REMOVES REFERENCE TO OCCUPY WALL STREET PROTESTOR - Robert Neuwirth types on an old-fashioned typewriter as part of an art project in Zuccotti Park before a march to celebrate the protest's sixth month, Saturday, March 17, 2012, in New York. With the city's attention focused on the huge St. Patrick's Day Parade many blocks uptown, the Occupy rally at Zuccotti Park on Saturday drew a far smaller crowd than the demonstrations seen in the city when the movement was at its peak in the fall. A couple hundred people attended.

NEW YORK — Occupy Wall Street protesters are anticipating their movement for economic justice will begin picking up momentum this spring.

Activists list issues including student debt, the environment and the November elections as priorities going forward.

But on Sunday, a day after police broke up a rally at Manhattan's Zuccotti Park and arrested dozens, some observers wondered whether a movement so diffuse could accomplish anything.

Harlem resident Kanene Holder says "We cannot homogenize this movement into one streamlined vision."

Meanwhile, police spokesman Paul Browne confirmed police are seeking a subpoena to identify an apparent Occupy protester who they say tweeted a threat to kill police officers.
