Not exactly a relevant comparison, since the riot last week did not happen in Portland or Seattle.
A more apt comparison would be the BLM protests in DC over the summer. Which were
significantly less white. Same place, same organizations in charge. VERY different response. Now, you could argue that the backlash over the summer protests perhaps made law enforcement a bit wary of over-responding. But when you've got the FBI sending out
warnings of potential violence, you'd think that they'd have had more personnel at least in place and ready to go, even if they weren't immediately visible.
