Organized Crime and Terror Related Investigators who pieced together the puzzle of the March 2004 Madrid train bombing that killed 191 and injured some 2,000 found that the Islamic extremists suspected in the attacks had funded their jihad in a not-so-holy way: they traded hashish and ecstasy for 440 pounds of dynamite, then drank holy water from Mecca to assuage their guilt. Experts say that one way to break into terror networks is through their financing.
