Some teachers in North Carolina are signing up for classes to carry concealed guns.

It comes in the wake of the mass school shooting in Newtown, Conn.

A combat center in Cary started offering free gun training courses after the shooting at Sandy Hook Elementary.

The gun center said so many teachers are signing up that there’s now a waiting list.

“Ever since we posted that we’re offering free classes for teachers, we’ve been absolutely crushed, inundated.  Teachers want to learn about firearms,” said Molotov Mitchell of Triangle Krav Maga.

Some gun rights activists have been lobbying North Carolina lawmakers to allow teachers with concealed carry permits to be armed on campus.

There’s a similar bill proposed in South Carolina.
