The 'jubilant' celebration of the 'attackers' at finding Stevens STILL ALIVE comes damn close to be 'conclusive evidence' of the kidnapping - but NOT of obama's ties to it.
The complete 'set up' of Stevens, hanging him out to dry, the June 6th attack, the TOTAL LACK of any response during the ACTUAL ATTACK (which we now know they even had a drone watching ti) .... DOES provide the conclusive circumstantial evidence.
I would really hate to be a defense attourney attempting to argue the 'innocence of obama and lack of kidnap plot' given these already known facts, and a decent prosecutor.
Just my take - of course. *s*

Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good ...
