From the article: > This summer, I published a book called Bleeding Out that explains how we could reduce gun violence by 50% in the US’s forty most violent cities. The plan would take eight years and could save more than 12,000 lives. It would cost about $100m a year. > Many people find it hard to believe that we can do a lot with a little on this issue. But urban violence is actually a more solvable problem than most of us realize. > In the cities that struggle with high rates of violence, shootings are concentrated among a surprisingly small set of people and places. It doesn’t concentrate in entire communities or neighborhoods. Even in the most allegedly dangerous places, the vast majority of people are not violent, and there are plenty of safe spaces. > In fact, in most cities, about 4% of city blocks account for approximately 50% of crime. In Oakland, 60% of murders happen within a social network of approximately one to two thousand high-risk individuals – about 0.3% of the city’s population. In New Orleans, a network of six hundred to seven hundred people, less than 1% of the city’s population, account for more than 50 percent of its lethal encounters.
