Restive Youths Burn Cars In New Suburban Unrest
BAGNOLET, France – Restive youths in a Paris suburb torched a tourist bus and nearly a half-dozen cars and hurled objects at police early Tuesday, a night after fullblown unrest prompted by the death of a teen fleeing police.

Seems clear enough. Restive youths provoked by arrestive police lead to unrestive suburbs.
