Unless they train frequently I can't imagine this working well. When I was at military we did shooting exercises at targets. This was easy but as soon as there was an exercise where the situation is messy or you are under pressure things fall apart quickly. There were situations where our group would have killed each other instead of the attackers. You need a lot of training to do that right. I don't know how things…
More guns is not the solution to problems with guns.
Improving access to medicine, economic stability and programs that help empower educators and students to build safer spaces may be though.
In my school all the kids knew who was having a hard time and who was isolated, it would be better to reach out to these students rather than shoot at them. Students are going to school to learn and we're teaching and modeling militarism and violence.
The reason, my guess - doesn't make headlines, isn't good for bottom line.
