While the briefings themselves are piffle waffle nonsense (and probably Saint Boris's personal highlight of the week, because he gets to play the clown for a few minutes, in the boring job of being PM), one good thing about all this is that the government is being forced to do something about their own mess.
If the government deliberately exaggerated the new strain of the virus (which I strongly suspect they did, to scare people into not mixing at Christmas), their crying wolf is coming back to bite them. We had the border issues, and now the teaching unions are taking the governments placard waving "Ooooooooooooh, the virus just got a whole lot more deadly!" seriously. Also, I think the government chose now to announce the school closures, while people were still in "holiday mood". If they had announced it before Christmas, people would probably have rebelled angrily by mixing over Christmas.
The public mood is fickle: right now, they are screaming "Close the schools!", and Boris's main strategy seems to be to do whatever he thinks the public wants. After a lack of school for a week or two or three, people might then start pleading for the opposite to happen; the government will do their U-turn, and a handpicked scientist will be bribed into saying "actually, having observed it, the new strain is not as bad as we thought. Back to school!"
@itsgettingweird And yes, it's the way the government is hiding everything, gaslighting, and lying that is really criminal, and that's what we really need to be getting angry about. That fight needs to go on after the pandemic has eased: that what we're really angry about is the deception behind everything. If their campaign wasn't so full of lies and doublespeak, I would have respected lockdown much more. And I still haven't forgiven Bliar for lying about weapons of mass destruction. That's the bigger issue: why do tolerate so much deception by the government, whose wages we pay?? Ordinary people get sent to prison for lying about much less (e.g. who was driving a speeding a car).
