In my mind it means the citizens should be able to own guns to be able to form a militia incase we have to defend our selves from out gov't. In this case should also be capable of buying weapons with proper licenses that can compete against out military incase our gov't turns them on us. It is to protect us from tyrants period. How can we protect out selves with a bolt action gun? or even a semi auto? Now this is worst case scenarios countries divided as citizens are at war.
My meaning is you touch my damn gun you may leave with it, but after you check out of the hospital and arrest me.
