IMHO, I believe that Al Qaeda is already there and with a definite plan. Surround Paris then take it by storm. Those guys are looking at the high ticket items on the Champs Elysee. Al Qaeda needs the publicity right now for an upstroke on recruitment and show of force in Europe. I'd look for the boarding up of business in Paris soon if this rioting isn't handled, and I don't think it's going to be pretty.

More like the plan is to provoke a response that they can whine over as a justification for their bomb/whatever attacks in France.

Friday is the end of Ramadan. THIS IS THE TIME to expect attacks:

Then, when the sacred months have passed, slay the idolaters wherever ye find them, and take them captive, and besiege them, and prepare for them each ambush...
        Surah IX:5

And slay them wherever ye find them ... Such is the reward of disbelievers.
        Surah II:191
