I was thinking about the outside issue. It seems in general this is quite protective, presumably because the wind blows the droplets away, rather than their being recycled in a largely air-tight room. But for a sufficiently large protest, presumably the wind is blowing them away… onto another part of the protest! So I worry that this factor will be less protective here.
Great explanation of the scaling issues, good way of thinking about it.
A protest near me had six foot markings on the ground to give each individual protester their own box… which was then ignored in practice.
