At the U. of Minn, Behe was asked about bacterium Yersinia, with a Type III secretion system and flagellum; Behe stated that the bacterial flagellum is still irreducibly complex in the sense that the subset (TTSS) does not function as a flagellum.
Huh? If there is a functional subset (I don't think he's claiming that Type III secretion systems don't exist) then it's "reducible".
Behe is a professional misspeaker.
