Affirmative action on law review?

The Baltimore Sun has this report on concerns about the all-white law review staff at the Vanderbilt law school, which has prompted one student to say that "[m]aybe grades and writing just aren't the only things to determine who should be on the law review." The article notes that at some law schools, "such as the University of Virginia, have adopted some form of affirmative action - for instance, by having applicants submit a 'diversity statement' on how they would add perspective to the review."
