The recent genocidal Khmer Rouge era resulted in the deaths of millions of Cambodians in the 1970s, while displacing many who ended up in refugee camps in Thailand.
The upheavals resulting from the aftermath of the Khmer Rouge regime are still felt today, both psychologically and economically.
I spent three fairly intense months in Cambodia running around the country with my camera, pen and paper, interviewing survivors of the genocidal maniacs known as the Khmer Rouge.
It is my last day in Cambodia. I am sitting in a crowded courtroom staring through bulletproof glass at the man who presided over the killing and torturing of more than 16,000 people in Tuol Sleng prison.
