Ron Paul criticizes Obama for drone killing of Awlaki

Awlaki's lectures on Islamic scripture were cited as inspirational by Maj. Nidal Malik Hasan, the Army psychiatrist charged in the 2009 Fort Hood shootings, and Faisal Shahzad, who tried to set off a car bomb in Times Square last year. But Paul said it was unclear whether Awlaki had ever been directly responsible for a terrorist killing, and compared him to Oklahoma City bomber Timothy McVeigh.

"We didn't assassinate him, who — certainly he had done it. Went and put through the courts then executed him. To start assassinating American citizens without charges, we should think very seriously about this," Paul said.

Paul said that the killing of Awlaki was different from that of other terrorist leaders, like 9/11 mastermind Osama bin Laden.

"Not exactly. Because he was involved in 9/11 and I voted for authority to go after those individuals responsible for 9/11. Al-Awlaki — nobody ever suggested that he was a participant in 9/11," Paul said.
