You can disagree and "get it".
So, to be clear, this is Mr. Cumming's position:
I and my wife were unwell, likely both with CV19. I was concerned that this would result in a situation where we could not care for my child. I did not want to pass a potentially fatal illness to my wife's brother and sister who live close by in London. However, my 17 year old niece in Durham 260 miles away had offered to help. We felt her life was more expendable and the fact she resided on an opulent estate simply made this already convenient solution more so. We then made this journey in direct contravention of Government advice and I then returned to London to work also in direct contravention of Government advice. This is of course Government advice I was one of the prime architects of and has caused distress and suffering the country across as we attempted to control the outbreak of CV19. This is also Government advice that resulted in the resignation of Neil Ferguson, another architect of Government policy, for a lesser breach . Oh, and also, to test my eyesight I drove with my wife and child who I have already established the welfare of is of paramount importance, coincidentally on her birthday. I will then suggest that the Government advice did not relate to my circumstances, even though I was one of it's chief architects and suggest that the media are being unfair to me as I refuse to concede any wrong doing.
You're cool with all of this it seems. Most people aren't. You can "get" why I assume, whilst disagreeing?
