2:17 PM: Thanks to Leeann for the tip – low-bridge commuters and others driving in the Harbor Island vicinity might need this heads-up: Protesters say they’ll be staging at the Spokane Street Fishing Pier, east of the low bridge, at 4 pm today. They are protesting an arriving ship operated by an Israel-based company, the Zim Chicago (which is off Manchester as of this writing, per MarineTraffic.com), in opposition to Israel’s actions in the Gaza conflict. A similar protest is reported to have drawn more than 100 participants Saturday in Tacoma. The Port of Seattle’s schedule says Zim Chicago is coming in at Terminal 18.
6:03 PM: Yes, that’s why there’s a TV helicopter over the north end of West Seattle.
ADDED: One protester was arrested, per multiple reports (including the protest group itself).
