The loss of that helicopter was never blamed on a YouTube video. I agree that not all attacks can be prevented and that some attacks result in loss of life. What I don't understand is why the administration concocted a huge lie that wasn't convincing to anyone (except the disinterested mainstream press) to cover up the incident. It's the Secretary of State's job to safeguard the lives of the thousands of diplomats that are posted all over the world. She should have shown the most concern about the cause of the attack in order to prevent future events like it.
