While it may offend some, the simple truth is Obama would have been a huge liability as a living prisoner. His imprisonment would have been a rallying point for his followers. There would have been countless terrorist attacks and hostages taken to try to pressure the U.S. into releasing him, Frankly, even if we did capture him, we'd want to claim we killed him just to minimize retaliation.
I've warned you for the last time. Stop making sense in P&N.

Heh, just kidding-
To be sure you are correct, however let's do a thought experiment.
LL, I'm going to set the stage here so we have something besides "should or should not have"
You are in charge of the mission and are given latitude to make the decision to take Bin Laden alive or shoot him depending on the situation. Let's further assume that you are a professional and not driven by revenge, however leaving him alive is not one of your options.
In this scenario Bin Laden is in fact unarmed. At first look it's a simple matter. Seize and remove. Unfortunately that's not simple.
OBL isn't sitting in an isolated environment. Let's consider where he is. He is located in a heavily guarded building which isn't easily accessible. Further he is sitting in a militarized zone controlled by the ISI. Think Quantico.
You have one way of accomplishing the mission and that is to get in and out fast. If you do not the mission fails and you and your men die.
You have 20 seconds, perhaps a minute before mission failure.
How do you get Bin Laden out alive?
