1) Sending the elderly back/in to care homes without testing them, further spreading the virus to the most vulnerable.
2) Pausing all community testing despite repeated warnings from the WHO that they weren’t doing enough, lying about a lack of reagents being the reason and then later admitting that it was a policy decision to focus on hospital admissions only.
There’s a couple for you to get started on. The idea that the government prevented the NHS from being overwhelmed is laughable. It’s funny how they didn’t show off how much spare capacity there was in hospitals until after they’d cleared out all of the elderly and opened the nightingale hospitals. Almost as if the existing NHS networks were at breaking point.
