So i looked up burqa bans and found this:
http://qz.com/326086/the-places-in-the-world-that-have-a-bur... which basically only has 2 European countries banning it nationally, and just a few more who implement local bans or have attempted to ban it. Provided the constitutional religious freedoms we have in the US, it seems very unlikely that a similar ban would pass here. In terms of obscuring your face, there are anti-mask laws, but they really pertain to protests/riots.
I'm not suggesting that the ban is good, or other countries will not follow suit, however it just seems like quite a jump to make - because 6 countries have some form of a ban on a burqa we have to watch out for face recognition. Should we not wear a cross if we're Christian because Syria persecutes Jehovah’s Witnesses?
