I applaud the noble Lord for his advocacy of mask wearing, but of course this issue cuts both ways. He is right that we need to build back trust in sharing space with one another, but I am not sure that mandatory mask wearing either builds trust or erodes it. If we give people the impression that wearing masks is somehow a panacea that protects everyone on a tube train or in a lift, that is a false impression. Masks are not a panacea. In fact, for some people, they can be a source of grave concern and be enough to send them back home to seek safety. I take the noble Lord’s point that we have to be clear about this, but I am not sure that mandatory mask wearing, or even ubiquitous mask wearing, is either a universal antidote to the spread of the disease or necessarily builds trust in the manner he describes.
