Feds are out in force now after a fire on the facade of the building

They have pushed protesters away from the courthouse, now adjusting their position

The crowd is bringing in barriers

Some in the crowd are calling it a "pig pen"

They are prying more of the facade away, with dramatic drumming as a soundtrack in the background

The feds are back

Running into the park

Getting into formation

Now a standoff on Main Street

"This is not a riot... it's a revolution"

The feds declare an unlawful assembly on the streets of Portland.

Another volley of tear gas

Chasing through the park

After the feds cleared the crowds from the park, they went rummaging through the Riot Ribs food area. Organizers say they threw food on the ground.

The battle with the feds is dying down for the night, but some of the remaining protesters are fighting each other.

"Stop the infighting," someone yells.

I'm headed out. Time to write.
