OAKLAND (AP) — The city that became the national epicenter for the Occupy movement braced Thursday for a rally and march marking the day one year ago when protesters were removed from an encampment on a City Hall lawn, sparking the first of many clashes with police. Rally organizers have vowed to take back the plaza and set up tents again, while encouraging others to arm themselves with unspecified "tools of violence." Some Occupy Oakland members publicly denounced those tactics and urged the group to get back to its main issues.
