Maybe that's the whole point? We know that an awful lot of people are now terrified of leaving their homes because the "stay home save lives" message worked too well.
Whatever the rights or wrongs of Dominic Cummings's actions, people will now start to think "well if he can break the lockdown guidelines, why shouldn't I?". Which can only be a good thing if it means we come out of lockdown a lot quicker.
Well if that was the point, then its certainly an interesting strategy to stage this story.
And how can it be a good thing to come out of lockdown quickly? A good way to start a second wave. Its good we are coming out of it slowly, rather than quickly.
