it had a single year during covid when everyone was closed in

Not getting too involved but just a heads up for everyone, that study was highly flawed. It considered 18 and 19 y/o as “children” and only took place in a few cities which coincidentally happen to be some of the worst cities for gang activity in the country (which targets kids for members, often recruiting at age 10-13), NYC, LA, CHI, Philly, and iirc BMore. It also did indeed take place during covid lockdowns when less kids would have been involved in traffic accidents (the actual biggest killer) due to zoomschooling.

Sure school shootings are a problem, but that particular study is bad.
