This is pretty much normal for France. It has been going on for years. The only reason the big riots became news in the US is because of the sheer number of cars and buildings set on fire. USually, it spikes on New Year's Eve too.. with hundreds of cars being burnt. This also has been going on for years and never made it to the US news.
Do they bring marshmellows...oh, FRance, perhaps some Brie on the Hood. Hey what a great revolutionary song...
" Watch out for your Burka,there 's Brie on the Hood!"
Maybe the car burning is really a secret gov't program to prop up French carmakers?
France is a former republic and future Islamic theocracy.
