200 Teachers Armed in Utah. (VIDEO)

Class was in session Thursday for about 200 Utah teachers who will get special firearms training — working with a plastic gun in a conference room at a hockey arena — to carry concealed weapons in their classrooms.

Since the Dec. 14 massacre of 20 children and six staff at Sandy Hook Elementary School in Connecticut and the National Rifle Association news conference touting arming teachers for school security, such classes are drawing fresh attention.
