Arizona's dream for a national championship turned into a nightmare last night.
Rubber bullets, fires and broken windows overshadowed the supportive crowd of Wildcat fans on Fourth Avenue when nearly 500 police officers - outfitted with bullet-proof shields and nightsticks - broke up rioting and looting.
More than 2,000 Arizona fans - who watched the UA men's basketball game in bars along North Fourth Avenue - started out cheerful and spirited, even after UA's 82-72 loss to Duke University.
But soon the spirited atmosphere went awry when fans began to tear down street signs and assault one another.
Collective disappointment evolved into an excuse to vandalize property and loot Fourth Avenue businesses.
Nearly two hours after the game, the chaos began to erupt.
