If only
There's a reason prayer is illegal in schools. Even if the students initiate it and it's not "required". In the northeast or on the west coast, the ones doing the praying would probably get some funny looks, but mostly they'd be ignored. In the bible belt, kids who don't join in get bricks through the front windows that night. That's if they're lucky enough not to just get beat up after school.
So sure, it'd be great to pass a law saying you can't require someone to wear a burqa. Then, when you want to prosecute a violation, all you have to do is find a witness willing to testify against her family.
