No. In order to lie, they must tell about some fact. Assert "clear and convincing evidence" seems to me too generic, it seems more like telling an assessment rather than telling a fact.
And if the you say "I have evidence" in generic terms, I would (anybody would) respond by asking "what evidence?", "why do you think it is evidence?". So it boils down to giving some fact.
Goon squad:
'We have hard evidence you were at the scene, who are you protecting? Tell us now or you'll be imprisoned for thirty years!'
Ragazza:
'I...uh...what hard evidence? I'm...not protecting anyone, please believe me!'
Goon Squad:
'We're asking the questions! You need to answer them or you'll never see your mother again! Who did you meet that night, tell us!'
Ragazza:
'I didn't meet anyone! I was home with Raffaele, why won't you believe me!?!? What evidence could you have?'
Goon Squad:
'You'll find out at your trial! Raffaele says you went out and told him to lie! We have all we need to put you in prison right now! If you tell us it will go easier for you!'
Ragazza: 'Raffaele? Why would--'
Goon Squad:
'No Questions, just answers! Stop lying! Tell us the truth! We know you met someone that night, tell us!'
Ragazza 'I don't know what you mean! Maybe....shouldn't I have a lawyer?'
Goon Squad: 'It will only get worse for you! We know you were there! We know you are lying! You are a dirty filthy liar and you will tell us the truth or we will arrest you!'
Then maybe someone comes along, things settle down, and they console her a little, regale her with their solemn duty to find Meredith, guilt-trip her a little for not helping etc. At any rate
they're running the show, they're
not taking questions! It's not a lecture hall or a discussion. They want answers and they're going to get them, just about anyway they can. They have to be pretty damn sure she's involved with Patrick to ever send those seven cars sirens screaming to Patrick to haul him out of his house off of those worthless statements, so they simply go too far to get what they want.
Machiavelli, the point here is that one cannot go from those vague and confused statements (with
nothing else as they'd claim) to their actions later culminating in the victory lap and 'case closed.' Those statements don't produce that event, there's a confounding factor that explains both those statements and that bizzarre triumphalist behavior, that is their strong suspicions of both Amanda and Patrick going in which produced both those statements and their willingness to accept them as anything but ridiculous.
Anyway, there is no automatism like: police lie = explanation for false accusation. A lie or misconduct by the police does not imply a motive, a justification or even less necessity to release false testimony and false accusation. Thus it won't work, itself, as an explanation for Amanda's behaviour.
It's a tactic, Machiavelli, it works really well at getting criminals to confess because they figure they're 'caught' anyway, they might as well get it over with. Since if the interrogator says something too specific about what 'evidence' they have it might give it away, they cut those questions off and return to the offensive. The parts Amanda is going through a translator for, the police-beholden translator might not even translate that question, or do so more than once as they'll know how the game is played as well.
Machiavelli, what is your explanation for those statements looking like sheer lunacy and the cops being satisfied with that?
