I saw six people huddled on the sidewalk in front of me; through their legs I saw what looked like a body on the ground. I rushed over to see what was going on. I saw a man with a bloody gash on his head; he appeared to be unconscious. I pushed through and started checking him out using my Boy Scout First-Aid training. His clothes were filthy and tattered, and he smelled bad, but a quick examination showed that his wound was not very deep.
