Horace Mann prophecy watch

Horace Mann, generally regarded as the father of America’s current public school system, once prophesied: "Let the Common School ... be worked with the efficiency of which it is susceptible, and nine tenths of the crimes in the penal code would become obsolete; the long catalogue of human ills would be abridged."

Or not. The Associated Press reports that a tiny Texas school district near the Oklahoma border "may be the first in the nation to allow teachers and staff to pack guns for protection when classes begin later this month." And why not? If teachers and other school employees could be in danger (as this sign from Edmond Memorial High School would seem to indicate), why should they be sitting ducks?
