The protest comes the same day that Mayor Mike McGinn sat down with well-known civil rights attorney Connie Rice.
The protesters are concerned about accountability and transparency when it comes to issues with police. And the conversation started Saturday morning at a meeting with city leaders and Rice.
"Be very clear. You have some changing to do," Rice told city officials.
She has spent her career working on police reform. And Saturday was no different.
"Once you get done fighting, you realize that if safety is the first of all civil rights, you have to have the police with you," she says. "You can't fight the police."
Nearly one year after a Department of Justice review found Seattle police were too quick to resort to use of force, Rice attended a forum with the city's mayor - to provide her insight on the issues within the deparment.
"You are going to have to learn what cops do," she says. "You are going to have to respect what they do."
During the discussion, many questions were raised about a recent dashcam incident. Police say the man in the video - Leo Etherly- was driving a van spotted after a hit and run.
Officers say when they tried to question him, he resisted - and spit on them.
But protesters say the video is just another example of on-going issues within Seattle's force. The mayor says changes have been made - and continue to be made.
"This city will hold itself accountable for the actions of all its officers, and we have done that and will do that moving forward," says McGinn.
The city is also planning to form a community police commission. It will include various members of the community, and they will address many of the concerns raised Saturday.
