This is throat clearing. He very specifically says the refugees are telling the Thai and US interviewers what they want to hear (e.g. lying). He says elsewhere in the article that reports of local party leaders executing people displaced from cities are unfounded. He bends over backwards in several places to discount refugee accounts.

I'd also point out that when the killing fields were discovered, he refused to acknowledge that the early reports from refugees were correct. So he never took them seriously. Why carry water for this piece of shit? He also denied that Serbs were carrying out massacres in the Balkans. His whole thing has always been covering for the crimes of any anti-Western scumbag.

Thanks for proving my point.
