I snapped this shot during a 6,000 person riot in São Paulo back in March, 2007 when President Bush arrived in the city. The photo was published in The Arkansas Traveler newspaper in March, 2007 on the front page. That same year it won a first place award for news photo at Arkansas College Media Association at the the Clinton Presidential Center. A PDF of the front page with the image I took can be found here.
More of my footage of this riot can be found in the following videos:
