Dear gun grabbers,
Good luck putting that cat back in the bag. You’ll need more than luck. But what decent government would worry about ordinary citizens being armed? [Ha ha!]
sincerely,

They don't care about putting this particular cat back in the bag. They want to ensure that this guy does not continue his development efforts, and discourage others from developing and disseminating directions for how to make fully-functional easy-to-make firearms on the internet.
Look for the next step to be indictments under ITAR for others who put manufacturing instructions on the net for things like AR lower receivers. Also, they will try to regulate 3D printers. Perhaps they will try to force makers to require any design to be uploaded to a central site, where it will be digitally signed and stored, thus removing people's ability to anonymously make things that the govt disapproves of.
