Via eavesdropping, terror suspects nabbed

Counterterrorism officials from the US FBI, CIA, and Treasury Department, as well as law enforcement officers from other countries involved in the war on terrorism, are using sophisticated, high-tech methods to track suspected terrorists by monitoring their cell phone communications, and using these communications to determine a person's physical location. While these methods are not always successful, they have enabled law enforcement officials to prevent several terrorist attacks around the world and arrest dozens of suspected terrorists. In fact, Khalid Sheikh Mohammed, who was instrumental in planning the 9/11 terrorist attacks, was arrested in Pakistan in March 2003 by tracking his cell phone's SIM (Subscriber Identity Model) card.
