What do you mean, it's all over now?
If you're referring to the lack of criminal prosecution, that can't really surprise anyone. The police had to investigate because complaints were made.
The Guidance about not leaving the house was not enshrined in law. There can be no evidence that would substantiate criminal prosecution for driving 60 miles, with your 4 year old in the car , as the only way to check out your eye sight is good enough to drive almost 300 miles back to London.
So - no surprises there.
The issue isn't about law, its about morals and ethics. Its about a public servant setting an example, by following the guidance he helped to write. It's about a morally bankrupt Prime Minister.
