They were prepping for a second larger wave, and were waiting for the signal to do so. The FBI putting the pictures up triggered them to go earlier. The amount of firepower and IED’s in their possession gives evidence to a second larger strike. I am assuming a suicide attack either on one of the campuses, or on mass transit.
Wasn’t the Beslan massacre committed by Chechen muslim jihadis?
How about that attack on the Greyhound bus driver by the Croatian guy back in October of 2001? Could he have been Chechen or a Kosovar Muslim?
