It is erroneous to say “science doesn’t support re-opening this early”. Science simply suggests that opening this early will cause a large number of otherwise unnecessary* deaths and a likely shortened and more painful lifespan for some of the survivors.
Politically, this needs to be balanced against other critical factors, like the availability of haircuts** and stock market indices. So it’s really a heads vs tails sort of thing.
* Don’t get me started on the concept of “necessary deaths”.
