From what I’ve read, Seine-Saint-Denis is a no go area for all but the sandmaggots. Cops, fire, Frenchmen don’t go there.
I hope the army goes in full force, not just the Surete. Perhaps even blockade the ‘bainlieue’, no one in or out, no food or water in. Turn over the maggot or else. Period.
They need to send in some tanks.
