A U.S. intelligence bulletin warned today that the violent outrage aimed at U.S. embassies  spawned by a movie mocking the Prophet Mohammed could be spread to America by extremist groups eager to “exploit anger.”
The Joint Intelligence Bulletin issued by the FBI and the Department of Homeland Security said “the risk of violence could increase both at home and abroad as the film continues to gain attention.”
“First responders should remain aware of the potential for spontaneous large crowds and protests that could overwhelm resources and should be vigilant for possible efforts to encourage peaceful protesters to commit acts of violence,” the warning said.
It urged “faith-based organizations to promptly report suspicious activities that could indicate pre-operational plotting against Jewish, Coptic, Islamic, or any other faith-based communities.”
