Occupiers are tired of being ignored has beens so decided to get rowdy, burning flags, destroying equipment, vandalizing and generally breaking as many laws as they could to get arrested and drum up some attention.

Dozens of police maintained a late-night guard around City Hall following daylong protests that resulted in 300 arrests. Occupy Oakland demonstrators broke into the historic building and burned a U.S. flag, as officers earlier fired tear gas to disperse people throwing rocks and tearing down fencing at a convention center.

Quan said that at one point, many protesters forced their way into City Hall, where they burned flags, broke an electrical box and damaged several art structures, including a recycled art exhibit created by children.
She blamed the destruction on a small “very radical, violent” splinter group within Occupy Oakland.
“This is not a situation where we had a 1,000 peaceful people and a few violent people. If you look at what’s happening today in terms of destructing property, throwing at and charging the police, it’s almost like they are begging for attention and hoping that the police will make an error.”
Since Barack Obama incited the original Occupy movement and Democratic politicians embraced, encouraged and supported them and San Fran Nan Pelosi herself "blessed" them... I say give them all the attention they want to remind voters of the divisive class open warfare Barack Obama has pushed for in this country.
