I don't think anyone is completely to blame for anything. Honestly, i think it is too early to know if we have done enough or not at this point. However, I don't think The office of the President had a multitude of information that was being withheld from Mayors and Governors across the country. They were all free to make decisions about their states and cities, despite what was, or was not, being nationally.
Many keep saying it was obvious what was coming based on cdc and other stats months ago. If this were the case, why wait on a national directive, particularly in densely populated metropolitan areas like NYC. Nobody was stopping Governors from shutting things down earlier just like they are now. What is going on nationally, is only a collection of events happening locally(state by state).
Just for the record, I may disagree some with this particular post, but you have been very level headed and reasonable with your comments/assessments regarding this situation to date. Even when you disagree, you just present your case and never attack the other person, which is to be commended. Unfortunately, that has become more and more uncommon.
