ATF ignores appropriations report language
Red's Trading Post has the story.
Basically, appropriations and other report language doesn't bind an agency, it isn't law. It's generally a good idea to comply (which is why report language is now being used to hide earmarks) because if an agency doesn't, the appropriations committee may cut its budget next year. In this case, I'd guess that ATF has no fear of that, so it just keeps going.
