A terrorist cell usually forms very quietly and then grows in a pattern ¿ sp- ning international borders, oceans, and hemispheres. Surprising to many, an eff- tive ¿weapon¿, just as quiet ¿ mathematics ¿ can serve as a powerful tool to combat terrorism, providing the ability to connect the dots and reveal the organizational pattern of something so sinister. The events of 9/11 instantly changed perceptions of the wordsterrorist andn- work, especially in the United States. The international community was confronted with the need to tackle a threat which was not con?ned to a discreet physical - cation. This is a particular challenge to the standard instruments for projecting the legal authority of states and their power to uphold public safety. As demonstrated by the events of the 9/11 attack, we know that terrorist attacks can happen anywhere.
