1:48 PM: Via both SPD and a campus source, we’re told some West Seattle High School students have joined the walkout to show opposition to the Ferguson, Missouri, grand-jury decision. Some other schools in the city including Garfield and Roosevelt had hundreds walk out.
2:20 PM: We just missed the walkout but got some reader video we’ll add when back at HQ. Police we talked with just off-campus estimated about 75 participants and say it unfolded peacefully.
2:44 PM: Added the aforementioned video atop this story (recorded by a reader from the top parking deck at Admiral Safeway, looking west), plus our photo of the police who were still at California/Stevens when we arrived. Another texter said some had walked out at Chief Sealth International High School earlier today, but we have not confirmed that. The district’s message about the walkouts is on the SPS home page.
