This is not the first post that I've read that criticizes the Italian police for telling lies to Knox. I have the impression that some are of the opinion that this is unethical, if not illegal, and unusual. And some folks seem to think that it justifies Knox’ lying. In point of fact, presenting suspects with false information is a common police technique. There are abundant reported cases holding that confessions given in response to trickery do not violate due process rights, or any other constitutional rights.Solange305,
From page 151 in Murder in Italy, “Alternatively, Amanda would say she was not “treated like a person” until after she’d signed on the dotted line [at 5:45]. No food, no water, no bathroom breaks or naps.” So what Steve Moore said is disputed, but it is not agreed upon to be untrue.
The more general problem with your comment is that you don’t seem to be applying the same standard to ILE. We have documented their misstatements here for 11 months. Some are doubtless honest errors, but some look like lies (not disclosing that the TMB test was negative, for instance). We have also documented examples of their mistakes; the hard drives being the most recent example to resurface in this thread. Why does their credibility not suffer among the pro-guilt commenters here and elsewhere?
There are rules that apply to the sort of thing. Generally speaking if the false statement is "intrinsic" to the crime being investigated it is permissible. For example, it is permissible to falsely state that the suspect's fingerprints or DNA was found at the crime scene, that an eyewitness has identified the suspect, etc.
False statements that are "extrinsic" to the crime are out of bounds because they are likely to be coercive and produce false confessions. For example, telling a suspect that confessing will lead to a reduced sentence, or telling a female suspect that if she does not confess, she will lose custody of her children while she will be able to keep them if she confesses, are examples.
The police can still be credible because they generally don't try to cover up or lie about their deceptions after the interrogations, and are usually the source of the information that such tactics were used. And when they testify, they are under oath.
