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.
