If they were really concerned about the safety of the children, they’d stop letting us use the schools as polling places. (My community uses city hall and the fire stations.)
I see nothing wrong with using the schools as polling places. I think it teaches the kids good citizenship by example. Have you ever heard of a child being molested, or kidnapped because an election was going on in a school?
As taxpayers, we own the schools and should have free use of them any time we want, as long as it is for legitimate community purposes.
