Let me make sure I understand you correctly.
The French are so passive that it took an American summer student to demand corrective action ?
It was true. My fellow Americans & I were appalled at the laisez-faire attitude of the French, in general. A few were upset -- especially at the Socialist system that supported these people -- but I guess most of them figured as long as the Arabs bothered only the non-French & not them, they were fine. Basically, they were trying to ignore the fire in their backyard.
Of course, this was 30 years ago. I sensed even back then the Arabs would be a problem. I think the French have finally woken up, but unfortunately a bit too late.
