A high school principal in Pauls Valley, Oklahoma, was shot in the leg while confronting a former student who entered the school with a gun, authorities say. Principal Kirk Moore and other staff moved quickly when they spotted the armed man in the lobby, and their actions prevented injuries to students — no students were hurt, and the suspect was taken into custody. Officials, including the governor, praised Moore’s bravery and noted his prompt actions helped keep others safe. Moore is now in stable condition and expected to recover.
