As elated crowds celebrated the death of Osama bin Laden after Navy SEALs killed the al-Qaida chief in a weekend raid in Pakistan some are asking, Where's the proof?" Photos depicting a bloodied and bruised face appearing to be that of bin Laden began appearing on Twitter and Facebook last night soon after news of his death spread across the Internet. According to Reuters, an archive photo of bin Laden at a news conference proves that image was a fake. Now people are asking to see the evidence proving bin Laden is dead. From Pakistan to the U.S. people expressed their skepticism about the death of the man who is perhaps the most infamous terrorist ever known. Officials said today they are "99.9 percent" certain that bin Laden was shot dead in Pakistan. They also cited CIA photo analysis matching physical features such as bin Laden's height. Rep. Mike Roger, chairman of the House Intelligence Committee, told the Associated Press that more than one DNA sample was used to identify Osama bin Laden. After Adolf Hitler's suicide in April 1945, conspiracy theories for years suggested Hitler was alive and in hiding. The Russian secret services came forward with a skull and jawbones. DNA results eventually showed the skull was that of a female.
