He wasn't talking about students, either, who are hardly a minority, BTW. He was talking about a handful of unruly citizens, who arguably are criminals. There was a huge coke bust in the neighborhood in question (Sagewood), along with some reports of gunfire, assault lots of breaking and entering and a few stolen cars and a number of other issues, in addition to the noise, garbage, speeding through neighborhoods, drunk driving and so on.
If my son or daughter was a student here and was living on Sagewood, I'd be terrified. No metaphor is too harsh for that slum.
