From The Truth About Guns:

If you’re an individual who’s suing a federal regulatory agency and that agency then knocks on your door to conduct an audit of your business operations, is it reasonable to conclude that the two events are connected? Would it be fair to suspect the agency of trying to harass the plaintiff who’s been challenging their rulemaking…and winning?

That’s exactly what’s happened to Michael Cargill who owns Central Texas Gun Works in south Austin. Cargill was the plaintiff in the eponymous Cargill v. Garland bump stock case. Cargill won that Fifth Circuit battle resulting in bump stocks currently being legal in the states of Mississippi, Louisiana, and Texas.
