I am sure it is relevant in that they were most likely given a directive to kill him, or at least this was more than implied from higher. However, these guys routinely go into houses to kill or capture HVTs and often capture, instead of kill.
I can guarantee that if the directive was to capture and only kill if they have no other option, an unarmed bin Laden would have been taken alive.
why are we putting our guys at risk just so bin laden has the option of giving himself up? the safety of those men is #1.
