The movement has swept across the country in recent weeks and has been picking up steam in several Indiana cities.

Protesters have been lambasting corporate greed and government policies, but there appears to be little in the way of a cohesive message.

Social movement experts said the grassroots groups will need to make some changes within themselves if they ever hope to inspire change among policy makers, 6News' Chance Walser reported.

"Is someone going to rise up and become the leader of this movement?" Indiana University Purdue University-Indianapolis professor Lynn Pike asked her sociology class.

Students said they aren't sure what the series of protests might accomplish.

"There's some people who have really defined problems and interests, and then there's people who are just like hippies just running around like, 'I'm tired of it,'" said one student.

In Indiana, there have been protests in several cities, including Indianapolis and Bloomington, where protesters are in tents.

"I'm not really sure what is exactly going on. I don't think anybody is," said one protester, who didn't share his name.

Others are working to craft a message, but they're having difficulty reaching a concensus.

"We're still working on getting a common goal that we can give," said protester Tyler Yount. "I'm tired of corporations controlling the process. I want to give power back to the people."

Indiana University professor Fabio Rojas, who has made a career out of studying social movements, said the movement will need to clarify its focus to survive.

"That's going to be an obstacle in the long term," Rojas said. "You're going to see some more protests for another month or another year, possibly, but they're going to have their impact when they decide that they are going to be a little bit more professional, that they are going to figure out how to get themselves into the policy and lawmaking process."

The movement is spreading to other Indiana cities, with a march set for Muncie this weekend.
