I find it so amazing that only a few decades ago, children would take firearms to school so they could work on them in shop and if competing in rifle team events, they were often required to take them to school.
I’m 45 years old and I carried my grandfathers old Winchester model 97 trench gun he had to school to show in a war and armaments class I elected to take in 7th grade. I didn’t have a case so I wrapped it in a sheet, handed it to the bus driver then took it in and handed it to the teacher before my fist class started. Brought it home the same way, and this was in Brighton Michigan, not exactly a backwater rural area. If my son did the exact same thing on the same bus route now I’m thinking they would call out a SWAT team to deal with him.
IIRC Chicago’s Mayor Daley just recently ended competitive riflery for Chicago High Schools.
Of course, up to that point no crime was ever committed by those students.
