There are nearly 500,000 school buses in the US.
We have about 1,300,000 people in the military.
We can put one service person on each school bus in the country, or we can wage war, but not both.
If our schools are to be defended, the resources have to come from people already in place in schools, or from volunteers. The original American ideal was no standing army, and little in the way of a professional police force. It was more or less the Swiss model, where everybody goes about their normal business until there is a time of need.
