Heard on NPR news this morning: The FBI has notified several local law enforcement agencies that Al-Qaeda may be planning an attack to cause "spectacular damage" to the US economy. However, they didn't know the time or location of the attack, nor what form it would take.
Hate to tell you, but we already knew they had it in for us.
In related news, the FBI also mentioned there would be tornados, sleet, and hail somewhere over the US, sometime before next summer. When pressed for details, they added, "50% chance it'll be west of the Mississippi".
