To be fair to the politicians, this is such an unknown thing to deal with. Yes, other countries have had it before is but in the grand scheme of things, the whole situation is relatively organic and given that it's a new virus and currently doesn't have a specific treatment, a lot of what is being tested globally is largely trial and error.
Yes people are dying. People die every day from flu like viral infections.
Regardless if it was wrong or not to go down the path the govt did, at least there was rationale there. There was a plan that was developed by leading scientists. Let's not forget that the UK has some of the world leading scientific bodies and institutions. The plan was based was risky and based on a number of assumptions.
It looks like they've quickly realised that a change in direction might be better so they're activating it. Is it still open to scrutiny - yes.
But given this is a total unknown that none of us have faced before, getting every decision right from day one (which we would hope and expect), just isn't possible when you're dealing with the unknown.
Stay safe peoples.
