Talk to the locals
The motodup driver I used regularly was a great source of useful information about Cambodia. I took one long trip up the Mekong to visit an island and while we were waiting for a ferry we had a really interesting talk about what happened to his family under Pol Pot - his father and 3 brothers were killed leaving him with his mother and sister. He doesn't know how he survived because his father was a policeman. We also talked about how he was working to educate himself so he could go to university and get on. However one to note is that the person you are talking to is old enough to have actually suffered as they say. Remember that the Pol Pot regime fell in in 1979 so if he's only 20 and he says his father was killed by Pol Pot - there's a problem with the arithmetic somewhere
