According to a statement released by the university's dean of students, Paul Shang:
The University of Oregon Police Department is investigating an incident, captured on video, in which a passing vehicle was the target of snowballs thrown by young people in an area on the UO campus. Police hope to determine the identities of those who were throwing snowballs, whether they are UO students and whether their actions constitute a criminal act.
The University of Oregon takes the conduct of its students seriously. Consequences are clear for those whose actions reflect poorly upon the university or violate its standards for student behavior. However, until the facts of the snowball-throwing incident are sorted out, it would be premature to speculate about any potential outcomes in this case.
Oregon Offensive Lineman, Andre Yruretagoyena, took to Twitter to express his disgust with his teammates' actions
Embarrassed by the video I just watched. That's not all of us, sending the sincerest apologies.
