Well...all the different answers will probably make your decision harder, not easier, but...
I'm a member of what you are referring to as Citizens' Legal Defense Network, actually the Armed Citizens' Legal Defense Network.
I like them because they DON'T assign, or send, an attorney when you need one. They suggest that, ahead of time, you find an attorney close to you that YOU have interviewed (that's what it is...a job interview...the attorney is applying for the position of defending you) and that you are comfortable with. They give you info on HOW to find an attorney that is competent in dealing with a self-defense shooting AND that you are comfortable with and could work with in your defense.
As a last resort, IF you have not bothered to do as they suggest, they will get you an attorney.
I like the list of expert witnesses they have that can be called on to assist in your defense, if necessary... Mas Ayoob, for example. Some like him, some can't stand him...but when it comes down to keeping you out of jail its credibility and believability that count, not whether you like him or not, and he is considered to be THE preeminent expert in the field of self defense shootings, whether you agree with him or not.They have quite the lineup of experts beside him in ALL areas of a shooting...victim psychology, pathological forensics, ballistics, stress physiology...you name the needed discipline, they have a good expert in the field available to you.
No...they don't have X dollars coverage that you buy, but they are financially viable to cover your legal costs unless they wind up involved in SEVERAL full-blown trials all at once, an unlikely scenario.
I believe in the ACLDN enough that they are the program that my wife and I choose to keep us out of jail if either of us is ever unfortunate enough to be involved in a legal shooting.
