Schools bag purses.

The purses slung over the shoulders of many teenage girls are growing in size, and so are security concerns. In an effort to keep students safe, high school administrators in Minnesota, Kentucky, Florida and elsewhere are now banning purses from classrooms, saying that they can be used to hide weapons or drugs.

There are no statistics on the trend, but according to the National Association of Secondary School Principals (NASSP) more schools are restricting purses to lockers, just like backpacks and other large bags.

But students and educators alike acknowledge that this is not a surefire way to keep prohibited items off school grounds.

Abby Kowitz, a junior at Fergus Falls High it School in Minnesota, says the new policy is "kind of pointless." "If someone wants to bring a weapon to school, not being able to carry a purse won't stop them," she says.

"If they're in a locker, I'm not saying it couldn't harm somebody," says Michael Blevins, principal of Conner High School in Hebron, Ken., "but it would have decreased the amount."
