Patriot86, note the recent furor (pre F&F) about ATF attempting to require FFL reporting of multiple long gun sales. Since that happened, F&F broke; Congress specifically denied funding to ATF to enforce that directive. Last I heard, there was still an effort to enforce this in the four states bordering Mexico.
Then, ATF was going to try a new ban on shotgun importations, with a "sporting purposes" review last year.
On a non-gun note, an Executive Order has re-prioritized immigration enforcement so that a wide swath of illegal aliens will not be deported, for now.
EO's can have a big impact, sometimes permanently, but sometimes only until Congress or SCOTUS take countermeasures.
