Baltimore’s worst-ever per capita homicide rate, the 56 killed per 100,000 people recorded last year, made it the most violent city in America, according to new FBI statistics. Given how many people are trying every day to make this city a safer place, that’s dispiriting. But the situation in Baltimore is actually worse than that. Just six years before, Baltimore recorded its lowest number of homicides in a generation — 197. If we had achieved that level again last year, Baltimore would still have been the second deadliest city in the country, behind Detroit but ahead of cities including Chicago, where the recent violence has shocked the nation.
