After looking at Dr Shneour's credentials on the internet, and confirming with Bill Troop that this was indeed the same person, I come to the conclusion that he is indeed a respected individual in US chemistry circles with good credentials. I also find that Bill, at no point, said that Shenour was associated with Agfa.

Therefore, Doctor Shneour's comments may be considered entirely valid as given to Bill in an interview. Any comments to the contrary may be irellevant. Dr. Shneour has been free to comment since the publication of the original FDC and has not done so and therefore I consider the matter closed as stands in Bill's comments.
