Pretty much, if you want to get away with killing somebody, as talk is cheap and always has been. I have always used the hands on rule. I had two guys after me in AIT, I never took the bait, just on words. I waited until told they had seen me enter the building and were going to "throw that little white redneck cracker down the stairs", so I insisted on going up by myself (to avoid a race riot), knowing I would kill the first one, and deal with the other, but expecting him to retreat. So, the first to grasp and swing, got thrown down two flights of stairs, bouncing off a concrete wall, but with less than expected result, only getting compound fracture, forearm and wrist, with severe bleeding, and a huge bleed dent on the right side of his head and a concussion that kept him in the base hospital 3 or 4 days, but even then I treated his injuries, immobilizing the fracture, packing the bleed with his t-shirt and tourniquet above the elbow and calling the ambulance. The other guy retreated. I don't make the first move unless outnumbered beyond abilities, as thin it becomes a matter of getting your payback in first while you are still able. If somebody dies, it's the fault of the one that initiates action, in my book.
