Article VI Clause 2 of the Constitution reads: ....
The Supremacy Clause has nothing to do with this. Prime said:
it declares that federal law takes precedence over all forms of state law.
That is not quite correct. The Supremacy clause only means that valid federal law takes precedence over inconsistent state law. Is there some federal law that you think is inconsistent with the state laws that GLT pointed out? I'm not aware of any federal reporting law. In any event, your initial statement about the WTS requiring more than the federal government is just silly. Of course the " administrative position of Jehovah's Witnesses" has "the right to require more from the elders than the federal government." They require that elders (and other Jehovah's Witnesses) not own handguns, don't they? Doesn't that go beyond what the constitution allows, in that a state or city could never ban its residents from owning handguns? They can require whatever they want from the elders. They like to boast about being the most morally pure people out there. So why not set the example in prioritizing the prevention of abuse over bad publicity against the organization? Whatever the government requires is a floor, not a ceiling. If you want to boast about your morals, don't do the minimum.
