I think there might have been some legitimate data presented for testing, but because of errors, misrepresentations, misinterpretations, and little or no chain of custody I have my own personal doubts about any of it being salvageable.
Humans do make mistakes and that's fair. Unfortunately Ketchum's modus operandi has been to make a mistake and then attempt to cover it, only to make another mistake in the process, rather than just owning the mistake and attempting to correct it. A lot of patience and good faith has been burned up because of this.
