Possibly DC didn't break any rules or laws but he certainly bent them. His wife called him home as she thought she had Covid19, but the same day when she felt better, not knowing if she had it, he returned to work, when the rest of us were told if any one had symptoms we were supposed to self isolate. They drove 250 miles with her still showing symptoms - weren't the police at that time given the powers to escort anyone showing symptoms home? After his son was taken to hospital and whilst he was still suffering from what he says was the virus, he left the house to drive and pick them up. Even if he didn't leave the car, if he was as ill as claimed, he was a danger behind the wheel.
There was no need for them to go for a test drive, as his wife drives - something she has mentioned several times in articles, so could easily have taken over driving home.
I think what people are so angry about is the fact that majority of us have sacrificed seeing family and friends, have missed holidays, weddings, funerals etc because we thought it was right and now we find that we could probably have found loop holes and done these things! How many parents have struggled with child care when ill, because they didn't realise they could have driven to family?
A simple admission of an error of judgement when all this came out and an apology and a sign of some regret would have gone a long way. Instead we get none of that, even arrogance yesterday keeping the whole Nation waiting half an hour!
