Intrepid journalist wrote in MEN the Saturday following debacle over Jack Straw's admission to asking these women to show themselves so that he could relate to them via his own culture and upbringing.
She donned a veil and drove to the Trafford Centre. As I recall from this piece .. she felt claustrophobia from breathing through fabric but claimed her vision was OK. Her photo in niqab as per MEN was not as concealing as the sacked teacher's by the way.
Her verdict was that she felt unable to communicate.. but did feel "anonymous" despite the glances in the shopping mall.
I guess it depends on the style of this garment as they do vary.
My personal view: Like Jack.. I want to see my patients and will request I do see in order to treat properly. I will have a female nurse present and if I can .. one of similar faith so as to show I do understand. but..
Usually they comply as they want to live

after all. But I do try to be as understanding and gentle as warrants my position.
I see nothing wrong in requesting verification of identity and do question why they need to wear a veil when we have an automated enforcement policy which more and more relies on photographic evidence.
Perhaps we should all wear these veils.

I wonder how we'd prove who was driving what then ..

But that's illegal.. but I bet a lot will use it under the "ping and not bother checking insurance, MOT, and simply requesting naming a driver .. which as we see leads to severe injustice at times.
Bring back them police. We need 'em!
