Racial Discrimination Incidents in Syracuse University

Sometimes doing nothing about it is even worse than explicitly express racial discrimination. This article from Wall Street Journal reported several incidents happened in Syracuse University in New York, where there were no crime happening, but the threats by white supremacists were frightening to the African American and Asian students studying there. The most shocking fact was the reactions of school administration. They are not enthusiastic on finding who did this and stop these things happening again, but only tell their students to calm down. Does that really help solving the problem?
