NY state 400K cases more than Italy, Spain and every other EU nation.
NY state 30K deaths > Italy. Slightly less than Spain. UK had 40K deaths but they went in for herd immunity before they realized such a Dead Granny strategy was unpalatable.
They didn't have to go to a full NYC lockdown March 2 (though they should have). There are intermediate steps that can be taken. The airports were an obvious danger point. They could have required a 7-10 day quarantine for all arrivals* (and then fewer would fly in). Hell, just simply passing out a mask to every single arrival as they stepped off the plane and into the terminal would have been useful.
I'm not saying it was all easy, and Trump and the CDC and WHO were all hindrances. But a confirmed case in New Rochelle on March 2 almost certainly meant that there were infected people in NYC by that date as well. The sooner you do a lockdown, with the fewest # of cases, the more effective it will be and the shorter it will last. You can lock down early or late, one is certainly preferable. A lot of wasted time.
* Kazakhstan was doing such in February, with people coming to your home to check your temp once or twice and calling every day to make sure you were there.
Otherwise I was under lockdown for over 3 weeks before I traveled to Europe. I wouldn't have met family members if I wasn't sure that the situation in Shanghai was well under control and that the quarantine was pretty effective (contact with almost no one for 3 weeks except grocery store workers in which both of us were masked, and I had a temp check to enter.
But of course when you deal with bankshot it's always going to be insults and he'll try to turn it into a smackdown, and his opinion won't change one iota, and he'll dig in and chew off your legs, and then chew off his own for extra practice, and then call them flesh wounds and start in again endlessly.
Anyway, I tried to provide some facts and timelines.
I think Cuomo made some wrong decisions and got stuck on Trump's timeline, to the detriment of over 1/2 million people in the tri-state area. Mostly, I think the numbers speak for themselves.
