How about you try taking a determined homeless man down with 3 of your buddies? It ain't all sunshine and rainbows, i'll tell you that. When someone is hopped up on adrenaline, they can do almost super human things. Theres a good example in Minnesota I believe. An officer shot a man 14 times, including in the chest, heart, diaphragm, kidneys, and eventually, 3 times in the head. Before being hit in the head, the man continued firing on the officer until being taken down. Even after he had 3 bullets in his brain, he STILL had vital signs. That is a man who was shot 14 times, let alone a homeless guy who had been shot 0 times. Anyway, the point is, once adrenaline (or other drugs) kick in, you need more than 4 guys.
