Copuld this be local or is it something starting nation wide ?
This kind of thing has been going on in Southern California for more than 10 years. There have been numerous incidents of race war spilling into high schools, most often between blacks and Mexicans. The Mexican girls coordinate with cell phones and hold open doors for entry by Mexican gang banger boyfriends so they can attack other races...most often blacks. Whites have fled most public schools so there aren't enough white kids in most So Cal public schools to attack.
The authorities deny a race war, but kids on the spot know the truth.
This is "diversity" in action. Diversity=race war.
