Quite likely, very objectionable, POSSIBLY unconstitutional legislation would be a better term, as said legislation has not been declared constitutionally wanting by the courts. ATF's tactics, or to be more correct, the BATFE's tactics have been found wanting, if dismissed cases can be taken as an indicator. I believe the same can be said for the old BATF, as it used to be known. Then there was some of the foolishness perpetrated by the ATTU of IRS, however this goes back many years.
In any case, just as their failure to check the egregious tactics of the BATFE is a blot on the face of the Congress, their lack of checking could be descdribed as tantamount to being their stamp of approval for/on the above mentioned tactics, tampering with evidence and harrassment of individuals for instance, it is The Congress that has enacted some really terrible legislation. Of course, the antics of the enforcement agency, ATTU, ATFD, BATF and currently BATFE haven't helped much.
Regarding JPFO, they have an ax to grind, plainly it revolves around the fact that they do not care for the BATFE, as it's currently named. One can readily tell where JPFO is coming from, what their peeves are, things that one can agree or disagree with. With the federal firearms enforcement agency, which as above noted has appeared under various names, one might well wonder as to "where these people are coming from", given their tactics and actions.
As to the NRA, I've been a LIFE MEMBER since 1973, and a yearly and 5 year member before that. Notwithstanding my long term membership in that organization, I still wonder about some of the things they do, as well as other things they didn't do.
