Yeah, the date made me laugh also. But I suspect it has more to do with the fact that April 20th is the first day after the Easter school vacation in most states.
I expect things to begin to return to normal as we approach Easter. I think most figure out that this is BS and I believe with the approach of nice and warmer spring weather folks are going to head outdoors regardless of what the powers that be dictate.
And the authorities cannot have the public blowing off their dictates.
Like in the states, the pols here have been driven by the panic induced by the media and magnified by social media. The crowd was “demanding” a solution so they got it.
The good that will come out of this will be that the people realize that not only can they not trust the organs of the state (public TV, radio) but also that social media is not always their friend.
