Certainly Biometrics could establish his innocence, even if it could not necessarily establish his guilt. But I doubt that the "journalists" in the MSM will bother to go to that much trouble. The only "hard-liners" they worry about are in the Bush Administation, and they wouldn't want to give them any ammunition that might justify a confrontational approach to this guy.
He's probably the same guy. However, how on earth will biometrics do anything? Do you think you're going to get a fingerprint from the guy in the photo from the 70's? Retinal scan?
