George Orwell is credited with saying that we sleep safely at night because rough men stand ready to do violence to those who would harm us. Last night an assortment of law enforcement officers from various agencies played out Orwell’s aphorism while television cameras rolled. The cameraman was too far away and it was too dark for viewers to do much more than hear the gunfire, but from the sounds of it, the firefight was intense. As with the immediate aftermath of any such an incident, details are sketchy, confused, and somewhat conflicting. What is not in doubt, however, is the heroism of those officers who put their lives on the line to protect the citizens of Boston. I salute them, and all law enforcement officers everywhere who daily stand ready to do violence to those who would harm us.
