“Our findings suggest that any direct decrease in social distancing among the subset of the population participating in the protests is more than offset by increasing social distancing behavior among others who may choose to shelter-at-home and circumvent public places while the protests are underway,” the report reads.
So based on what we can tell, people protesting outside in open air (with a lot of masks as far as I could see from the pictures) causing everyone else to stay home leads to a better outcome than people doing stuff inside buildings together. That seems to line up with the facts we’ve been hearing.
