Yesterday, wearing a burka was made illegal all over France. First arrests happened today: http://www.english.rfi.fr/france/201104 ... test-paris
I'm pretty ambivalent over this ban. While I think it's disgusting that anyone should be forced by their religion to cover their face in public, I also think that people should have complete freedom in what they wear (if anything).
There's also legal reasons, wearing a burka conceals your identity as well as any other full-face mask, though it's safe to say it'd be a minority.
