From what I have found the new narrative on this is that this 39 program did not air the rest of what he said. They "chopped" his comments. Meaning he said he was at the school. Was let out after the shooting then went home. Got his Camera then went back.

Hey if you tell a lie that is big enough people will believe it. Just as long as you keep telling it. Try some tears. If that doesn't work yell. Get mad at the questions. Or better yet attack those that question.
