Thats a pretty trite response.
ATF, like any government agency, works for US. If enough of is don't like it, well.......change the law. Its really that simple. No enabling law= no ATF to enforce such law. Just be aware that it isn't likely to happen because not everyone views the Second Amendment as do the members of this forum.
It shows the importance of lobbying and electing bonafide Second Amendment advocates to legislative and executive offices. We fail terribly in that respect. We elect representatives who talk a good game, pandering to their constituents yet when needed aren't the 2A person they promised to be. I'm looking at you Donald Trump and Dan Crenshaw.
