First thing that comes to mind: It's a given rule of a thumb that in general, the majority of what the media claims is either inaccurate, incomplete, or utter BS. So until we hear the full details, I don't see any reason to assume the worst. I, for one, kinda sorta believe in the whole "innocent until proven guilty" concept-thing that's been floating around for a while.
Second, while I don't fully disagree with the perspective many are taking on this issue, the fact remains that it's damned scary when it becomes a legal necessity to shut up and keep out of sight or risk losing your freedom and possessions. A very large part of the problem the gun community as a whole faces is the fact that we're not visible enough: that far too many people, particularly in urban areas, don't have the hands-on familiarity with firearms that is vital to understanding and supporting the RKBA. No, mall ninja-ism isn't going to help with public perception, but neither will hiding in a back closet and trying to keep from being noticed by the wider world. If his actions are legal, as it seems likely that they are, then the decision to let his hobby be known to the public is, and ought to be, a matter of personal preference.
Finally, does anyone else wonder about the "assistance" of the ATF? One always wonders when they say that if it actually meant one agent with ten deputies, or ten agents with one deputy.
