Well thank goodness the bomb turned out to be a dud.  So... in that case, no one is the hero?  Because there was never a threat?  I end these in question marks because, I wonder myself.  But I think everybody involved who stopped this mess from happening deserves the title hero.  The pedestrian and the cop, because without the information from the pedestrian and the cop taking action, then the threat could've turned out to be something worse.
