There are other factors (relating to points made in the post) to suggest the protests in UK and EU may carry less risk comparatively. Police tactics at protests in different countries may be a relevant consideration—e.g. the heavy use of tear gas in the US (bad for spreading covid, as larks notes) isn’t happening in the UK. R0 also a relevant consideration—likely much lower in many european countries now than in many parts of the US.
Is the R0 lower in Europe? The 3 day average deaths per million is similar in the US, UK, Sweden, and (eg) Italy. Fatal shootings by police officers of citizens per capita are about 170x lower in the UK than the US. Imprisonment as % of the population is about 20x higher in US than US. Prison conditions seem far worse in the US than UK
I would expect deaths to be on a lag (it takes a few weeks on average for people to get sick enough to die). At a quick glance, France, Spain, Italy and Germany are reporting an average of well under 1k new cases a day for the last 7 days, compared to 19-25K/day for the US (obviously necessary to correct for the USA having a 5-6x larger population than these countries).
Edit: this site estimates R0 as being 1.02 in the US overall, and <1 in all western and northern European countries (although >1 in several eastern european countries)
