I think the question before this august body is: was this banner produced on a moment's notice? I have not heard any persuaive argument that it was "impossible", it does appear to be unlikely.
Certainly, Hezbollah has shown that they would not scruple at doing something like this.
Some have suggested that the dead were actually transported from a morgue in Tyre and that there appeared to be very little recovery activity. The "rescuers" do seem to be making more effort at displaying corpses than rending aid. Also the bodies do not appear to be fresh.
I wonder why there aren't any injured. Usually in a building collapse there appear to be about as many nonfatal injuries as fatal. All the victims on offer are dead, Jim. Where are the ones with broken arms or serious internal injuries, where are the walking wounded?
My BS meter is pegged.
She had a planned visit, is there anything about the poster particular to the bombing is the question I suppose. (Along with the logistics if there is).
The answer is the large part of the banner probably was prepared beforehand. The real question is could the bottom have been added in a short time. As an accountant who prepared numerous documents using scissors, white-out and transparent tape back before Word and modern printers, I would not be ready to say a previous prepared poster could not be modified. I would be more persuaded if the area mentioning Qana were the large part.
