In a tiny Texas town near the Oklahoma border, children and their parents don't give much thought to safety at the community's lone school.
That's because some teachers are carrying concealed weapons.
In remote Harrold, the nearest sheriff's office is 30 minutes away. So the school board voted to let teachers bring guns to school about five years ago. They must have a concealed-weapons permit, and each employee also must be approved by the board.
In the awful aftermath of last week's Connecticut elementary school shooting, lawmakers in at least five states have said they'll consider laws allowing teachers and administrators to carry firearms at school.
Texas law bans guns in schools unless the school has given written authorization. Arizona and some other states have similar laws.
