It sounds to me like they've reached a sort of gentleman's agreement, where the Muzzies will be allowed to burn down Paris as long as they don't threaten members of the French police force (23% of whom, according to another poster but which I cannot verify, are Muslim).
Actually, that's general Islamic jihad technique: hit and run. They blow things up, burn things down, set fire to or behead helpless civilians, etc. but rarely voluntarily engage in a direct confrontation with anyone they think could do them damage. Little Muslim chickens, being indulged by the French government.
