The common thread through all The Best Defense, is AWARENESS, don't fight if you don't have to, I'm sure the next common thread will be, if you have to, fight like your life depends on it because it does. There is no room for what LE calls around here, fat, dumb and happy, like well fed SHEEP!!
Like I have advised people in my field, 2 wheel drive and common sense will get you farther than 4 wheel drive and testosterone.
