There was a time (because of my White heritage of belief in proportionate response and fair play) that I believed that just knocking them down and out was enough. Not anymore. Remember, these little shit-stains would gleefully see you dead. So now, as long as the situation remains just hands? Sunshine isn't leaving the scene without some sort of life-altering structural damage that: 1) absolutely requires a trip to the ER, and, 2) permanently reduces their capacity for any future bullshit. Not lethal force. Just a high percentage chance of being permanently debilitating. A good hard stomp, shattering either patella, or the wrist/elbow of the dominant hand should slow them down a bit. Of course, the instant he comes with anything at all in his hands, and hey, suddenly, all bets are off, and "I feared for my life.", becomes the mantra.
