He’ll be criticised no matter what he does but his point about using the right amounts of PPE in the right situations is a fair one. There’s a global shortage of the stuff, so it quite crucial to bear in mind the guidelines on when and how to use it. He’s also right to say that it’s impossible to criticise people for using it too quickly as they are of course worried/scared. But it’s part of his job to make sure our PPE supplies have the biggest impact on the nation’s safety that they possibly can, so he has to remind those using it to use it wisely. It’s a tough situation, but there’s nothing wrong with him saying what he did. Those criticising need to realise there aren’t PPE trees that we can just pluck the equipment from.
