They had been rising quickly before any of the protests took place and are linked with various states "opening up" too soon.
Like I've touched on in multiple previous posts, I don't think there's any good data to indicate that a phased re-opening in is a major culprit, much less the only culprit.
Let's review the timelines a bit for Florida.
They lifted the stay at home order May 5th -- no resurgence
May 10th retail was allowed to reopen with capacity limits -- no resurgence
May 15th restaurants were allowed to open with capacity limits -- no resurgence
As of May 25-26th, they were seeing two of the lowest "new infection days" since the whole thing started.
The George Floyd Protests started May 26th... (there's an average of 2-14 days of incubation before onset). 6/3, the major resurgence starts.
The narrative getting pushed is that "it wasn't the protests, it was the re-opening on 5/4"
That timing would be pretty coincidental...
It's especially coincidental that the timeline is almost identical for California, who wasn't been "recklessly reopening too soon"...they've kept everything closed, imposed curfews, even prevented people from going to the beaches...almost the exact same trend for Arizona as well.
It's either one big coincidence that the resurgences started occurring in so many places (some strictly locked down, others not) right in the exact window of "incubation-to-onset" from the date of 5/26. (which would mean they'd start becoming symptomatic between 5/28 and 6/11).
This is a case where they're going to have to pick a narrative and stick with it. Either the protests weren't at all the cause, and it was just a coincidence...but that would mean that large outdoor gatherings isn't a big risk for transmission, at which point, they have to admit they make a mistake by stopping people from going to parks and beaches. If 1,000 people all packed in on a city street yelling isn't a big transmitter, then there was never any reason why 5 friends couldn't meet at a park for a picnic or in someone's back yard for a cookout.
If the protests were the cause, then they'd have to admit that by bashing phased reopening, but not mass protests, they were "playing politics with a deadly virus" just as they've accused the republican governors of doing.
