Almost. There was that guy in the tower on some (Texas?) campus...
Charles Whitman at the University of Texas. I lived in a college town in Pennsylvania, and a new girl in class the next year had a father who had been walking across the campus when Whitman opened fire. He wasn't injured, but the pipe he was smoking was shot out of his mouth.
I stand corrected. That was the UT tower in '66. I intended to mean public schools, like high school and below (where prayer was removed).
