DougR, in answer to your question...
I guess it would depend on what you are trying to accomplish. If you are trying to make the US and the world safer from terrorism, my opinion is that we need the help of the Arab world and the Muslim world. So if they find Bin Laden innocent, but at the same time, help us to root out and eliminate the massive webs of terrorist organizations, and also help us to render people like Bin Laden unable to cause harm, then I would endorse their actions.
If what we are trying to accomplish is to try to maintain this illusion we as a nation seem to have, that we are superior to the rest of the world, that we are invincible, that we don't need anyone's help, and that we will, by golly, show those bastards that they can't mess with us, then I'm afraid nothing will help us. Whether Bin Laden is brought to justice or not.
So, I am in favor of whatever will help promote the goal of making the world safer for all of us. Whether that includes the elimination of Bin Laden, or not.
