Self defense includes anything that helps to save your life. No holds barred, IMO. That said, is something like Gymkata considered a valid form of MA? If so, does the arena have to be at a place where there's a pommel horse?
I understand the metrics of a preconceived situation....anybody would. I'm only saying that I've shot most of my range time with face/head shots because I know that it's final.
It should also have a section on fore arm furniture removal. I know that top and bottom fore pieces are a little involved.....I'd also like to see a section on the trigger group, etc.....
