By most accounts, the celebratory parade to honor the Golden State Warriors’ NBA Championship win in San Francisco last Monday was a successful community event — though not necessarily “peaceful,” unless you count thousands of people dancing, partying and cheering as placid.

But the event was not without its incidents, most of which happened after the parade, according to the San Francisco Fire Department, which assisted with medical emergencies.

The following day, SF Police substation in the Mission tweeted out that a “violent riot” had occurred on lower 24th Street following the festivities and that 17 officers were injured.

The San Francisco Police Officers Association (SFPOA) doubled down on Twitter on Wednesday, releasing a statement calling the alleged rioters “pathetic criminals hell-bent on destroying property” and saying that officers were “targeted and attacked” while doing crowd control during the event. The union called for the “most forceful prosecution” for perpetrators.

However, the San Francisco District Attorney’s Office says that no cases have been brought before them for review regarding fan violence.

“SFPD has not presented us with any cases involving ‘riots’ or violence against police officers,” said Rachel Marshall, communications director for the DA. “We do not know if the POA’s allegations are factual; if so, the SFPD once again appears to have failed to make any arrests.”

San Francisco Fire Department spokesperson Lt. Jonathan Baxter said that most of what he called “civil unrest” happened after the parade.

“Overall, in my opinion, the Warriors fans were amazing,” Baxter said. “A few isolated incidents that Fire is aware of resulted in civil unrest, which in our opinion the SFPD did an amazing job mitigating.”

The San Francisco Police Department did not respond to questions about the union’s tweet nor the reported injury to 17 officers.

Marshall said that not only have no cases against parade-goers come to the DA’s office, but the opposite is true.

“By contrast, we have received requests to investigate alleged misconduct by police officers for using excessive force during the Warriors celebrations,” said Marshall, adding that the office cannot comment further, as it involves ongoing investigations.

SFPOA President Tracy McCray wrote in Wednesday’s tweeted statement that officers had “dangerous explosives” thrown at them and that people purposely tried to maim and injure them.

“Our officers are on the streets, risking their health and lives, to keep everyone safe,” wrote McRay. “To have seventeen injured in one night is inexcusable. True fans can have a spirited celebration and do so with dignity and class.”
