C'mon guys, hey was being facetious. One by (to) the head, warning as he falls, another shot in the area of his feet (he fell backwards).
I seen the humor in it.
I gave a dog a warning shot once, in the grass infront of him as he charged. It worked great and turned him right around. But dogs you can reason with unlike most humans...
I'm not positive that I agree with the doctrine of if you draw you shoot. What if they see your drawing motion and cease hostilities? Happened to me once, drew to low ready and it was over with no shots fired. You may not have time to see him cease being hostile in his body language, and in that case I guess he gets shot. But I had time to see and am very glad I didn't have to shoot. Critique this as you will.
