Within living memory, Southern Nevada high schools had rifle ranges and competitive shooting teams. Kids brought their .22s to school and no one thought much about it.

Up until 1989, Nevada had no restrictions on teachers carrying weapons in the schools, according to state Sen. Bob Beers. To this day, teachers can do so with the permission of a school's principal, he says, while California, Oregon and Utah manage fine without even that restriction.

Yet Sen. Beers now seems to have stirred up a swirl of controversy by merely proposing that Nevada schools be taken off what he calls the list of "easy terror targets" by again "allowing" teachers to exercise their constitutional right to bear arms.

From the response in some quarters, one would think the senator is proposing that teachers be encouraged to shoot any young person who forgets his homework. Yet there have been no reported incidents of teachers harming their students in jurisdictions where they regularly go armed, such as Israel.

Sen. Beers' proposal -- Senate Bill 286 -- would allow teachers to exercise their Second and 14th Amendment rights only after 40 hours of specialized training -- five times the amount required for any other Nevadan to a acquire a permit to carry a concealed weapon.

Nor would any teacher or school employee be required to go armed. The authorization would be "volunteers only" -- and it's a safe bet that of the few who apply, many would be ex-military or ex-police.

Hundreds died when Islamic terrorists targeted a school in Russia in September 2004, Sen. Beers told the Senate Transportation and Homeland Security Committee on Thursday. Terrorists may have no dearth of potential targets, but "I can think of none that combine such an extreme degree of vulnerability and pricelessness as our schools and our children," he said.

In the Middle East, Arab terrorists once targeted Israeli schoolchildren as easy prey. But after the Israelis authorized both teachers and parent chaperones to carry guns (thus "hardening the target") only one group of Israeli schoolchildren has been subject to such an attack -- on a day field trip to the Jordanian border for which they foolishly agreed to leave their guns behind.

Sgt. Bob Roshak of the Metropolitan Police Department spoke against Beers' proposal Thursday. "We really don't feel that schools are the place for handguns to be," Sgt. Roshak said.

Sure, it's easier to spot bad guys if they're the only ones with guns. In totalitarian states, where "civilians" are disarmed by law, they're generally the ones still standing amidst the piles of bodies.

American schoolchildren and a teacher bled to death inside Columbine High School in April 1999 after their two assailants merely waited for the on-duty "school policeman" to go outside and sit in his car for an early lunch. No student, teacher or administrator inside that Colorado school had the means at hand to fight back and stop the attack.

But in a similar school shooting in Pearl, Miss., in October 1997, Vice Principal Joel Myrick responded quickly to the sound of shots. Luke Woodham had slit his mother's throat before carrying a .30-30 deer rifle to school that day. Woodham fatally shot two students as Mr. Myrick dashed to his truck -- parked more than a quarter-mile away as required by law -- to recover and load his own Colt .45. He then captured and disarmed Woodham, holding a gun to his head for more than four minutes while waiting for police to arrive, thus almost certainly saving lives.

So an armed American teacher has already saved lives, on an occasion when the police couldn't possibly arrive in time -- but only after other children died while he was obliged to run an 880-yard dash.

Patrick Boylan, a former member of the Nevada State Board of Education, congratulated Sen. Beers on his proposal Thursday, pointing out that floor plans of U.S. public schools have been recovered from terrorists in Iraq. "I commend Sen. Beers on taking such a risky move," Mr. Boylan said. "But it's about time we sit up and protect our children."

Mr. Boylan is right.
