Believe me, they SAW. They just turn a blind eye to it, becasuse they want to see if your kid will hit back. A coworker of mine had a son who beat up four kids who jumped him. The teachers admitted that they saw it happened, but were furious at the kid for defending himself. My coworker pulled the kid, sent him to the local community college and the kid got his G.E.D. 6 months prior to the high school graduation.
