> Both the data and my lived experiences indicate a correlation between more extreme behavior among protestors and more arrests.

I think there's a false attribution of 'extreme behavior' with 'protestors' primarily. feel there are a significant number of people who took advantage of the protests to loot and burn and generally cause chaos. It's worth noting that Seattle and Portland, are primarily Caucasian (67% taken from OPCD), (77% taken from US Census Data) respectively. I think the looting can be more attributed to a general anarchy/countercultural movement in the PNW as opposed to protestors regarding BLM. It's definitely something that is more complex and requires more research than an off-the-cuff comment could generate.
