Funny you'd link to that. I don't see any picture there of the asshat who called the cops on the student.
Browsing briefly through the CNN website I see a number of article where the suspect doesn't have a photo shown despite being white rather contradicting Lewk's theory. Here's one from today, what's CNN's agenda for not showing the racists photo here? He's already been arrested and charged but still no photo.
