Before I get into the details of the procedural problems, I want to note not one particular group involved bears all the guilt, but all groups involved in the C-14 dating bears responsibility. Some even might have good reasons to introduce procedural violations. But for the most part, they should’ve known better.
I would say the TS C-14 dating would be one of the most high profile C-14 dating projects. Everyone involved should have taken the utmost care and rigor in conducting the test. But, as I will argue, they did not.
Probably the only major group that is innocent in all of this would be the original STURP team. And that’s only because they were unceremoniously kicked out to have any involvement with the C-14 dating. In hindsight, it turned out to be a blessing to them to not have been involved.
