Traveller is a pisser! He always seems to throw in an unsuspected, underhanded rank-out of us at the close of his posts.
I, for one, do not know the validity of what he says. I do know that I have read one or two translated posts at IH in the recent past (early last summer?) where jihadis were discussing overall attack date preferences and they seemed to be saying that Tuesdays were the best but Thursdays were ok as backups, so to speak. Soon after there was a Thursday attack. I cannot remember which attack it was or when it took place though. But it was a Thursday. May have been the first Saudi Arabian attacks.
LOL! I'm not sure of the validity either, just found the Tuesday reference to a historical event interesting and pausible.
