Im not too thrilled with getting the NRA mafia involved either but it might end up being a necessary evil to standardize a course standard in the beginning but once thats done I would open it up to any competent instructor.
It's not surprising that you are not informed on the many training programs that the NRA not only conduct but initiated. In part, that is one of their downfalls. Most folks only see, that they just oppose gun control and are strictly a lobying group/mafia. Most of what gun folks see is mailings, asking for donations. On many fronts, they have set and protected the foudation for everyone's rights. They need to better communicate their good deeds and not just pop up when the rats at the door. ....
Be Safe !!!
