Granted I have never had FoF training, yet. But is it normal procedure for a FoF instructor to be carrying a live loaded pistol while teaching the FoF class?
Personally I find that moronic and retarded.
It depends on the situation. I've never participated in force-on-force training where there wasn't at least one person in the room the room who remained armed for security. The key is, that person never participates in the scenarios. Anyone who participates in the scenarios removes all their gear and gets patted down, including the instructor(s).
