Wow, what a gruesome way to go. What always amazes me in situations like these (video of the Boston Marathon bombings is an excellent case study) is the widely varied reactions by the people in the immediate vicinity of the incident. To me it says a lot about the innate unfiltered character traits of the human species. In general, it seems people tend to: 1) run away immediately to safety 2) run towards and take immediate action 3) too frozen in fear to move at all 4) move randomly, knowing something should be done but not knowing what that is 5) ignore and not acknowledge what they are seeing, as if that will make it not real Same goes for combat situations it seems. Sometimes training takes over to move the body in conditioned responses, but sometimes not. Very interesting to me for some reason.
