A group of teens willingly stood against a wall and got a dose of pepper spray to the face as a part of a criminal technology course at Barberton High School in Ohio. In a video circulating online, students are seen lined up against a wall. One by one they get sprayed in the face. Eventually nearly every student is screaming. A schools spokesman said the spraying is sanctioned through the Ohio Department of Education. The exercise is supposed to help students who may be going into law enforcement understand the effects of pepper spray. Each student who took part in the exercise needed a waiver signed by their parents.
