Is this an opening against "May Issue" CCW?

Via Dave Hardy, news that a U.S. District Court judge is requiring that an Iowa sheriff take a basic course on the U.S. Constitution after denying a local activist a CCW permit because his views are unpopular.

This is a paradigm case, one in which the issues are very clear. But the problems Paul Dorr encountered are those of nearly everyone who is denied a CCW permit in a "may issue" state: a sheriff gets to decide, arbitrarily, based on extra-legal factors, whether you, too, can join the privileged few and discreetly carry a firearm. One can hope that legislators and judges in New York and California have taken note of the Dorr case.
