The only thing ruling it out is a sanity check.

There is no way that Germany and points west in Europe would differ
so vastly in R1b. It just won't happen. Either one lab did not test
the appropriate marker at all and it was not reported in the paper,
or they screwed up the test conditions. If they screwed up, it
is faintly possible that Butler did too, but he or at least his
lab is supposed to be awfully experienced in this stuff.
