Along the lines of what TB posted, most people act like herd animals of prey. Avoidance and flight, hell take the hindmost. (read weak, old, children, women, lame, sick, not necessarily in that order) In other words, I don't have to outrun the bear, I just have to outrun you!
A couple of people working in concert could have prevented the senseless death of that man. By pulling him out of the path of the train, or, by nullifying the threat posed by the deranged individual.
In some ways, the mass of sheeple that will die in the 'civil' unrest that will take place, may not be a horrible thing.
The death of one man is a tragedy. The death of thousands, is a statistic. Paraphrase of Joseph Stalin.
