Catching up on some more of Bill Frady's Lock N Load podcasts, and for those interested in "insurance", you might want to download and listen to episode 770, skipping ahead to the 56:10 second mark, where Sean Maloney of Second Call Defense interview starts.

I put insurance in quotes, as he covers the finer points between insurance (by law they can't forward you any money) and a system as Second Call Defense, where they get around some of the legal limitations of insurance.
FWIW, I think Second Call Defense may now be one of his sponsors.
The more I hear from these folks, the better they sound!?
Sean Maloney did pay homage to The Armed Citizens' Legal Defense Network (my baseline), but says Second Call is a much bigger outfit and has access to more money / more coverage. He also goes into how they cover your civil case after any criminal case is settled / closed.
EDIT: I've been going thru Second Call Defense's site (signed up for their newsletter to get the free download) and it looks like they are a combination of The Armed Citizens Legal Defense Network and NRA backed insurance from Lockton Affinity - basically rolling two different types of coverage into one plan.
