I've seen ATF waffle and duck so many times. I've seen them post something on their web site as an absolute no-no... then it disappears, and next thing I know they've been issuing letters saying the same thing is O.K.. subject to some weasel-wording. But for all I know, day after tomorrow it will be a no-no again.

... and worse.

So far as I can tell they have little integrity and no sense of shame at the lack.
