That depressing stat comes from my colleague Jonathan Lai, who wrote earlier this month about the epidemic of kids being shot in the city. Among the things Lai uncovered was the fact that kids made up a larger share of shooting victims in Philadelphia in 2018 and 2019 than in previous years. That includes shootings like Nikolette Rivera, a 2-year-old who was in her mother’s arms when she was killed by a stray bullet in her own home.
