As I said upthread, it's very simple, you just have to pick up the code words used by the euro press:
Student = White Elite Native French
Protestor = White Elite Native French
Youth = North African Muslim Immigrant (or child of immigrants) from the Banlieus (suburban slums/projects)
Once you catch the jargon, it's simple. The Youth are just there to steal from and beat up the Students/Protestors. Later, the Youth will have their own senseless riots, burning cars and buses, etc. But right now they're busy preying upon the Students/Youth.
