I finally got my facts straightened out, and this is the whole story.

The first fight was some shit between Puerto Rican's and Dominicans, one of them punched the cop in the face. Somehow, the cops heard rumors of a shooting or huge gangfight between PR's and Dominicans the next day, so there were 14 cops. Now whenever there are always going to be about 5 cops in the school, and fights will turn to expulsion and jail time.
