You never know what's going to happen where. There may be police close by and there may not be. The more folks that have a gun and some level of shooting ability, the better the odds are that they are in the right place at the right time to help. LEO can't be everywhere at once. Still, as was mentioned, the chances are far greater that LEO is going to respond in numbers a lot faster than you are going to be able to get together even a 3-4 man team. Sure, it's possible. If you live in Fayetteville or Jacksonville or Havelock and are military and you live somewhere with 3-4 of your buddies right there in the neighborhood, then the chances are pretty good that you could respond quickly to an event close to you. But for most of us, that's not the case. We would be lucky to even have 3-4 CSC'ers within a 3-4 mile radius. Much less 3-4 with similar skills/abilities/interests that would want to get together and train. As was said, I think it needs to be more about individuals that have some level of capability with shooting. But I also think there needs to be some way for LEO to recognize those folks as the good guys if LEO shows up on scene after that individual has engaged a bad guy.
If something bad happens and a policeman shows up, most people assume he knows something about what he is doing and that he can shoot. CSC members that meet standards could (over time) get that same recognition. I would focus this more on setting a standard and then having LEO and the public recognize that you are someone that has met that standard. That would be much easier (and I think, more effective) than trying to organize a militia.
Setting standards and getting them recognized I think would be a good first step. There needs to be recognition within LEO and the public that what a CSC certification means is that you have met a standard and know your way around shooting/guns. Don't make it too tough or too expensive to get, or you won't encourage people to get it. But it does need to be a higher standard than what a typical police officer has to meet, as to shooting ability. Then that recognition means more. You can't simply take everyone that wants to join, or you'll just get more of the badge and reflector belt comments. OTOH, ever single member here has something they can contribute to a militia situation. So doing both is a good idea.
Regardless of a militia or CSC, if I were running a training company, I would set up a certification level (or levels). I've never understood why they don't do this. Some may and I just don't know it, but none that seem to be generally recognized. Most people like to get certified. It may require taking a couple of courses, along with meeting standards of shooting ability. Good for the instructor and his company, good for the person getting the training, and a generally recognized certification would be a big motivator for all of us to get more training.
Only way I'd join a militia is if McCrory authorized it. So the work would have to begin on the political front. I would say that with all of the threats of terrorism, this may be a very good time to try to get an approval. I wonder if anyone has ever asked him? Even though I think individual certification would be much easier and more effective, I do think if you could get that official approval, that it would take off. It would be interesting to attend meetings and trainings and gain more knowledge. If it becomes too anti-government or political though, I'd be out. Keep it's mission simple... to help people in emergency situations.
