The lockdowns continued to lift without the appropriate countermeasures in place. It really is that simple. For Florida - May 18 was the beginning of phase one for reopening. June 3 is the beginning of phase 2 reopening. Then this timeline follows Almost exactly 2 weeks after phase 2 reopening, they start seeing record cases. There's not much else to it, they made almost no efforts to contain the spread once they started opening, contact tracing is non-existent, testing is slow...and it spread. Guidelines also say they should've stayed in lockdown for two weeks after cases began to decrease, which they didn't do. They haven't issued a mask mandate... There's just so many other factors than the protests which, like I said, even if it had an effect, it clearly can be contained as in New York. EDIT: I see you edited your previous comment. We see a much better correlation between states with good programs, following guidelines, being strict about reopening having better times than we do about protests. Even if I grant they contributed to some minor spread, I think we have to agree they are not the primary factor here. Different policies about the virus itself seem to have a much better explanatory effect than existence/size of protests.
