No... that is not "it". There is much more evidence invalidating the carbon-14 testing. The sample was taken contrary to the agreed protocols; the area it was cut from was an area that had been rewoven in medieval times (threads on half of the sample are righthand twist while the main body of the shroud is left hand twist); and a large body of information shows that linen is inherently un-carbondatable with numerous samples of Egyptian linens from mummy wrappings dating hundreds or thousands of years YOUNGER than the body they wrap... yet clearly they are contemporary with the body.
The dog ate the carbon-12.
