Call me a skeptic, but I am not comvinced binladen was who was killed. The GOV certainly has the capacity to cook up a scenario to benefit itself.
And a chopper full of SEALs died shortly thereafter. Were they the seals that knew too much? Likely. When the news of their demise first came out it was reported that they were the same SEALs that had been involved in the Osama bin Laden operation. Shortly thereafter it was reported that they were not. Which one was it? I would guess that the first account was true and then "sanitized" to not let the public think that their untimely deaths were a bit too peculiar. What the facts really are, few can tell.
