/2004] This is the first of several reports during the 1980s, identifying the WTC as a potential terrorist target.
