The compound is, of course, now gone, so it is no longer possible to reconstruct what happened the night of the raid based on forensic evidence, although it is possible the Abbottabad Commission, a panel that was appointed by the Pakistani government to look into the raid, could shed some light on this question should its findings ever be publicly released.
Finally, by all accounts, it was a confusing situation the night of the raid. One of the SEAL team's helicopters had crashed and there was a firefight with one of bin Laden's bodyguards. All the electricity in the compound and the surrounding neighborhood was off on a moonless night and the SEALs were all wearing night vision goggles, which only allowed them limited vision.
What seems incontrovertible is that the point man, the Shooter and Bissonnette were the first three SEALs to assault bin Laden's bedroom. But to determine exactly which of them killed the al Qaeda leader may never be possible.
What is certain is that it was a team effort.
Five days after the bin Laden raid, members of the SEAL team who carried out the mission briefed President Barack Obama. According to those in the room, the SEAL team commander explained to the president, "If you took one person out of the puzzle, we wouldn't have the competence to do the job we did; everybody's vital. It's not about the guy who pulled the trigger to kill bin Laden, it's about what we all did together."
