The have had tables at a couple of shows I attend, but I haven't seen them for several years.
Having dealt with the (now) BATFE for about 25 years, I've found the lower level agents to be no better or worse than any other law enforcement agency, and like those other agencies, there will be a few badge heavy jerks that give the rest a bad rap. Most are polite and courteous with the exception of one or two that could have used a few Carnegie courses. The corruption, political nonsense, and blatant anti gun activity appears to be in the upper levels of managment and most street level agents I've had off the record conversations with, don't like the bad stuff any better than we do.
The amnesty rumor may stem from a recent federal court decision that reversed some BATFE decisions on the legality of class III auto sear ownership, that will probably boil over into other BATFE decisions being reversed. Could be turned into a good thing for gun owners but with this administration, don't count on it.
