There were a lot of true heroes in yesterday’s attack on the Boston marathon—police, paramedics, doctors, runners and spectators who rushed to help rather than run for their safety. One of them is Carlos Arredondo, who helped apply tourniquets to a man with severe leg injuries from the blast and deliver him to an ambulance.

These people saved lives yesterday. In the midst of unthinkable horror, they did what they could. Absolutely amazing.
