I visited Portland a month ago. There are security guards at each pharmacy and supermarket. I got screamed at by a violent/homeless person because I walked on her block. Some streets - and we are talking downtown/center - I was just afraid or disgusted to walk on. So, yes, Portland is a dump that needs to get cleaned up.
Doubly doubtful for the following reason: these people need the problems to exist, so that they can write their narrative around them, and offer their "solutions" for them. Same as how cults target vulnerable people.
