Sign of Our Times: The New Normal?

This is a sign from Union Grove, Texas where licensed and trained teachers and administrators now carry a firearm. Is this sign supposed to convince killers to move down the road to the less defended school?

As we recently saw, other schools are conducting unannounced practice raids by hooded police pretending to be homicidal killers.

The question is how is this new environment going to affect how our children view the world and their government. What impact do such signs have on children in accepting a greater role for authority and police presence?
