A math teacher in Colorado (not far from where the infamous Colombine shooting took place a decade ago) tackled a shooter in his school before he could get very far in his shooting. David Benke of the Littleton middle school said he had no time to think as he took down a shooter who had already shot two students then was reloading to shoot some more. Benke and other teachers then held him down until the police arrived.
"Gutsy" and "selfless" doesn't begin to describe his heroic actions, and in honor of his brave deed, I give him my Real Life Superhero kudos. It goes to show that you don't need super powers to be a hero.
