There is no mention in the transcript of the muslim DC snipers. Laden's trying to rally the troops including the lone operators.
He did mention Chenians (but there aren't many details).
He didn't mention the political elections here or abroad or any American vote to pound Iraq.
Difficult to date such rhetoric without him providing concrete specifics. I'm sure that Al-Quaeda had a number of attacks planned and sleeper cells ready to operate.
Why the cover? Why not a video? Is someone going to recognize the room? Paint Saddam's bathroom walls black, that ought to disguise it...
