From the link above:
"First, it must be noted that what was issued yesterday was not, in fact, an
“executive order” by the President, but merely an “executive
guidance” by the Bureau of Alcohol, Tobacco, Firearms & Explosives (BATFE).
The portion of the policy change related to the “gun show loophole” states
explicitly on its second page: “The guidance set forth herein has no regulatory
effect … ” Further, at least part of that guidance (the portion addressing
changes to rules for NFA items, such as machine guns) will not even take
effect until 180 days after publication in the Federal Register, and it’s not
clear that step has even been taken as yet.
The die is already cast in its effect to chill the free exchange of privately-owned weapons between individuals -- something most definitely outside federal purview until this time. Yes it will be challenged in court. Yes it might be rescinded if a "Republican" is elected. But it's portent of change as to Big Brother's reach down to the very core of just one exchange of one weapon by one individual -- by the Attorney General herself no less -- cannot be ignored.
Moreover it has lent its banner to whipping the disarmament mob in the streets into a frenzy -- for now they have the very realistic bureaucratic language, the very specific target, the concrete goal, the sine qua non of national control at the very lowest level... to rally around.
Never underestimate the power of that combination, especially with the only check against it -- the Congress -- demonstrably powerless to stop a man who will simply veto/ignore any legislation against it.
