If the last lock-down taught us anything when viewed across multiple countries it's that early harsh lock-downs lead to fewer deaths and can be eased sooner - probably with less effect on the economy.

It's looking like the scientists learnt that lesson, but not the politicians.

Having said that, politicians also know (more than scientists) that you need to wait until public opinion is on your side. A harsh lock-down three weeks ago might have led to lots of people ignoring it.
