vranasaurus, if this is like the Armed Citizens' Legal Defense Network
http://armedcitizensnetwork.org/ (alluded to by jgcoastie, run by Marty Hayes, and including Mas Ayoob amongst its expert defense witnesses), it means that they will start by assigning an investigator to look at the basic facts of the case. If it appears to be a good shooting by the association's standards, they will then assign a legal defense team.
Just because a case has been charged, does not mean it is prima facie a bad shooting. That could mean the DA thinks it might be; or it could mean the DA is the type who views any shooting as a bad shooting; or it could really be a bad shooting.
It does mean that if a shooting appears on its face to be bad to the association's investigative team, then one is not going to be assisted. Hopefully, nobody on TFL will be so poorly informed about justification as to involve himself in an obviously bad shooting.
Also to vranasaurus, here's a current thread about a case where a DA charged the shooter, even though the case seemed to be self-defense, and was ultimately determined to be self-defense:
