The North Carolina NAACP demanded changes from N.C. State University on Wednesday, one week after threats were found on campus against President-Elect Barack Obama.

NAACP President Rev. William Barber and other organization leaders met behind closed doors Wednesday morning with N.C. State Chancellor James Oblinger.

The college said the four students were responsible for painting threats to Obama on the school's Free Expression Tunnel on campus.

The students have been identified but their names were not released.

The U.S. Secret Service and Wake County District Attorney's Office investigated, but determined there were no immediate threats and the writing was on a place that encourages free speech.

"We don't have free speech for making race-based threats of death," said NAACP Attorney Alan McSurely.

McSurely called the incident a crime and questioned why the students weren't criminally charged.

The NAACP is demanding the school expel the students and require all freshmen students to take diversity training.

Following the meeting, Oblinger did not answer questions but said the meeting was "very positive."

"I think both sides have a good understanding from each other's perspective and we agreed to move forward," he added.

The NAACP equated the threats to terrorism, and said they were fearful the students responsible posed an actual threat to the campus.

"How do I not know they're the same students that sit beside me in class?" asked student Megan Wallace.

"Being expelled is a little harsh because this is a free expression tunnel, so you're obviously free to express whatever you want," said student Sam Allen.

The NAACP said it gave the university two days to come up with solutions to address their concerns.
