There’s the exception that allows school boards to approve CCW in schools like Texas and other states.
“(g) Exception
Nothing in this section shall apply to a firearm that is lawfully stored inside a locked vehicle on school property, or if it is for activities approved and authorized by the local educational agency and the local educational agency adopts appropriate safeguards to ensure student safety.”
Love it-—the schools should have their own gun safety and target shooting classes.
From my CHL class, I was told that it’s okay to pick up your kid at school while armed, as long as the weapon does not leave your vehicle. I’m pretty sure teachers can be armed if they have a CHL and permission from the school administration.
