I had a big argument with my partner on the evening of the 16 March, the day BoJo told everyone to stay at home, avoid non essential travel but didn't close down pubs/restaurants/shops.
We went for a walk and every pub we passed had loads of people in. I said we should be in full lockdown right now and this semi lockdown was going to kill people. She was of the opinion that people were fine to go for a drink and we shouldn't judge.
It was so obvious to me at the time and unfortunately I was completely right, with tens of thousands of deaths the result of BoJo acting too late.
This is why, for me, anyone acting like it is only clear in hindsight is a load of rubbish.
It was obvious, if you understood exponential growth and were willing to actually take the decision.
