Protesters from Occupy Oakland
Protesters from Occupy Oakland -the local offshoot of Occupy Wall Street- knock down fences to escape from the police after they were surrounded to be detained on a vacant lot in Oakland on January 28, 2012. Police have fired tear gas and arrested more than 100 people as anti-Wall Street protesters tried but failed to take over downtown buildings, including city hall, in Oakland, California.
