Wyoming you say? Hmmmm....

Yes, I believe this is going to be a trend. States will begin to assert that the Constitution as regards to regulation of firearms can only apply to guns not manufactured and remaining in that State.

Still other States, I believe will follow and form a pact to defend any Federal violation of States' rights of a sister State. The Fed will then be forced to think about whether it wants to touch off a Civil War over the issue.
