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.
