Evaluating Intelligence and Information Sharing Networks: Examples from a Study of the National Network of Fusion Centers

October 01, 2015

In the weeks and months following the 2013 Boston Marathon bombing, Congress and the media asked why the intelligence and law enforcement communities had failed to intercept the Tsarnaev brothers, who were known to the Federal Bureau of Investigation (FBI) prior to the attack.

Terrorist organizations including ISIS, Hezbollah, and al‐Qa’ida have openly promulgated a strategy of ecological jihad. In contrast to other methods employed by terrorists, environmental tactics, such as contaminating water supplies or starting fires, can be quickly planned, require little technical expertise to execute, and have lower risk of detection. Water shortages due to drought increase vulnerability to these terror methods with significant consequences for people, infrastructure, and the economy.
