Here's a cool documentary on Khmer youth and how they got caught up in the street life in America. Once caught up, the American government just started deporting these young men back to Cambodia. These young men explain how life is hard and different in Cambodia.
In my opinion, it was a good documentary. There's like 15 parts to this documentary on youtube, but here's the link to part 1 http://www.youtube.com/watch?v=5x4RCol0pKQ
