One of the issues that New York State used to attack the NRA's Carry Guard insurance program is that it's unlawful to insure against illegal acts. If that's true under the laws of all (or most) states, then no insurance can or will help you if you're convicted of a criminal charge.
But many of the programs out there aren't insurance programs. There are web sites that compare them, so you can see which are insurance compared to which are only (essentially) legal services cooperatives. Here's a link to one such comparison:

IMHO, the ones that say "No" for Civil Damages are not insurance plans, they are just legal defense plans. Frankly, if you go to prison because a shooting is ruled to have been a criminal act rather than a justified act of self defense, a civil claim against you is one of the last things you might worry about. But, as O.J. Simpson learned, you can be acquitted in criminal court yet found liable in civil court. (If you want a proper explanation of why that is, ask -- perhaps Frank or Spats will provide a suitably lawyerly explanation.)
So your worst nightmare is to be in a shooting, be found innocent in criminal court, and face a mega bucks lawsuit in civil court by the person you shot -- or his/her family. That's where having some insurance, on top of having your lawyer bills paid, can make a huge difference.
