I saw it and was the last to respond to the thread before it was yanked (I must admit, my response violated the posting guidelines big-time). However, al Qaeda also has been reduced to taking credit for actions they could not have caused (such as that plane crash on Mt. Kenya), so I really don't know what to make of this. I think there is a better chance that this is meant as an empty threat than the chance that this is a precursor to any kind of domestic terror action.
