I am not intending to make a political statement:-
There have been a series of high profile personalities who have taken decisions to act against the spirit, if not the law of the lock down regulations. Some have paid the price for their actions.
Whilst some of the actions may have been technically legal, they may not have been prudent given the position the person holds, and the public's sense of decency.
Headline titles of regulations give the flavour what whats contained in the regulation, and for most casual users that will be enough, but if you dig down into regulations you will often find there are certain limits, exceptions or loopholes. Often it is only the people who have time or enough money to spend to find these loopholes that can use them and by doing so they look conspicuous and apparently breaking the spirit of the regulation.
Until you have all the specific information (and I'm not claiming that public statements give all the exact information) you cannot judge if their actions are permitted given the specific conditions.
Edit 29th May
We now know the police have reviewed the latest high profile persons actions and on the count of driving 250 odd miles to provide child care and self isolate was not illegal, but the 60 mile round trip to verify eye sight was a minor infringement and not going to be taken further.
In the public's eye view which is fuelled by some of the media seeking "stop press" headlines, the credibility of the government has been dented.
In relation to this pandemic, the big problem now will be a significant number of people who becasue they have seen high profile people apparently breaking the regulations and safety advice, they take actions but for perhaps the wrong reasons.
We have already heard of large gatherings of people in excess of the Government guidelines, and who are ignoring safe distancing advice. I can see their self gratification actions putting more "at risk" people in greater danger of catching the virus.
This is another classic example of how inadequate "common sense" really is and how selfishness is rife despite us all facing this pandemic.
