Many students at Northwestern University are upset over the blackface Halloween costumes of some white students, NBC Chicago  reported. Morton O. Schapiro, Northwestern's president, sent an e-mail to students saying: “While I fully support the principles of free expression, at the same time I am deeply disappointed to see any example of insensitivity that demeans a segment of our community." A forum on the incident Thursday night attracted many students. The Daily Northwestern  ran a live blog on the forum, attracting many comments. Northwestern is far from the first campus at which blackface or racially stereotyped Halloween costumes have created racial tensions.
