Even if it were true, what could it mean? I've read that there was some slop with the investigation, but they got McVeigh with a motive, a means, and a link to the crime scene. If this video was shot on the day of the bombing, and it was verified by more than one expert (Dr. Blomgren is a speech pathologist, not a forensic scientist in this area), then it would be something.
