New York ? A day after police broke up a rally at Manhattan’s Zuccotti Park and arrested dozens, Occupy Wall Street protesters said Sunday that their movement for economic justice would pick up momentum with the spring.

Activists listed issues including student debt, the environment and the November elections as priorities going forward. But some observers who watched workers hose down the now-barricaded park that was Occupy’s home wondered whether a movement so diffuse could accomplish anything.

“I’m really grateful to be part of a generation that wants change, ’cause we should all want change,” said Jennifer Campbell, a graduate student in documentary filmmaking at Hofstra University. “But I’m not sure what that change is, or if they know what that change is.”

The crackdown at Zuccotti happened late Saturday after hundreds of activists had gathered to mark the sixth-month birthday of the movement.

Police said 73 people were detained. It was unclear how many were still in custody Sunday.

As cleaning crews used hoses to erase all signs of the clash on Sunday, Occupy activists offered differing perspectives on where the movement is headed.

“We’re going to keep going,” said Christopher Guerra, who has spent many nights at Zuccotti since the movement started last Sept. 17. He added, “It’s going to get interesting during the election cycle. We’re going to be more of a presence in the political world. I know we have a couple of people running for office.”
