The tax payers are paying for them anyway, I have no problem with them frequenting school grounds. In fact, patrolling school parking lots would be a fine way of seeing who is coming and going. I know of no shooting at the school and hope to keep it that way.
I have also spoken to several retired corrections officers who said they’d be glad to spend a few hours a week at a school in the interest of security. Not sure if they would even have to be paid at all.
