Two separate petitions have been filed against Seattle Mayor Jenny Durkan over the police reaction to the protests surrounding the killing of George Floyd. Petitioners would need over 54,000 signatures to get on the ballot (25% of turnout). Since Washington is a malfeasance standard state, there would need to be a showing of cause that meets the statutory definition. As we've seen, this is a high bar.
One petition is about the police reaction in dispersing protesters. The other claims that the curfew was set too quickly without giving protesters enough time to get away.
