There is only one authority to which the ministers can turn for questions that concern public health. They are therefore behind it (at least to the outside world). If the RIVM takes the one and a half meter rule seriously, only one advice can be expected:
"Amsterdam moet twee weken in lockdown."
If that is not necessary now, after having seen 5000 men packed together, then there is really something wrong with this rule. They can hardly bet that not one of the 5000 people present was infected.
Now suppose that in a week or two nothing appears to be wrong in the capital and surrounding areas, what does that mean for the entrepreneurs who have seen their turnover decimated because they do adhere to the rules? For the boas who have been handing out fines? For the citizens who have paid fines?
Het RIVM-oordeel "Amsterdam moet twee weken in lockdown" kan een escape bieden want als er dan niks gebeurt, is tenminste "dankzij de lockdown een uitbraak voorkomen".
Without a lockdown, an outbreak almost MUST occur, at least if we try to understand what is behind the guidelines. According to the RIVM, face masks are only effective in public transport and their one and a half meters was not respected. Hands were not washed and how the sanitary facilities were arranged while 350 people were counted on I can only guess.
It is a nice paradox: only a corona outbreak can save RIVM from this. I am already satisfied with a small Amsterdam corona wave within two weeks. At least then it hasn't all been completely in vain.
