Well I don't know the answer. Is the video being shot by Kerry's 'cameraman' what we are seeing on TV? If so, some arrangements with the media were made to get this feed to them. This doesn't happen without planning and arrangements being made. Maybe the media was in on this photo-op?
If you'd heard the nauseating excuse-making MSNBC was making for him, you wouldn't need to ask that question.
He came in with a separate cameraman.
