That's what you were supposed to hear. Problem is, I didn't see him say it. Every time he's saying the admissions to treason, the camera changes to a wide shot where you can't see his lips moving, or his back is to the camera. Why? Cutting and splicing the audio track is a lot easier than modifying several seconds of video in an undetectable manner. Also, it's clear that the video was taken professionally: multiple cameras, smooth cuts from one to another, cameras operating in concert, and... the president's speaking directly into a microphone. Why is the video so good and the audio so poor? Because after hacking up the video cuts and after cutting, splicing, and processing the video to make the Obamanation's speech sound like a confession, it's still too easy to detect the edit job. Degrading the quality of the audio makes it harder for a technician to detect the audio-video mismatches and the pulling in of audio from other sources and what-not.
tl;dr: I'm with tcox4freedom on this.
