I can't speak to ACLDN, but if you're looking for an alternative, give US Law Shield a look.
https://www.uslawshield.com/I've been a member for a few years, luckily haven't had need of their services, but I have a friend who has.
It's still in the courts several years after the incident so he hasn't told me all the details of the incident, but US Law Shield has been covering him since day one, and all these years later they're still fighting for him in court, both on the case itself, and also making sure he still has possession of his firearms and NFA items as well.
(Oh, and remember the church shooting in Texas a few months ago, and the hero Jack Wilson that head shot'ed the perp from across the room? He's a member too... )
(Other than being a paying member, I have no other connection to them and get absolutely nothing if you or anyone else choose to join.)
