This was a BlackOp. Why else were they using SEAL Team 6 (a team that supposedly didn't exist) and modified Blackhawks (that also supposedly didn't exist) unless this was a capture and go? A regular SEAL team and regular Blackhawks would have worked for a kill mission.
They left plenty of people alive in the compound, surely if this was a kill mission they'd all be dead so that no-one could point the finger back to the US. Plausible deniability.
If this was a kill mission, why would they have Chinooks? All the team, plus Bin Laden's corpse managed to fit in a single modified Blackhawk. Chinooks would have been unnecessary and even extremely risky given the small size of the LZ.
I'm willing to bet that the original plan was to capture everyone in the compound, including Bin Laden. I suspect that killing Bin Laden was the last thing they wanted to do. Yes, the US and most of the world has celebrated. But now they have effectively martyred Bin Laden and plenty of Muslim fundamentalists are now planning a retaliation. If this had been a covert capture, Bin Laden wouldn't have been martyred, they would have senior al-Quaeda captives to interrogate and there would be no rallying point for fundamentalists to retaliate.
Yes, I agree it would have been a three ring circus if Bin Laden had been publicly captured. The public would have demanded his execution, and he would have been martyred anyway. However, if he had been covertly captured he would just have disappeared into a CIA holding facility, and the world would know nothing. At some point, when it is most convenient for the Administration, his capture could have then been made public.
This mission was never a public mission. It was a BlackOp. They just fcuked it up.
