First report was Bin Laden was armed and using his wife as shield. Just 24 hours later Obama Administration is saying Bin Laden was unarmed and had no shield. Remember Bin Laden said he would never be taken alive. If he won't surrender, gun or not, then shoot him.
Everything that happened during the attack was watched at the Whitehouse through the use of helmet cameras by the Navy Seals. Maybe before telling the press anything they should verify what they saw on the helmet cameras.
