No, we are not. My instinct during a stabbing attack I witnessed was to run towards the danger. But I'm not sure what that has to do with the fire drills you mention, those are a vestigial leftover from wars-of-attrition scenarios. In my opinion not freezing up (or unfreezing faster) is a matter of experience and can't be replicated with country wide training. Sounds about as useful as duck-and-cover videos from the cold war era. Also, living this way is not desirable in and of itself and "your societies" are not in proximity to war zones. Just control your firearms.
