//He did his job correctly.//
Did he?
“A spokesman for Milton Keynes Council said: "We are sorry to have upset this family. We don't usually step in if a guest needs to be comforted by another family member and in this instance should have taken a more considered approach.”
//So are these rules, laws, advice, or just something the government can announce then encourage people to ignore?//
The face mask episode you mention involves the commission of a criminal offence. It is not within the power of shopkeepers or Local Authority staff to enforce the criminal law. The relevant regulation describes who is responsible for such enforcement:
In these Regulations—
“relevant person” means—
(a) a constable;
(b) a police community support officer;
(c) in relation to any transport hub from or to which a TfL public transport service is provided, a TfL officer;
(d) a person designated by the Secretary of State for the purposes of this regulation.
The “distancing” guidance is precisely that – guidance. Nobody commits a criminal offence if they sit too closely to their mother whilst she attends her husband’s funeral. It is not in the crematorium’s remit to prevent it. They should only make reasonable accommodations for the guidance to be observed. There are huge problems with this nonsense; the people tasked with facilitating social distancing have taken it upon themselves to enforce it. It is simply not their responsibility to do so. In fact it’s difficult to establish whose responsibility it really is. This individual behaved in a ridiculous manner. It may not have been his fault - it depends what his instructions were. Though the Council’s comment (“we don’t usually step in if a guest needs to be comforted by another family member”) seems to suggest he was instructed to exercise discretion in what were sure to be delicate circumstances at times. But the virus matter has demonstrated that the “rules” or “guidance” or whatever are being seriously confused with the law. That’s the fault of the legislators and politicians and it needs to be sorted out.
The virus crisis has produced some remarkably stupid reactions from both individuals and corporations. As I keep saying, the virus will spread and all the various measures are doing is simply elongating the period of that spread. Preventing a son from comforting his mother at his father’s funeral will not alter that.
