A high-school teacher in Medford, Ore., is suing for the right to carry a Glock to school.

Her ex-husband, she said, has threatened her life. She's already done what the experts advise: had him arrested for what's known down there as "menacing." Filed a restraining order. Told family, friends and anyone who would listen that she worries for her safety and that of her two kids.

Then she took the required classes on handling and firing a handgun, and got a concealed-weapon permit.

School officials found out and, understandably, forbade her from packing heat along with her lunch. If she did, they said, she'd be fired.

So today the teacher's lawyer, James E. Leuenberger, will ask a judge to remind the school district of an Oregon statute that allows concealed weapons in all public buildings except courthouses. (Washington law prohibits teachers from carrying firearms on school property.)

The 44-year-old Oregon teacher — who wishes to remain anonymous and is not named in the lawsuit — called the school's policy prohibiting guns "fear-based."

A school without guns, she told me, is a vulnerable school.

Look at Columbine, she said. One teacher with a gun could have changed the ending there.
