I don’t think the Tories wanted or particularly believed in any sort of lockdown. No way do I think they’d prioritise saving people’s lives or preserving the NHS over the economy. I think they left lockdown too late for it to have a worthwhile impact. They then just did what the rest of Europe were doing, but in a confused and tiery way. They wanted to be Sweden. That’s why they partied through it.
Scientifically, I think lockdowns to stop the spread of an uncontrollable and deadly virus can work (Ebola in Africa). But quickly, decisively and as a short term measure until the virus is under control.
