>I suspect the trigger was the realization recent especially egregious cases were being prepared for court cases, which were likely to be won.

I should've thought of this. Can you reference a specific case? I'd like to follow it.

>Agencies like this would rather voluntarily pull back to prevent a court ruling setting precedent. The agency can always bring back similar measures in different forms or with different supposed safeguards but a court ruling is beyond their control.

I need to review the federal jurisprudence on this. IIRC there were some finer points that changed so "don't worry we changed the rule" is no longer as good a defense as it once was and that's part of what led to Bruen making it into court in the first place.
