Not Disparity Of Force

If my last post was a possible example of disparity of force, this one appears to be the opposite. The article is "Terrifying moment man shoots his neighbor nine times point-blank after heated argument in their front yard turns deadly" from the Daily Mail. The incident occurred in a town in Costa Rica. As the article relates and the embedded video shows, two men--neighbors--got into a heated exchange that escalated to one neighbor throwing some wild punches. The other man--who appears to actually be bigger--steps backward, draws a pistol, and shoots the first man 9 times. In short, what appears to me to be fairly equally matched men where one makes some punches (of little effect) on the other and the second responds with lethal force.
