More than 600 people of all ages and races marched Saturday from Garfield High School to the Seattle Police Department headquarters downtown to protest police brutality.
The protesters chanted “same story every time, being black is not a crime,” and “no justice, no peace, no racist beliefs” as they march down the hill.
“As a people, we need to stand up and voice our opinions peacefully. No more war, shooting and killing,” organizes wrote on Facebook. “As young people, we cannot stay silent. We need to get loud and be heard.”
Organizers from Garfield High School and the University of Washington’s black student unions met with Seattle Police before the protest started at noon to ensure it would remain peaceful.
The main protest broke about 3:30 p.m. after a rally at Seattle police headquarters at 5th Avenue and Cherry Street.
