All classes were suspended Tuesday at Western Washington University due to an alleged incident of hate speech targeting students of color.

In a message posted to the university website, President Bruce Shepard said that incidents like this will not be tolerated.

“Yesterday, we observed social media being used for hate speech targeted at Western students of color. I need to be VERY clear here: we are not talking the merely insulting, rude, offensive commentary that trolls and various other lowlifes seem free to spew, willy nilly, although there has been plenty of that, too. No, this was hate speech,” Shepard wrote. “These are likely crimes in my view (and in the view of those in the criminal justice system we immediately involved). I cannot go into the details of an ongoing law enforcement investigation. Other than to assure you that this investigation is the highest priority of our campus law enforcement colleagues.”
