The only reason politicians are deferring to experts is they've realised experts are actually useful whereas before they didn't like them (something about the time for experts is over, something like that, can anyone recall?)
Conversely you haven't touched on the fact that the buggers are constantly spinning, deferring blame for not getting enough PPE, plain deceit about the number of tests done etc.
The UK has not done well. That was avoidable. If you defend that, you let the responsible ones off the hook and they will do it again.
