The event comes on the eve of the one-year anniversary of the death of Alan Blueford, who was 18 when he died.
The plan was for marchers to meet at 98th and Bancroft avenues and walk to 9200 Birch St., the site where Blueford was killed May 6, 2012.
In early October, prosecutors decided the officer who shot Blueford would not face criminal charges as the Alameda County District Attorney's Office determined the shooting was justified.
In a report, District Attorney Nancy O'Malley said she agreed with the conclusions of a senior deputy district attorney who investigated the shooting and found that Officer Miguel Masso had an "actual and reasonable belief that he or others in the area were about to be shot by Mr. Blueford."
The shooting of Blueford has caused major disruptions at City Hall as family members and supporters have accused the Police Department of covering up for Masso and have claimed that the shooting death was unjustified.
The group has held several rallies since Blueford was killed, including a raucous gathering at a City Council meeting in September that disrupted proceedings and led council President Larry Reid to shut down the meeting.
The family has also filed a federal wrongful death lawsuit against the city.
John Burris, the family's attorney, has said he was not surprised by the report's findings and said it has no bearing on the federal wrongful death lawsuit filed against the city. Burris continues to maintain that Blueford did not point his gun at Masso.
But the district attorney's report found that Masso did nothing wrong in the early morning hours of May 6 when he chased Blueford on foot and eventually shot him three times.
