Victor, you're not doing yourself a favor by getting into this so deeply and publicly, believe me. I don't know the sequence of events, I only go by what I read here. You wrote, that you reported stuff you heard to the nacd president... that, to me, sounds a little witch-hunty.
You have also, more than once, implied or said that there are unsafe/bad instructors, but how would you know that? These are serious accusations and they should not be publicly discussed/judged by people that have no first hand knowledge of these events. If you have seen something, then make a 'real' specific report of what you have actually seen, leave out the stuff you heard and have the people come forward that have told you these stories.
I believe that you have good intentions and want to help improve things, but all this posting is not the way to do it, it helps to form little groups. Think about how it comes across to people that read this.
