There's a reason most shops and schools are opening up again in June and July. The Government has not only realised just how badly Neil Ferguson got it wrong, they also know that the public are quickly running out of patience with them. It's become obvious now that Wuhan-Flu is not nearly as dangerous as we thought, and no amount of media hysteria can change that.
In all honesty, I hope lessons are learned from this. In so far as the Brits will distrust big daddy government a good deal more, and perhaps ask why it has so much power in the first place. A man can dream.
