Copé has been pushing this initiative and advocating for a complete ban in all public places, trying to out-Sarko Sarkozy, if you will (a tall order, admittedly).
This is how a small number of women (400 burqa wearing and another 1500 wearing a niqab "integral" veil) become a danger to the Republic as we know it.
