Maisie, you ask a lot of questions, people answer, you rubbish their answers, why?
Can you please answer a few questions as it's relevant to your post. If you have nothing to hide, what's wrong with ID. No one is so special they have no responsibility to their neighbour or country. Why would anyone living here not want to be part of the country they tried so hard to enter, think the rules have to be changed for them? We don't have X Ray eyes, can't see through a mask or a burkha, it could be anyone, just because they say who they are is not enough, why do you think it is? Is it at all possible you have answers. I would love yo know what job you have that gives you these insights.
