OWS Oakland being hands down the most violent Occupy branch in America.

OAKLAND, Calif. — Occupy Oakland activists have set up a new encampment in a park north of downtown, calling it a response to the recent arrests of protesters in New York and the shooting death of an unarmed Florida teenager.

About a dozen people in six tents spent Wednesday night in Mosswood Park at Broadway and West MacArthur Boulevard. They were still there Thursday.

Police visited the group around 9 a.m. but did not ask them to leave, according to protesters.

“This is the start of the spring offensive,” said Melvin Kelley, a member of the group’s Tactical Action Committee. “This is our new encampment until May 1, when we retake” Frank Ogawa Plaza, which the group occupied last year.

Kelley said the activists had pitched tents to show support for Occupy Wall Street protesters who were arrested in New York’s Zuccotti Park last week while commemorating the six-month anniversary of the movement.

They are also protesting the killing of Trayvon Martin, a 17-year-old African American who was shot to death by a white man in a gated community near Orlando, Fla., on Feb. 26. The man, George Zimmerman, says he was defending himself against the unarmed teen and has not been arrested.
