I can't say I was surprised this week when Philadelphia Eagles fans tore up the city when their team won the Super Bowl.
And I can't say that I was surprised when many people acquiesced the vandalism, window-smashing and car overturning as hijinks and not thuggery.
That's because football is part of Americana - and smashing windows, setting fires and overturning cars is a celebration of that.
But to disrupt traffic, block a bridge, or kneel down to protest racism and police brutality is to illuminate ugly aspects of America; aspects that most Americans don't want to own up to.
So, the game revelers get a pass. Footage of their riotousness isn't examined by law enforcement to catch perpetrators as much as it is analyzed by sociologists and psychologists to learn what makes them behave that way.
Think about it. White rioting is analyzed; black resistance is vilified. The former is approached as something that is explainable; the latter is condemned as something undeserving of an explanation.
That's not surprising. This is America.
