While the French loafers are rioting the Muzzie are prowling throough the mobs picking out easy "marks" and beating them senseless. It reminds me of a pack of wolves culling the herd.
There's a special vocabulary used in all the media reports/captions: "Youths" means Muslim thugs from the suburbs (read slums); "Students" or "Protestors" means native French upper class whiners. Once you know that vocabulary, you can begin to make sense of what you see and read. The Youths prey upon the Students. The Students whine about the Government.
