The protest in Portland was pretty large, I'd estimate 10,000-15,000. The overwheming majority were there to gather peacefully. Lack of discipline allowed in some creeps in to what should have been a good thing.
She was on-topic and a helpful image.
They were on-topic but a harmful image.
She was off-topic and deeply offensive.
Somebody was very smart, though. They told supporters to wear white as color of unity. I'm not sure if this was done to deliberately marginalize the black block, but it sure made it easier for the police...
This guy shouting to the police that they were traitors was not doing the immigration rights people any favors.
Other folks were clearly using the demonstration for their own purposes, note the tissue thin attachment to the topic and the offensive fellow traveller from above.
The Wobblies attended and dreamed that someday they could get this good a turnout on their own, or maybe they thought they did...
I caught myself getting angry at the black block twit trying to incite the police, and so I left before I started a problem. About 20 minutes later I saw a riot team leave the reserve area at the Rose Quarter and start heading downtown, so maybe somebody else abandoned restraint. I leave you with this study in contrasts on May Day.
