//i honestly dont understand that attitude of someone else did the wrong thing,...//
Let me explain then.
It's because the person who "did the wrong thing" was instrumental in signing into law some of the most Draconian measures ever seen in this country. His name and signature appeared at the bottom of the document which provided for harsh criminal sanctions for transgressions which were made criminal offences when they were previously just things we did in everyday life. More than that, that same individual had been banging his tub incessantly for over a year, telling everybody how important it was that they complied with his instructions (which he made very clear, were not "requests").
Most people dutifully complied because they thought they were doing the right thing even though in may cases compliance caused them huge inconvenience and often personal heartache. One of the very worst things, he said, for the transmission of the virus, was for people of different households to mingle indoors. So you couldn't invite a neighbour in for a cup of tea. Then it transpires that the man himself who had signed the orders had broken the rules in the very way he told everybody they must avoid at all costs. So why, people now ask themselves' should they believe the blood-curdling warnings he has issued over the last year, designed to "protect the NHS", when he obviously doesn't believe them himself?
Now do you get it?
