As an attorney that has actively defended many self-defense shooting cases I am very skeptical of a lot of these plans. Recently at my range there was a table set up promoting and selling a plan (I forget which one) and I asked how many claims they've had, what their record was, who the attorney would be to represent me, and how experts are chosen and if there's a cap on expert fees. They could not answer any of those questions. My impression was that they're happy riding out the gravy train until a claim comes in and then they'll figure it out.
There are very few decisions a person can make in their life that are more important than who to use to represent you when charged with a serious crime. Indeed, if you were diagnosed with cancer you'd likely seek several opinions from different doctors covered by your health insurance plan and you'd proceed with the best, most experienced doctor you feel comfortable with. Medicine is more of a science than an art, and yet you;re given many choices under most health insurance plans. However, I believe many of these prepaid legal plans limit your choice of lawyer and expert in a profession that's far more art than science.
Most experts in this field suck. My firm hired the local go-to ballistics and firearms expert many years ago on a case involving a pistol grip shotgun. The buffoon knocked out a tooth pattern testing the gun when he placed it up to his mouth. Since then we've used an expert out of Indiana several times who was nothing less than a miracle for our clients. We got a drug dealer acquitted who killed another dealer during an attempted robbery that happened during a drug deal. We also got a minor house arrest sentence for a home owner who fired several shots from behind into his car as it was stolen and being driven away (the young thug was left a vegetable when one pellet entered his brain). All of this was based on dragging the case out and delaying so that the prosecution got tired of dealing with our motions, depositions, and expert reports. I'm confident that without the amazing expert we used in those cases we would not have secured the amazing results we did.
Insurance companies don't necessarily have the same relationship with their customers as I do with my clients and if I didn't have the freedom to retain experts out of state I'd be stuck with the local zeros. If I couldn't drag the case out until I got a deal I wanted the client also would have suffered.
I represented a litigation funding company for some time that funded complex business litigation suits. Prepaid legal plans operate on a similar financial model. I can tell you that my client was not interested in retaining experts or letting lawyers take any longer than necessary in resolving a case to a minimum acceptable outcome.
Also, I think there's a lot of bullshit misconceptions about why you might even need prepaid legal insurance for self-defense shootings. I'm a firm believer that there are good shoots and bad shoots. This is obviously not completely binary, especially depending where you live. If you shoot someone in your home and you're justified you don't need a lawyer. Hell, the cops will want to take selfies with you and buy you a beer. If you get in a good shot with an armed individual who means you harm then you may need a lawyer while the matter is investigated but it likely won't be a huge fee and it should resolve quickly. If you get in a bad shoot you need a damn good lawyer and a lot of money or else you're fucked. I doubt prepaid insurance would even cover a bad shoot because they may argue it was not a valid act of self-defense.
I've represented clients on appeal in two bad shoots. They had questionable to horrible trial lawyers and neither had funds for an expert. Both were convicted, hence the need to hire me on appeal.
