Heroic actions bring change in tone on teachers

A spray-painted sign with the words “Hug a teacher today” hangs on a building in the Connecticut town where 20 children and six adults were killed at an elementary school.

It’s a testament to the teachers who sprang into action when a gunman broke into Sandy Hook Elementary School and opened fire. They hid students in closets and bathrooms, and even threw themselves in the line of fire. Some paid with their lives.
