What exactly are the rules regarding concealed carry on school grounds or in a school in the state of Missouri(and federally)? If I'm reading it correctly, the Missouri law states that a school is a prohibited place but is not "illegal," although it is covered under a federally restricted location. It seems that the wording in the federal laws allow for carry in schools if permitted by the individual state(in this case MO). Is this correct? It was my understanding that carry in schools was prohibited by the federal laws but the wording seems a bit confusing. Also, what are the differences between a school zone, school grounds, and a school building? Any input would be appreciated. Thank you.
