Gun violence is the leading cause of death between 1 and 19 years of age. Want to know why this study chose such an odd and very specific age range? Cut it off at 18 and it wouldn't work, since it would exclude gang violence. Start it at birth and it also wouldn't work, since the statistic would include infant mortality. The "kids" being killed by guns are disadvantaged black youth in crime-ridden cities (Open the supplement - https://www.nejm.org/doi/suppl/10.1056/NEJMc2201761/suppl_fi...). Unfortunately, that doesn't sell gun control, so the study is custom tailored to be manipulative in the way it frames the issue.
