There's a fine line between saying "We should change the law to allow X." and "Here's some ways to do X, which just so happens to be illegal."
APS does not advocate breaking the law.
Saying "CCW carriers and Teachers should be allowed to carry in schools because L, M, N, O and P." Good to go.
Saying "Here's how to hide the firearm you illegally brought into the school; Q, R, and S." No go.
