I will answer your question with a question:
Is Trump accountable for the outbreak because he down played it in February?
I believe that no one clearly understood this virus and how it worked, especially now that we know China was not forthright with the virus in the first place.
Trump could have done a lot more preparedness than he did, but that is why I used the the phrase “Hindsight is always better than foresight” because I believe people try to make the best decisions as they can with the knowledge they have. Sometimes they make bad decisions, that is called “life”.
Of course, Trump Gov. Cuomo and all elected officials are accountable for the decisions they make “right or wrong”. That is up to the voters to decide on what level they hold them accountable.
I heard (not verified) that Cuomo belief was to putting people in nursing homes type places was because they had 24 hr care and it would isolate them from the general populations of hospitals.
Like I said, some decision are not the best made one. Every elected official makes bad decisions it is part of life.
It is easy to set off to the side and judge other people when you are not the one accountable for the health and safety of the people.
