Oklahoma principal tackles gunman

The incident occurred on April 7 when a former student entered the Pauls Valley High School lobby with two semi-automatic handguns.

Principal Moore's quick actions likely prevented a much larger tragedy, as no students were injured during the attack.

Newly released surveillance footage shows the dramatic moment Moore wrestled the gunman to the ground.

The suspect, later identified as Victor Hawkins, has been taken into custody and faces multiple felony charges.
