[Crime Shows] Why do the Genius Detectives stand there explaining to their suspect their entire theory as to why the suspect is guilty?

The police don't need to do that. They can just arrest them. Explanations like that are for court. Furthermore... confessions as evidence are basically worthless hearsay. Why does it seem like every investigation hinges entirely on revealing what happened to the suspect to get their confession?

Without tangible evidence any competent D.A. would tear that case to shreds and the accused may as well have never been arrested.

It's an interrogation tactic. IIRC there's an episode of CSI where through a process of lying about being able to pull fingerprints off a bag of drugs found in a toilet they convince a dealer that they knew he threw them in the toilet. He is so distraught over the thought that he confesses. Unless there's some amazing oversight in evidence a suspects confess is enough. Longer trials and court proceedings really aren't needed with a signed confession and guilty plea. Stroking your own ego by laying out the crime and the attempt to hide in detail based off evidence you've already collected is stupid but could be harmless if the DA is already going to arrest and press charges. The goal is to convince the suspect that they're hopelessly caught and to just confess and give up. A few show even show how bad this is as a tactic when the suspects and their lawyers get evidence thrown out. The defense knows from super genius that the entire case hinged on that and knew just what to work on to get thrown out. If you have an orgy of evidence losing a few pieces isn't terrible however and they tried to shorten the conviction process. It's just when it's a tenuous piece of evidence that it's a terrible idea to tell the suspect how wrong you're understanding of what happened was.

I am confused. How is a confession hearsay?

That is still not the same as hearsay. And not every confession is a result of police abuse. After giving a confession, the defendant still has the chance to speak to a lawyer, plead innocence by extraordinary causes etc. A confession isn't meaningless but it is evidence. It isn't hearsay.

You have the right to remain silent. Anything you say can be used against you in court.

It's literally the second line of the Miranda warning. Police can use anything you say to them as evidence against you in court, as long as it was obtained legally.

It is very different. But if you don't have reliable legal counsel and a DA that's not as ethically or impartially minded you'd be surprised what can happen. People have been convicted for others dreaming they committed a crime and others have convicted simply because the police fudged information and no one double checked. Obtaining a confession under duress requires a lawyer to prove it was falsely obtained or a judge to consider it suspect. If you're sadled with a public defender that's given up on your case, a confession you signed under duress and a police station with no working cameras the day you signed it it's pretty difficult to prove your case.

District attorney. Basically the states/city/county's lawyer. Usually elected publicly. A public defender is a lawyer provided by the court to the defense at no cost. This is for united states courts and I'm not a legal expert so may be wrong with some details.

But confessions are obtained under duress all the time, they're basically worthless, as your example shows.

Have you seen Making a Murderer? One of the guys is seemingly in prison based solely on a confession which some Seventh Circuit judges assert was obtained under duress.

You also seem to be under the impression hearsay is worthless. Inculpatory hearsay is admissible so a confession is evidence regardless, and there are countless other exceptions which allow hearsay evidence.

​

Nothing people say is meaningful because people can say anything really.

Sure people can lie or be mistaken, but you can't disregard all witness testimony based on that, the lawyers need to establish or critique the credibility. Until about 40 years ago with the dawn of DNA testing and CCTV, that's all the evidence there could really be if the criminal wore gloves.

Detectives are allowed to use subterfuge / deceit to obtain a confession. Not classified as under duress.

Almost all evidence is hearsay. The belief that all hearsay is inadmissible is something created in the media.

Things said to a cop, are almost always admissible even before arrest or Miranda warning.

And duress is a higher bar to reach than you think.

Video citation: you may not agree with the topic, but the discussion of the nature and rules of evidence is on point.

Circumstantial is not the lesser form of evidence contrary to common understanding. The movies, and people who don't actually know how to argue and don't actually know the law, have created this mythology that circumstantial evidence is inferior or second class.

It's simply not the case.

One of the problems that are actively encountered during jury trials is of course that the jury has watched too much CSI or other crime scene procedurals. They bring in a bunch of faux expertise and imagine that their understanding of the law matches the laws understanding of the law.

That's part of the reason that lay advice is not the same as proper legal advice, and it's also part of the reason that people admitted before one bar may not be willing to come and about the law in front of another.

Doyalist answer, this is a trope that goes back at least to Sherlock Holmes. It gives the writer a chance to walk the reader/viewer through the evidence without spoiling the suspense during the investigation.

Watsonian answer, not only might it provoke a confession from the accused, but Sherlock enjoys showing off his powers of deduction.

It's either a form of making someone confess (skips an expensive and drawn-out trial), a trick (they know enough about the murder but can't find one piece of crucial evidence so they trick the guy into blabbing), arrogance (Sherlock Holmes and, in particular, Hercule Poirot were always described as having to show off) or just to give the killer a right verbal bollocking.

With the first kind, avoiding a trial, they make it absolutely sure that they have an iron-clad case against the killer and know everything about the murderer's scheme. It's basically a final "Out" for the killer, offering a plea deal where they admit everything and get a reduced/lighter sentence; expect to see someone take this if a life sentence or execution is a possible sentence.

When it's done as a trick, they're basically trying to wind up the killer into admitting more than he should let on. There's a TV show called Endeavour, a prequel series to a late-80's, early 90's UK series called Morse which pulls this off rather well; Morse figured out that the killer, an employee in a munitions factory, was the killer because he got paint on his jacket when he committed the murder of someone found in the factory because >!he was presented to the Queen's sister without it, since he couldn't get changed after he killed the guy!<. Morse proceeds to trick him into admitting where he hid the jacket by having a fellow officer appear with a large evidence bag and make the guy think they've already found it.

Again, sometimes the detective is arrogant and wants to make it clear that he's thoroughly beaten the killer or to boast in front of an audience.

Then there's the instances where the detective confronts the killer and reveals they know everything... and that the killer is a complete waste of skin for having committed such a vile and disgusting act as murdering someone for their own benefit.

A prime example of this kind is the Agatha Christie's Marple adaptation of The Pale Horse. Unlike the original book where Mark Easterbrook is the main character assisted by Ariadne Oliver (a character from the later Poirot tales), Miss Marple is the detective involved in the case as she investigates the murdered priest who was a good friend of her's.

During the finale, where she explains how the murder was done, making everyone think that the killer was one of the people staying at the hotel... >!before outing the "Witness" she has brought as the killer, revealing she knew it was he who killed her old friend because he's a greedy, wicked and stupid little bastard who has been tricking women into helping him with the murders by running a consumer research company on the side and replacing items in their home with poisoned substitutes!<. She's just barely holding back in anger as she breaks down their incompetence and how easy it was to make him think she was going to die that the guy tries to kill her right then and there.

Because smart people love showing their smartness, also for the viewer to understand.

Confessions are covered under the "statement against interest" exception to the hearsay rule. They're therefore admissible as evidence if obtained under otherwise proper circumstances, and they might cement a case where other evidence is weak.
