....but since you brought it up.....
Did you know that when the sample (again, taken from the ONE spot on the Shroud that the team insisted should be avoided? curious as to why?) was tested that there were only about 11 facilities in the world capable of radiocarbon dating? Did you also realize that there were ZERO standards among these labs/test facilities? Zip.....nada.......zilch? Do you not agree that calibration to agreed-upon standards would be a pretty good idea (ahem)?
Are you also familiar with the factors that determine results from radiocarbon dating?
It isn't that it "doesn't work". It also isn't bloody magic, either.
You're making an accusation of fraud.
