multiple hits with guided bombs would do the same job but US opted to use the black-ops to make sure they had a body to photograph,dice,slice,etc and show to tax-paying Americans where their money was spent : retribution.
it will be media's folly if they publish that OBL died in a blaze of glory as this will guarantee his martyrdom.
only the complete destruction of limb,life,reputation, even the myth that surrounds OBL will shatter the confidence of his followers.
