Why some Ohio school districts are arming teachers and staff with firearms

In 2017, West Liberty-Salem High School in Salem, Ohio, joined the list of schools that have experienced a shooting. The only visible scars are bullet holes in a bathroom wall, but the psychological trauma still lingers.

"Later on, they got the good news that nobody died, but their brain had already experienced that traumatic experience," said principal Greg Johnson.

In that bathroom, Johnson and fellow principal Andy McGill rushed to help a student who had been shot twice, with the shooter just feet away. McGill was able to talk the shooter, another student, into putting the gun down.
