Harrowing security camera footage has been released showing the moment an Oklahoma high school principal was shot in the leg while stopping a would-be school shooter in his tracks. On April 7, former student Victor Hawkins walked into the high school in Pauls Valley with a loaded gun. Within seconds, Hawkens was taking aim at two students, the footage shows. Police allege Hawkins, 20, yelled for everyone to "get on the ground," which prompted the two students to run for safety. Out of nowhere, Principal Kirk Moore is seen entering the frame and rushing towards the gunman.
