We had a court case in Australia, cop was trying to ID a niqab wearing driver (btw wouldn't driving in a niqab impair vision? I dunno...) anyway, in a statutory declaration she accused the cop of trying to rip the niqab off her face, which turned out to be a lie when the dash cam footage was released.
She was given six months for deliberately making a false statement but her attorney appealed on the grounds that they couldn't prove it was her under the niqab making the statement, and the supreme court upheld her appeal.
So now, in every state, cops have the power to remove any head dressings to confirm ID
