Labelling the 26/11 terror attacks as deceptively simple and highly coordinated with little money expended, the FBI has said the crippling flaw in the Mumbai police's defence against the initial assault was that its officers didn't even carry weapons. The premier US investigative agency has also pointed out that the Indian forces did not have the sophisticated gadgets and systems to intercept the communication between the attackers and their handlers in Pakistan. FBI said absence of weapons with the Mumbai police had led to dozens of people being mowed down at five-star hotels, a train station and a Jewish centre before the specialised Indian forces killed all but one of the terrorists. FBI's Supervisory Special Agent Anthony Tindall told members of the agency's Joint Terrorism Task Force in Washington that in the US, authorities would bring guns and bullets much quicker than the Indians could have. Tindall, now based in Hawaii as the FBI's liaison to the US Pacific Command, said India sought the FBI's help during the November 26-28 attack and the bureau deployed eight agents from Los Angeles as well as technicians from Quantico, Virginia. He said FBI gained the trust of Indian investigators almost immediately because its agents and technicians were able to glean significant information from GPS, cellphones, satellite phones, Internet data, financial records, witnesses and boats used by the terrorists.
