SECOND
Though I'm not sure I can second my own concept...someone check, I can't remember

This is a long standing rule in my line of work. I distinctly remember an instructor waaaaaaaaaaaay back when I was a basic cadet (1993) telling us about "certifications" and their shortcomings--in other words, having to be certified on certain "defense tactics" such as the carotid artery hold (chokehold), Pressure point controls, etc. etc...
He went on to tell us that if we were in a fight for our lives and the only thing we could get our hands on was a brick, guess what we just became "certified" in? Brick defense tactics---such as bashing the bad guy with the brick until he lets go

I haven't forgotten that one....
In a gun fight, you always cheat--if you plan to win
