Outdoor protests in June of 2020 said not to be a source of Covid-19 spread.

There isn’t evidence that Black Lives Matter protests have led to a noticeable increase in COVID-19 cases, despite early concerns from health officials.

The reasons for the lack of transmission likely have to do with the protesters being outside in the wind and sun and most of them wearing masks.

But 9 months later in April 2020:

Images of hundreds of largely maskless people crammed on to the Santa Monica pier or huddled around street performers on the Venice boardwalk over the past few days have raised concerns that spring break in the Golden state could spiral out of control, much as it has in Miami Beach, Florida, and trigger a superspreader event.

So which is it?

  • In June 2020, outdoor assemblies of people were not mass spreader events.
  • In April 2021, outdoor assemblies of people are mass spreader events.

These statements cannot both be true.
