You would still have the Feds to deal with.
Ok, I can see that. But if the feds say your operating within state lines........
Let me think about this as marijuana being a FIREARM instead. That's right, a BIG NASTY **GUN** oh no! I'll use two states, Florida and Nevada that are famous for allowing pistol sales without actually requiring any license or anything. You can buy the pistol and own it legally without a permit.
If you own it in Florida, your legal.
If you own it in Nevada, your legal.
If I own it in New York, your illegal because you have to register it there (and then the gun might not even be legal still!).
BUT, if I drive from Florida to Nevada, that's legal since the state I'm going to and from allow the firearm. I have to get it there somehow, right?
So if you use FedEx and ship a pound from CA to CO, I'd see that as legal too.
Am I off base or not thinking it through somewhere? Its nothing I'd want to do, wrong states for me to care about, but I dont think its illegal?
....or nobodys been caught doing that yet and it hasnt been tested in court as legal yet, that could be too.
Who knows!
