When it was pointed out on TO that bacteria far outnumber all other 
lifeforms on the planet I once joked that the designer had obviously 
created multicellular lifeforms as condominiums for his prize pet 
bacteria, and that when the designer got around to checking back in that 
there would be hell to pay when he finds out that one of the 
condominiums is using things like antibiotics and soap to kill trillions 
of his pets.  Behe may think along the same lines because why else would 
a designer give a plague bacteria like Y. pestis a flagellum?
