Was Tillman Murdered?

That is a possibility MSNBC is reporting tonight:

The investigation must be reopened now. Considering there were calls from the military to the White House regarding the death, then the investigation must be fully opened to the White House. Executive privilege can not be used to cover up a possible murder either. If this is found to be true then anyone involved deserves the same fate Saddam had - and I don't care if it's George Bush.
