I totally agree with you that the people in charge are complete idiots and and largely to blame for the situation we find ourselves in. The decision not to restrict travel into the UK from countries earlier in the year, a lockdown brought in too late, the Dominic Cummings eyesight test, attempting to force children back to school before the September break, the eat out to help the virus, Johnson telling people to get back into the office and then being forced to backtrack as infection rates started to increase.
Falsely raising people hopes regarding Christmas was incredibly cruel and stupid. It looked like we were heading for an absolute disaster following Christmas and the brick of reality has hit Johnson full in the face. The so called recent discovery of this new strain has given the Government an excuse to back down and whether this new strain is largely responsible for the spike in cases is debatable, however the fact remains that cases are increasing at an alarming rate. More importantly it has dealt the Government a get out of jail free card and has forced them to do the right thing albeit in a characteristically bungled way. Johnson not loosing face is far more important than peoples lives.
Raising infection rates are not just down to Government incompitence though, the population also has a crucial role to play. The virus is spread by person to person contact, that fact has been consistent right from the beginning, thats not difficult to understand, even if advice from this bunch of idiots has been. The advice and rules brought in by the Government have been contradictory and confusing to say the least, but the same cant be said regarding advice from the medical advisors which has been largely consistent throughout this, apart from the wearing of masks in the early stages. The Government has clearly ignored the medical advice on numerous occasions.
The scenes at London Stations are not entirely down to the Government though and is a little naive if you don't mind me saying. Many of those people packing those trains have decided that their Christmas will not be disrupted no matter what. The announcement on Friday would have come as a bitter disappointment to many but these are adults not children. It appears that many people are prepared to put themselves and other people, including those people who need to use the transport system to go to work. People traveling to and from work being told being told that social distancing would not be possible and advised to not travel if they feel uncomfortable. This is not an isolated incident either, just cast your mind back to the summer and the bank holiday weekend. Beaches and other tourist spots rammed full despite people being asked not to travel. The timing of the announcement and the fact that the tier 4 and restrictions should have been brought in with immediate effect was a glaring act of stupidity but that doesn't excuse the stupidity and deliberate acts of individual selfishness by people who are not prepared to have Christmas disrupted.
