Although New York City officials never received information about a possible attack on the World Trade Center from the White House, the intelligence might not have changed the city’s counter-terrorism security measures, former mayor Rudolph Giuliani told the Sept. 11 commission.
Giuliani said the information he did receive in intelligence briefings from federal officials focused on New York’s bridges, tunnels, and subways as likely targets. He also indicated that the security precautions that were taken anticipated suicide bombings rather than “aerial attacks.”
