This isn't how "they" push the lie about guns being the leading cause of death for "children" though. They just say "children" and include 1-19 year-olds while excluding kids <1. I think we all understand that when they say children that it shouldn't include 18 and 19 year-olds.for the sake of this discussion, students could be those enrolled in an educational environment at the time of the shooting, perhaps?
I mean if you don't want to lump anyone over 18 in the statistics because they are legally 'adults' then how would you propose separating those involved in a school shooting who are 18 vs those who are under it?
"Student" would seem a pretty good way to do it, but if you want to continue to debate the meaning of the word then i guess i'll defer to you on how to identify the group in question so that we may better understand that group is it relates to the overall statistics.
