I did not understand where the 100,000 schools came from and then realized you weren't counting private schools! Police are not teachers. Security is not part of the Department of Education.Do the math
100,000 schools share $40,000,000,000.
If the private schools are paying taxes, and their parents are taxpayers, why shouldn't the police protect them as well as everyone else's kids?
Most private schools are not these super wealthy schools for elites. They are catholic schools, charter schools, and other schools that service the average American.
