Anything fully covering the face in public- including Islamic niqabs and burqas, not hijabs which show the face- are banned in France. It's the law. And yet there are those who refuse to comply. The arrest in a Paris suburb of a 21-year-old Muslim convert who allegedly tried to strangle a police officer after the cop told his burqa-clad wife to remove her veil has spawned the typical violence in Paris banlieues including Trappes.
There's been the usual mob violence including stone throwing and setting cars on fire, and the denial of guilt. We can probably expect more of the same in the days to come.
