Unfortunately there is no way we (CIA) can
provide evidence that OBL was actually killed. We cannot provide
a corpse that can be tested for DNA, (because he is alive? And
hidden
maybe in Fort Knox?). We cannot provide a witness to his
death (because he isn't dead?). Unfortunately we had to kill one
of
his wives/concubines. If she hadn't been killed we would have had
to take her with us, and that was not a plausible scenario. We
cannot even provide (faked?) photographs because sooner
or later technology would improve and would be able to prove that they
were faked.
We have
to try to divert attention from the "OBL is alive and captured"
scenario. Hence burial at sea. We must lie to the
president, or tell the president to lie to the US people ?) and the
world.
