There is no way of preemptively knowing how you will react in a traumatic situation. Most people hope they would be heroes, but truthfully very few would. One would hope at least a couple on lookers out of the many who witnessed this would have tried to do something, but alas only two women stepped forward to shield the man's dead body. I think it's fair to say, in a horrific situation, that people would be more willing to fire a shot at a criminal from a distance, rather than run up and swing a club within a much closer proximity.
