Mas Ayoob repeats what he said after Columbine:
If we simply prepared teachers to handle this type of crisis the way we teach them to handle fires and medical emergencies, the death toll would drop dramatically. We don’t hear of mass deaths of children in school fires these days: fire drills have long since been commonplace, led by trained school staff, not to mention sprinkler systems and smoke alarms and strategically placed fire extinguishers that can nip a blaze in the bud while firefighters are en route. In the past, if someone “dropped dead,” people would cry and wring their hands and wail, “When will the ambulance get here?” Today, almost every responsible adult knows CPR; most schools have easily-operated Automatic Electronic Defibrillators readily accessible; and a heart attack victim’s chance of surviving until the paramedics arrive to take over is now far greater.
The same principle works for defending against mass murders. It just doesn’t work here, because it is politically incorrect to employ it here. After the Ma’alot massacre in 1974, Israel instituted a policy in which volunteer school personnel, parents, and grandparents received special training from the civil guard, and were seeded throughout the schools armed with discreetly concealed 9mm semiautomatic pistols. Since that time, there has been no successful mass murder at an Israeli school, and every attempt at such has been quickly shortstopped by the good guys’ gunfire, with minimal casualties among the innocent. Similar programs are in place in Peru and the Phillippines, with similarly successful results.
