Did you bother to look?
Not to forget the statements by such experts as Gilbert Raes, Mechthild Flury-Lemberg, Franco Testore and Gabriel Vial.
People who, unlike Jabba and the absent JP, have the skills and experience but actually examined the cloth.
Indeed in the preliminary discussions about where to remove the sample for radiocarbon dating Flury-Lemberg pointed out that STURP's initial choice were more likely to be contaminated.
Well he had linked to a few bits, though when examined they either prove to be nonsense, already debunked, wrong, irrelevant or actually contradictory to his claims.
However I feel I should provide references for the statement I've made about various aspects of the radiocarbon dating, therefore here's my reading list:

It'd also be nice if Jabba (one one of the shroudies) actually did the calculations on how much material would need to be introduced, and of what age, to skew the tests. This would show they have some understanding of the process.
