told my husband that all doors leading into schools should be locked, and remain so--of course they're made that you can open them and get out, but no way access should be so easy. buildings full of potential victims, and anyone can just walk in. think about it, when was the last time you walked into your kids school and anyone challenged you or asked why you were there?

only one entrance, with an intercom and camera system--buzz the button, state your business, and then they let you in--maybe!

i think it wouldn't hurt to have all class doors locked as well.
