One student quickly approached Horowitz in a doorway during an interview with NewsLink Indiana and attempted to hit him with a cream pie. The pie missed Horowitz and instead hit Gene Burton, the university public safety director and Horowitz' bodyguard for the night.

"There are problems on this campus, quite obviously," Horowitz said. "I was invited here to speak, and before I could even do that, I was physically attacked."

A second student, apparently another protestor, began running away from police. Both were arrested, though police did not release names or charges. The students were two of several protestors on hand.

Horowitz, a noted critic of higher education, went on with his program.

"I'm concerned about the state of academic freedom and academic standards at this university," said Horowitz, who believes certain professors unfairly press opinions on students.

He spoke about fair presentation in the classroom and criticized several departments at Ball State, including sociology, women's studies and the peace studies program, headed by George Wolfe.

Wolfe made the list in one of Horowitz' most recent books, "The Professors: 101 Most Dangerous Academics in Education." Both men are known for disliking the other.

"A professor should be professional in the classroom," he continued. "They can teach about controversial issues, but they shouldn't try to force their students to take their view of a controversial issue."

The author and critic spoke adamantly about the lack of diverse opinions at Ball State. He also singled out university President Jo Ann Gora for disapproving of his presence on campus.

"I don't understand why the president of this university would take a hostile attitude toward the students that ask me to come here, "Horowitz said.

He was invited to campus by student conservative groups.

Horowitz claimed students are missing out on key opportunities at Ball State: "Students pay $13,000 to go to this university, and they deserve a professional education, not a political indoctrination," Horowitz said.
