If ever there was a sign that exemplified the era in which we live, it well might be this one, a picture of which I snapped at Lovelady High School in Princeton, Texas.

I am 73 years of age and the message on this sign — about armed security personnel using “whatever force necessary” to protect teachers, students and staff at Princeton Independent School District — is one I never envisioned seeing when I was coming of age.

Or, for that matter, when my sons were coming of age in Beaumont, Texas.

The spasm of gun violence in schools has prompted Princeton ISD to hire armed guards at all its campuses. The security personnel all are firearms-trained; some are retired police officers. Farmersville ISD, just seven miles east of Princeton, has a full-time police force with Texas-certified police officers on duty on its campuses.

This is what we have come to in this country. We must warn visitors to our schools that armed guards are on duty and will do whatever it takes to protect human life against loons with guns.

Amazing … simply amazing.

You want a sign of these troubled times? There it is, folks.
