Time reports that the FBI has sent a bulletin to law enforcement agencies, warning that individual suicide bombers may attempt to strike inside the United States.
Law enforcement professionals should be on the alert for “people wearing heavy, bulky jackets on warm days, smelling of chemicals, trailing wires from their jackets” and should know that “suicide bombers may disguise themselves in stolen military, police or firefighter’s garb, or even as pregnant women.”
Note the last paragraph:
In fact, U.S. analysts are at a loss to explain why the homeland has thus far escaped such attacks, since a number of extremist groups, particularly Hamas, have a sizeable presence here. One factor, officials say, is that terror leaders still regard America as a cash cow, and don’t want to antagonize moderate Muslim donors. Another reason, says one specialist, may simply be that while there seems to be an endless supply of fanatical youths willing to die for the cause in the Middle East, most of them simply can’t get visas to the U.S.
