Thank you for the detailed response - as a layman, I assumed it'd take a warrant or something more significant to justify that many personnel at one place, especially for what's supposedly a routine thing. Thanks for taking the time to explain that and improve my understanding!
As to the FFL revocation issues; are they no longer offering any grace period to straighten things out? I've heard of big box 01FFL's getting as much as 30 days to clean up bound books/hunt down paperwork for a re-inspection.
I know that FFL's known for repeatedly having issues often get suspended/revoked immediately. Obviously, the higher the volume the easier it is to make mistakes, but from other posts it sounds like this place had a pretty solid operation.
I suppose that's the other detail missing - if this were the hail-mary final chance to keep their FFL, and they needed more time to triple-check all their records to ensure 100% compliance, that would explain calling in favors from Congresspeople. But it still doesn't explain that many ATF personnel, at least based on my understanding and experience.
Honestly, it's less disruptive and usually more organized to have fewer personnel, especially since most of what they need to do is usually done in a back office with the paperwork, bound book, vaults, etc. To @
WobblyPossum 's point about Fed LE orgs changing SOP's to just use tons of people on stuff like this - they really need to consider the optics, especially the ATF.
As an 01FFL playing by the rules, the ATF have a very necessary role. But with their higher leadership mucking around with things like the pistol brace mess, the ATF doesn't need to throw any new eggs on their own faces if the same goal can be accomplished effectively and safely with fewer personnel.
