This story is amusing... except for what it says about the mindset of the speech/sensitivity police on the modern university campus.

A janitor whom a university official had accused of racial harassment for reading a historical book about the Ku Klux Klan on his break has gotten an apology -- months later -- from the school.

Charles Bantz, chancellor at Indiana University-Purdue University Indianapolis, apologized to Keith John Sampson in a letter dated Friday, saying the school is committed to free expression.

''I can candidly say that we regret this situation took place,'' Bantz wrote.

Sampson's troubles began last year when a co-worker complained after seeing him reading a book titled ''Notre Dame vs. the Klan: How the Fighting Irish Defeated the Ku Klux Klan.''

The book's cover features white-robed Klansmen and burning crosses against a backdrop of Notre Dame's campus. It recounts a 1924 riot between Notre Dame students and the Klan in which the students from the Catholic university prevailed.

Sampson, a 58-year-old white janitor and student majoring in communication studies, said he tried to explain that the book was a historical account.

''I have an interest in American history,'' Sampson said. ''I was trying to educate myself.''

But Sampson says his union official likened the book to bringing pornography to work, and the school's affirmative action officer in November told Sampson his conduct constituted racial harassment.

''You used extremely poor judgment by insisting on openly reading the book related to a historically and racially abhorrent subject in the presence of your black co-workers,'' Lillian Charleston wrote in a letter to Sampson.
