The term hero gets thrown around pretty flippantly in my opinion. For one thing victim of a tragedy is NOT synonymous with hero. This may offend some folks but when has that ever stopped me before? For example an office worker who died in the WTC trying to get out is a victim, the Police and Firemen who ran into that same building putting their own lives on the line to save others, those are clearly hero's or at least attempted hero's. Being a hero means putting your own safety aside in order to help someone else. Not every soldier is a hero, thats why they have medals for the exceptional ones. Like I said some people might take offense to this idea that just being in a certain uniform doesn't automatically make you a hero, to me it is offensive to the real heroes when people who haven't earned it are referred to as heroes.
Why do I bring this up? Because here are some real heros they saw a tragedy unfolding and they ran to see what they could do to help rather than running away.
