NYPD must have the ability to disrupt cell phone calls in the event of another planned attack on New York City. Homeland Security says the NYPD believes the Mumbai attacks could be a model for other set of low-tech attacks. It was not clear whether the NYPD has the means to disrupt electronic communications for a small group of terrorists without shutting down cell phone service to a large part of New York City. The terrorists had handlers who used cell phones and other portable communication devices to order the killing of hostages and adjust tactics during the siege of Mumbai. The 10 attackers, who Indian authorities say came from Pakistan, fanned out to locations such as hotels and buildings, taking and executing hostages and holding off Indian security forces for several days. The attacks left more than 170 people dead and some 300 wounded.

Drawing lessons from Mumbai terror attacks, New York City Police Commissioner, Raymond Kelly said he is looking into technologies that can disrupt cell phones and other communication devices of the terrorists in a pinpointed manner at the time of such attacks.
