There were reports that Atta's boys 'blended in' so well that they took to eating pork and playing bouncy-bouncy with the whores.
I have no doubt that diddling whores (and goats and young boys, for that matter) comes naturally enough to a 'devout moslem', but eating pork normally doesn't.
But they'll do ANYTHING if it serves their larger agenda.
a moslem is a born liar, commissioned by his gutter cult to sow confusion among their enemies by playing fast and loose with the truth.
Hell, their 'god' was a blasphemer. The Bible records him saying, "I will be like the Most High..."
I think it is more likely that the bombers were simply hypocrites who were doing what they were doing more out of nationalism than religious devotion.
