It's a ritual now: The San Francisco Giants win the World Series, and joyful revelers take to the streets.
And then the revelry turns into something different: drunken crowds, street fires, dangerous fireworks, escalating vandalism and violence.
The disorder first draws a response from the police, who arrive en masse, then a counter-response from the crowd in the streets -- which last night took the form of barrages of bottles that occasionally hit police officers and bystanders alike.
Yes, there were lighter moments before missiles filled the smoky air in the Mission and around AT&T Park. Fans drenched each other in champagne. A sound system at 16th and Valencia streets blasted Queen's "We are the Champions" as fans sang along from atop a nearby bus stop. Good times.
And then came the other stuff -- some of which is recorded below in pictures by KQED intern James Tensuan, who was in the Mission after the game. Police Chief Greg Suhr said Thursday that three police officers were treated and released after being struck by flying bottles.
