I, too, had a grim and gruff coach in my Calif. HS in the 60's. He was found shot to death on his front porch. Today, his chances of survival would be even worse. Many kids will want to kill this "sucka." He'd better watch his back.
Well, I cannot speak for what you experienced in California...but in Texas it would be just as likely, perhaps even more so, that those who would plan and try such a thing would find themselves on the receiving end of accurate return and supressing fire themselves.
