Factual error: A computer screen is used to show that a matching record was found for the fingerprint of one of the terrorists. But the two prints shown are identical, meaning they are the same print, shown twice. In reality, a matching print would show the same patterns of skin texture, but the ink pattern, record quality, angle of the finger to the paper, would all vary. You can't make the exact same finger print twice. It's similar to you signature - it's always extremely similar, but never precisely the same. (00:31:40)
