This news clip from Belgian TV reports that a crowd of “youths” in Liège went on a violent rampage after one of their number was shot and killed by a jeweler during an attempted robbery. The young scalawags engaged in the usual youthful hijinks, hurting people, busting up cars, etc.
The newscaster carefully dances around the ethnicity of the villains. Take a look at the brief still photos of the gang as they flash past on the screen, and make up your own mind.
