Michael, the lockdown has reduced the death rate enormously; it has worked, and it continues to prevent infections.
But that doesn’t mean the restrictions can just go. Scroll down on the second link to Total Infected. It’s only between 4.2% and 6.9%, probably 5.38%. That means that around 94% of the population are still susceptible. If the restrictions were removed the infections, and subsequently deaths, would start going up like a rocket again.
We could replace the blanket lockdown with more intelligent interventions, such as millions of boxes of free masks everywhere, working four days on then ten days off, and lighter restrictions where there’s a lower infection rate. Here’s an interesting map for England and Wales:
