I think there's something amiss with Bin Laden not appearing in a video for the 9/11 anniversary. Either he's dead or he's about to commit some other heinous act and is waiting until afterward to crow about it on a video.
I don't like the sound of this alert in Israel. Their intelligence is usually very good.
I think he was killed at Tora Bora....remember, he has not been seen on video since Nov 2001 when they were discussing the falling towers...
