The guns would be registered (presumably, like machine guns, subject to periodic inspections by the Bureau of Alcohol, Tobacco, Firearms and Explosives); owners would be subject to invasive background checks, presumably fingerprinting, etc. She did not mention the $200 tax stamp for every transfer (and would that also apply to magazines--each magazine?), but if they are to be regulated "like machine guns," that would be part of it. And ownership of the gun would apparently be contingent on a local judge or chief law enforcement officer approving that ownership--with the official in question not required to provide that approval, or even a reason for disapproval.

Failure to meet any of these requirements would be grounds for confiscation.
