Well, we know that doors at the Capitol were opened on January 6 to let protestors in to advance an anti-Trump agenda. Is it possible that a school door was opened on May 24 to let a shooter in to advance an anti-2nd Amendment agenda?

I cannot imagine that any order like that would not be countermanded before it got down to the school, or obeyed when it got there.
