50 protesters gathered last night in San Francisco’s Dolores Park for what was billed as “The Strike Starts Early Street Party.” Party? We think they spelled “violent riot” wrong.

They paint-bombed and broke some of the windows at Mission Police Station, according to officer Daza. By then a group of about 50 had moved to other restaurants north of Valencia Street.

Armed with crowbars, bats and other metal objects, a group of protesters smashed businesses windows in a five block stretch of Valencia Street, from 18th Street to Duboce Avenue.

The bar manager at Locanda, Gabriel Lowe remembers hearing three loud bangs, when he looked out the window he saw a protester throwing paint sacks at the storefront. Several witnesses said they saw a protester trying to break the windows with the valet parking sign that’s in front of the restaurant.

The “street partiers” also smashed windshields, slashed tires, and hit one man with a crowbar. Police received 500 reports of damage.

Luckily, the Occupy San Francisco protesters remain steadfastly committed to non-violence:

Non-violence like this, “Pete_TheKiller”?

An eyewitness describes the scene:

But not everyone thinks it was a big deal.

Many Occupiers tried to distance themselves from the mayhem, which appeared to be dominated by protesters wearing Black Bloc masks:

But Black Bloc isn’t accepting the blame either:

So if it wasn’t Occupy or Black Bloc, who were the rioters? Must be … agent provocateurs!

Or maybe misguided protesters trashing the wrong kind of property:

Occupiers claim the police kept their distance:

We’re wondering, Occupiers, any plans for keeping these protests from erupting into the violence we’ve come to expect?

https://twitter.com/#!/MikeQtips/status/197284885893885952

Nah, no plans for that. That would be unnecessary:
