The whole of NYC isn't a ghetto, but the PC buttwiopes who run the school system have made it so, and have turned a blind eye to the racial thuggery.
An adult world? These were two kids in a public school in which "enlightened" liberal policies have created and perpetuated, penitentiary like feral behavior. You don't like the truth? Too bad.
The parents of these kids thought they were someplace where they weren't. I have no idea what you mean by "racial thuggery." Things really are what they are sometimes.
