There are several first-person account books written by Cambodians who lived through the Khmer Rouge regime. They are very disturbing, but essential history and well worth reading. (Two excellent ones are ... Survival in the Killing Fields, and When Broken Glass Floats.)

Anyway, it was nice to read about your adventures in Phnom Penh. I only passed thru it one day, but it appeared to be a fairly civilized place. Your report basically confirms that.
