I'm not missing any point, you said people, 2/3 weeks ago "had" to x y or z... no they bloody well didn't, it was advice, like eating 5 a day or sticking to 14 units per week..... pretty much ignored, just as most govt advice is ignored
They were told to isolate. The advice from nhs direct was 'if you returned from italy on or after march 9th you must isolate regardless of wether you have symptoms or not.' The word MUST means it they were told to the MUST. The fact that people didnt is by the by. Just like people, are ignoring the current rules. Or are you saying the lockdown we have is just advice too?
There was little in place 2 or 3 weeks ago, you can try and re write history but we all heard the PM stating its fine to shake hands & the Cheltenham festival went ahead, as did that weekends football.
There was little in place? So there was something. That's not nothing. Social distancing started march 4th. See the earlier link.
The fact that cheltenham went ahead when other things were cancelled doesnt mean anything. It should have gone ahead they expected smaller numbers and thought people who were sick wouldnt go. It doesnt appear to be the case.
The fact is, there were things in place. People returning for certain countries were isolating. People with fevers and coughs started to isolate 2 weeks ago. Not enough to reduce numbers now and maybe not enough overall. But to say there was nothing in place is rewriting history.
