Which law is that one? One of thousands of federal laws? One of the thousands of federal regulations? State law? County ordinance? City ordinance?
How is it that any of these edicts can trump the Bill of Rights, and how is it than any man or woman can be expected to know ALL of the edicts, and why is this even considered a "free country" anymore?
Most, if not all, states have laws forbidding anyone other than law enforcement to carry a gun onto school property. I've heard of provisions that allow teachers to carry guns, but I don't know if any of those have ever been inacted.
The article says they were going to town court, I presume that to mean it was either a state law or a city ordinance.

Kids know they can't carry guns onto school property. Most adults do, too. In fact, I have a toting license, and I know all the places that I am and am not allowed to carry the gun. One of the places I am not allowed to carry the gun is onto government owned property (except for state and federal lands where I can hunt). Because I carry a gun, I've made it my business to know the laws regarding carrying that gun. I'm not saying I don't from time to time violate those laws, either because I'm not thinking about it or purposefully because I think there is a reasonable expectation that I may need to use my gun. But at the very least I know when I am in violation of the laws.
Handy piece of information to have.
If you don't like the law, lobby to get it changed. But until you are successful, the law is the law. You can live within the law or you can be prepared to face the consequences if you don't.
