OK, Jerry, we are edging closer to what seems to be the only legitimate
answer right now, namely, that there is no unassailable evidence that a
distinct and definable population of Northwestern Crow exists (or, for that
matter, ever has existed) anywhere in Washington. Bill does claim that
"Johnson's 1961 paper... can easily be shown to be methodologically
flawed," so I doubt that he would base any claims on it, one way or the
other. Returning to Bill's courtroom analogy, I think that it is
appropriate to remember that OJ got off at the "beyond a reasonable doubt"
standard in the criminal trial, but they nailed him in the civil trial on
the lesser standard of "a preponderance of the evidence."
