That's the way, uhhuh, I like it. It's simple commonsense. Don't advertise that you are defenseless. Tear down the stupid NO GUN ZONE signs and erect around the perimeter of the campus "Armed School Employees". Hell, even if the school can't get enough faculty to learn gun training and get a CCW, that would be better that what they have now.
President Trump, as usual, has the solution. I've known this since Columbine. Yes, it will be difficult for some lib/socialists to grasp the idea of some faculty being concealed armed, but why not just put up the sign as mentioned before? Who does it hurt, other than the Snowflakes who say guns are icky.

I believe it to be simple and to the point. If the students don't like it, the Principal can encourage a contest for a different color scheme, as long as they stick to the message.
