I wish someone would explain what they mean by a full lockdown.
Cafes,pubs,shops,hairdressers etc and schools are shut already for millions of us.What other measures do you want?
It isn't working. People are not staying home. As people have said already, people are out for click and collect, mixing with others, travelling to adjacent tiers to have a meal or walk around the shops etc. It's a shame the government don't show those traffic graphs that they did in the first lockdown - I'm pretty sure they would show a minimal impact of going in to Tier 4 compared with the impact of the 1st proper lockdown.
We end up with a see-saw effect - cases down in one bit of the country, and then up in another part - unless you have a hard border at the edge of Tier 4, cases will continue to spread and rise.
At least with a National Lockdown, there is a very clear message to everyone - Stay Home. No misinterpretation of the rules, no misunderstanding, and easier to enforce.
The economy can hardly be thriving anyway, surely? Those of you in a region with low cases currently - you are not protected from the impact of rising cases elsewhere. Your hospitals will get transfers from the overcrowded ICUs in the rest of the country. It's happening.
