> So what else are you suppose to do? I think it's reasonable to decide that if no one is enforcing the new local law, that it may be the commissioners purview and authority to enforce after exhausting all his options.

County commissioners are generally legislative officers. While the legislative body is smaller, this really no different than a member of Congress deciding that the they don’t like the way DOJ is enforcing federal law and deciding that gives them arbitrary power to take whatever action they feel is appropriate to manifest the intent of the law.
