The "flawed C-14 tests were accurate. They were taken under a very strict protocol and under direct observation of the Vatican and experts in carbon dating. Rogers received a specimen that was allegedly from the shroud without any protocol whatsoever. The original scientists stand by their results. If Rogers wants to prove them wrong, he will have to do another C-14 test. Something that will never happen. His vanillin dating test was invented by him as a bogus way to allow for a first century date. It is not only totally invalid, but borders on fraud.
