A company in Atlanta makes a bulletproof bookcase designed to protect students during a school shooting.

It comes as protective equipment is in demand, while gun control advocates wait for stricter legislation.

The bookshelves are real shelves, but are lined with Kevlar along the back and sides -- and can act as barricades for the classroom door.

The CEO of ProtectED Solutions LLC says once there's a lockdown, the bookshelves just need to be pulled from the wall, lined up and locked into place.

They are already in some schools around New Jersey, and may find their way into churches.
