Years with an HN recommendation, 2007–2026

HN commenters use it to show that behavior in interrogations is not a reliable sign of guilt and that police lie to innocent people.

A compilation of police interrogations of innocent suspects who behave in very different ways yet are treated as guilty. It illustrates how interrogation tactics and detectives' assumptions can distort the truth.

“It shows two example interrogations of innocent suspects, each displaying completely different behaviour.” (HN, 2021)

on HN thread How can you tell if someone is lying?
This video is relevant: [this video] It's about interrogation, and the common notion that a guilt can be inferred by the suspect's behaviour. It shows two example interrogations of innocent suspects, each displaying completely different behaviour.
Innocent suspects behave differently in interrogations, showing guilt cannot be inferred.

>It's not really about leverage or power. It's more of a strategic setting where the winning move is either to be 100% truthful (if you're innocent - and even JCS acknowledges this!) or not to play. It seems to be the opposite. This JCS video shows 100% non-guilty people being 100% truthful, and their truthful statements are regularly seen as further evidence of their criminality: [this video] Whether you're completely guilty, partly guilty, or completely non-guilty, the safest thing to do is to say absolutely nothing. >It can however be strategically beneficial to the innocent if done lightly and with proper foreknowledge, because if you can precisely and vigorously call the interrogator's BS about what evidence they do or do not have, this sets you apart from someone who's just making stuff up as they go along and cannot possibly be able to do this. I really don't think this is true at all. Again, I think it's the complete opposite. I think it's total BS that trying to call BS about evidence would somehow help you in any way. Someone making stuff up as they go along can definitely very possibly do what you say, especially if they're relatively intelligent. And someone being 100% truthful may not be able to do this, if they think the police can't lie, and/or if they know nothing about forensics. In any of the four scenarios (guilty and try to call them out; not guilty and try to call them out; guilty and don't try to call them out; not guilty and don't try to call them out), you'
Innocent people's truthful statements treated as evidence of guilt.

If you're interested there are plenty of interrogation videos on yt, some by the FBI are particularly interesting. Sometimes they have a pretty good case but getting a confession tremendously speed up the process so they lie to get confessions. They also can lie to trigger responses and see how the suspect react, guilty people seem to react in way different ways than innocent ones. It's obviously not an exact science, even though it's heavily studied and has some psychology compounds, but it worked and put countless number of guilty people behind the bars A source I like is: [link] This timestamped video is an example of a cop lying (to innocent people): [this video]
