The only surprising part about this story is that it has taken this long for the local mentally unstable unhoused population to start getting aggressive and for it to become commonplace enough that people are posting about it. A couple of years prepandemic we did a trip all over the PNW, and were floored to see how much Seattle and Portland have decayed. The homeless situation is BAD over there, in large part fueled by drug addiction, and a lot of those people would be panhandling while high or tweaking and they were REALLY aggressive and some would spit at people and such. It really soured my prior impressions of both cities, which I had really enjoyed years before.
