The closest analogy I could think of was the English soccer hooliganism from 20 years ago. Those guys would get liquored up and cause all sorts of mayhem at whichever soccer matches they chose to attend.
I then Googled "white people rioting," and stumbled across this article, by Becca Stanek, who listed several more recent examples of white mobs committing vandalism. She had this to say (in reference to the Ferguson riots):
Many labeled the protesters savages, animals, hoodlums and thugs…..But the thing is, riots happen all the time, and often over significantly less terrible events — and we talk about them very differently when those involved are white.
She has a point: when white college kids go on a rampage because of the outcome of a sporting event, they are rarely characterized as thugs or savages.
But Stanek also seems to miss a crucial qualitative difference. When the white students at the University of Kentucky, for instance, "rioted" last month after their team lost in the Final Four, the nature of their behavior was completely different. There was no widespread smashing of store windows or looting, no one hurled bricks and rocks at the police, and cars weren't set on fire.
As Lexington police spokesperson Sherelle Roberts said afterward, although 31 were arrested, police were “thankful no one was seriously injured and that there was no major destruction of property.”
Here are some pictures from the Kentucky "riot":
For Stanek to equate Ferguson with a large, unruly crowd of drunken college students is disingenuous at best.
This isn't to say that whites aren't capable of more destructive behavior: those English soccer hooligans were famous for their boozy brawls.
But here's the most telling difference between white mobs and black ones: when large groups of whites misbehave, there's almost always liquor involved. Sober white people simply don't riot, at least not these days. (They wage war, but that's another thing entirely.)
When blacks riot in Ferguson, or Baltimore, or elsewhere, alcohol is generally not a factor. Black rioters don't need Dutch courage.
Whether this is a good or bad thing I'll leave up to you.
