He is a hero just like anyone else in the Boston PD that responded and helped people after the attack.
He happened to be posted there at the time. If he did something above and beyond the call, then yeah, maybe. But to call him a hero because he happened to be there at that time, did what he was paid to do, has his picture on the front of SI and is a sexual deviant...well, let’s just say that I have a different definition of a hero.
You don’t know what a hero is.
