black students are already given disproportionately heavy punishments, both in the criminal justice system and in schools. will be worse when you involve guns.
The teachers are intended to stop active shooters with their firearms. Do you think teachers are going start shooting black kids for lesser offenses than that? Do you think if a black kid got into a fist fight with another student that the teacher would open fire on them, whereas a white kid would need to start shooting people before the teacher would use their firearm?
cops who have training shoot unarmed black men, so why not teachers who don't sign up for that kind of work?
