Why are they rioting?
I'm sure we've all read this many times before:
"I've always loved visiting that part of the city. The people are so nice and friendly, and I feel warm and safe whenever I go there. Now I hear that those people are rioting. They must have very legitimate and severe grievances if they're willing to engage in so much violence."

Actually, I've never read that. Incredibly, I have often read:
"I've always dreaded visiting that part of the city. Vicious gangs control the streets, and even the police are afraid to go there. Now I hear that those people are rioting. They must have very legitimate and severe grievances if they're willing to engage in so much violence."
