Urban "children" of age 19 and younger become victims of violent crime irrespective of the instrument used. Rural "children" are more likely to commit suicide irrespective of the instrument used.
18- and 19-year-old "children" (who are of course legally adults) account for more than half of firearm-perpetrated homicides and all homicides of people under age 20. The same is true for firearm-perpetrated suicides, no matter how you cherry-pick the numbers and spin the interpretation. Calling this an issue of deaths of "children" is an appeal to emotion, and the analysis by the researchers at Northwestern ignores the real root causes of violent crime and suicide.
