This sucks. This is leaning further into the Major Questions Doctrine that SCOTUS has been pushing, where agencies and their actually knowledgeable, employed scientists and technical experts, have no real control over regulatory policies, and instead are beholden to Congress and judges to decide e.g. how many ppm of a chemical is safe for people to drink.
Okay, it was everyone who owned a gun and a shoestring. Sure, gun owners are no longer allowed to lace up their shoes. Heres a link to the letter. Thats a sensible rule. https://old.reddit.com/r/progun/comments/p46y9n/just_a_reminder_that_in_2007_the_atf_classified/
So no, gun owners with shoes are not felons, unless they combine those 2 things to make a machinegun. Obviously.
