The letter is a nice touch and shows support for us.
Holder who likes to play to the press will not be moved. I suspect that if the AGs had told him the law would not take effect, as the federal government has no jurisdiction and would not be enforced, the letter would have been more forceful.
As the Appellate court in Chicago (7th circuit court ) has stated the the Supreme Court rulings (Holder Vs Washington DC) have no force of / in law. Then the opposite must be true that the federal laws have no force of law in the states. Furthermore that the states alone are able to make firearms laws, that are the only laws that are enforceable.
Interesting that the 7th circuit court also says that the Bill of Rights has no affect on the states. That statement is wholly untrue as we all know.
Liberal logic. What an oxymoron.
