An extraordinary documentary called "Bully" captured a behavior adults hear about, but rarely see: the way some kids pressure and relentlessly harass their peers.
Filmmaker Lee Hirsch was embedded in several schools for an entire year. What he filmed was so raw and eye-opening that the project catapulted a movement, sounding the alarm about the critical and dangerous issue of bullying.
