However, the federal government takes a completely different position and believes that it has the authority to legislate and regulate firearms anywhere within the borders of the United States.
In the last few months, a grass-roots, federalist revolt against Washington, D.C. has begun to spread through states that are home to politically active gun owners. Montana and Tennessee have enacted state laws saying that federal rules do not apply to firearms manufactured entirely within the state, and similar bills are pending in Texas, Alaska, Minnesota, and South Carolina.
Yet the Bureau of Alcohol, Tobacco, and Firearms, and Explosives now claims that that not only is such a state law invalid, but "because the act conflicts with federal firearms laws and regulations, federal law supersedes the act."
Below are two (2) July 16, 2009 letters from the Bureau of Alcohol, Tobacco, Firearms & Explosives to Montana and Tennessee respectively notifying the federal firearms licensees in these States that federal law supersedes the Tennessee Firearms Freedom Act, passed on June 19, 2009 and the Montana Firearms Freedom Act, effectively on October 1, 2009.
