This got me interested enough to go back and look at a few of those links.
Apparently, a few years back, someone advanced further (reasonably
significant) evidence for the argument that the location all three samples
were taken from (one corner of the shroud) was actually a "patch" that was
added to fix the effects of wear accumulated over the years. Which means,
arguably, that the samples were accurately carbon-dated yet not
representative of the rest of the cloth.
A few years back, someone apparently came up with a way to carbon-date
entire objects without damage to them (by placing them in a specific gas for
a while, then dating the gas). That could theoretically be used to
carbon-date the entire shroud without damaging it, but it's not like the
folks in control of the shroud are going to believe that easily...
