Interestingly the protest took place on Main St. (and Mt. Diablo Blvd.) so the sign is pretty accurate.
By 6:30 pm when these photos were taken, most of the protesters had already left, with only about 10 remaining on the four corners. According to one of the protesters, they believe there were less protesters today because the location kept changing (last week it was at the Walnut Creek Bart station), and there will be another protest this Saturday. She had positive things to say about the Walnut Creek police; quite different from what’s happening in nearby Oakland.
