Not very much at all, though one might think "buried" has some ritual attached as opposed to "tossed overboard".
But, if as the Pres claimed, they have been hunting OBL for 10 years and finally shot him in the head, why would they consign their trophy to the deep never to be seen again.
Yet the crowd loved it.
And markets rallied.
And gold/silver fell dramatically.
And all of the commonfolk are now focussed on and rejoicing in OBL's demise.
