From GOPUSA:

Back in January, GOPUSA reported on Benjamin Srigley, a 39-year-old man who lives in Washington, DC. Srigley saw three pitbulls attack 11-year-old Jayeon Simon as the boy rode his bike. Srigley ran into his house and grabbed his handgun. He shot one of the three dogs. A nearby police officer heard the shots and once arriving on the scene, shot the other two.
