When a student shot a gun on his high school campus, other students were terrified… but then a hero stepped in.

Brady Olsen teaches government and civics at North Thurston High School in Lacey, Washington. On Monday, April 27, 2015, he heard a loud noise near the school’s common area. As he and a couple other teachers approached the stairs, he saw a student walking down it, smoking a cigarette and carrying a gun.

Olsen stepped sideways behind a pillar, and the shooter let off another shot. Immediately, Olsen took action and lunged at the shooter.

Olsen describes his experience in this video clip. You won’t believe what he said to the shooter as he had him pinned on the ground…
