I disagree. I think that every time investigators are sitting in a room with a witness or suspect, their sole objective is to coerce the truth from that witness or suspect....
BBM: Yeah, and unicorns eat rainbows. If investigators are "coercing" anything, then it is whatever they already believe--which may or may not be the truth. But this is the bottom line for you and others, isn't it? It's just too frightening to contemplate what actually goes on in police interrogation rooms, because it means that any one of us might be wrongfully accused.
I suspect that guilty people probably come up with some whoppers in the first couple of hours of questioning, perhaps with a grain of truth. Amanda's first whopper was that she had a late dinner and watched a movie on the night of the murder. That got her out of the questioning session until police checked the facts (computer and Dr Sollecito evidence). I'm sure she later added the lie that she and Raffaele slept until 10 AM. That turned out to be a lie - sort of, although they may not have gone to sleep until 6 AM. Always a grain of truth with a whopper of a lie.
These are your ideas of "whoppers"? I don't think you're clear on the meaning of that term. And by the Night of a Thousand Statements, how many days had passed? And yet AK got the time of her dinner wrong! Unfathomable!
It is true that by the time Amanda voluntarily went to the police station and offered a statement about Patrick, she had been questioned before ... but what is almost always overlooked is the fact that during each of those interviews, she lied. Amanda's grain of truth on the night she accused Patrick was that she was there, the whopper was that Patrick was a murderer.
You've discovered transcripts of AK's various interviews? Swell! Point us all to them. You do get the definition of "whopper" right when you mention PL, but of course we all know who brought him into the mix.
Those "grains of truth" you identify are just you picking and choosing what you want to believe from AK's testimony, much as the prosecution did. This is a common LE tactic--particularly with coerced statements--but I've never understood the logic myself: "Oh, yeah, the defendant is a liar, EXCEPT magically when it helps my case. THEN she tells the truth!"
Coercion with bopping on the head is different, but out of supposedly 10 officers in the room at the time, not one of them saw any bopping on the head at the 2 hour mark ... or at any time. There was no bopping on the head before any of the lies except the last ... the one where she screwed herself through ignorance about the law.
I don't know whether AK was hit or not. But it's not a secret that police officers will lie to back each other's accounts, especially when official misconduct is alleged. Again, apparently this is a fact too frightening for you to contemplate.
Police lying to a suspect during questioning is perfectly acceptable pretty much everywhere, but lying under oath? Are you suggesting that it is quite acceptable for Italian police and investigators to lie under oath?
I think that was a misstatement, since we were discussing lying in interrogations, not under oath. Not that police never lie under oath; we know that ILE did so in the AK trial.
But that gives me a great idea! If any of us is ever questioned by police and asked to swear to tell the truth, we should reply, "I will if you will."
