I'm not sure I agree with either of you. This is a fragile time and if the government doesn't act in a more invasive way the thread of the virus will not only threaten the economy as a whole but will affect everything else including more hospitalisation, more deaths etc. This period so close to winter is crucial, and the restrictions that Johnson imposed are no different to the ones that the public should have been following up until now anyway.
In order to prevent all the massacre that is to come, I feel tougher restrictions and better policing need to be put in place, as people are deliberately not following the rules.
The pandemic is already 6-7 months old in many of the countries and I don't believe that lockdowns will help in reducing the spread now. The virus is present in the air and the chances of getting infected are high even if you stay at home. I would say that at this point a fresh lockdown sounds completely unnecessary. It will have no impact in reducing the number of new infections, and on the other hand it will destroy the already weakened economy.
