I tried to read through it, it was very long so I glanced through it. But the reports of Amanda's interrogation does not sound like these cases, IMO. First of all, she was already at the police station willingly. Secondly, I don't think the prosecutor or questioners were yelling at her with "red faces" or yelling very loudly and angry, like it said the detectives were doing in a couple of the above cases. She was not verbally or physically abused by the questioners. In fact, the translator said one investigator went out of his way to be kind to her, brought her drinks, etc.. They were just asking her questions in a calm manner.
I didn't get the sense of any psychological manipulation being done on her, like in the case of the mother accused of killing her child. I don't think she was asked things like "have you ever had thoughts of killing anyone?"...."do you ever fantasize about killing people"...."have you ever hurt an animal?' or any questions like that which would maker her unsure of her own sanity.
I don't believe her interrogation were like any of the cases in the link. Also, as I said in another post, one can probably use Google and find just about anything to support a claim nowadays, doesn't mean that I should change my standards of "reasonable person' or what a "reasonable person" would have done in THIS situation.
