Regardless of what you write, there are non-law-enforcement people in the US who can legally walk into school with a gun. I don't know about every state, but in Utah if you have a permit to conceal, you are good to go in a school.

I recommend Legal Heat, a site that spells out the current regulations state by state, about where you can and cannot go while carrying a firearm.
