A helicopter is hovering over the Hilton Hotel downtown, where Jamie Dimon, head of JPMorgan Chase, is speaking now to a group of businesspeople, financiers, and golfing types. I can't tell whether it's a news helicopter whose passengers are hoping to film scenes of protest, or a private conveyance poised to remove Mr. Dimon from the crowd of unticketed Portlanders outside the hotel awaiting their chance to tell him their views on financial deregulation.
