Suppose an effective truth serum existed. Could defendants in the following situations have their confessions ruled inadmissable? Suppose a "Hollywood style" truth serum existed, whereby if a person is given the serum, that person is compelled to truthfully answer any question put to them. The following facts are true in all of the scenarios: Clyde Criminal commits a crime Victoria Vigilante catches him in the act, injects him with truth serum, and leaves him for the police Victoria Vigilante leaves, Officer Olivia arrives a few minutes later Clyde's best bet is to exercise his right to remain silent until the serum wears off. But what would be the value to the prosecutor of Clyde's confession if he confessed under these various circumstances: Before Olivia speaks, Clyde confesses to the crime. After Olivia reads Clyde his Miranda warning, but without being asked any questions, Clyde confesses. After the Miranda warning, Olivia asks Clyde "What happened?". Clyde confesses. After the Miranda warning, Olivia asks Clyde "What happened?". Clyde says "I would prefer to remain silent, but I can't stop myself from telling you..." Clyde then confesses. Before Olivia arrives, Victoria questions Clyde and records his confession. Victoria then leaves Clyde and the recording for Olivia to find.
Miranda rights do not attach until the suspect is subject to custodial interrogation. "Custody" means that the suspect reasonably believes that he is not free to leave the conversation. "Interrogation" means that the officer is engaging in direct questioning or other conduct that would reasonably be expected to elicit a response. A suspect is free to waive his Miranda rights and begin speaking without a lawyer, but a waiver must be knowing, intelligent and voluntary. "Voluntary" means that the waiver is obtained without coercion (torture, threats or promises) by the government. None of the five scenarios indicate that Clyde ever believes he is in custody, so he has no Miranda rights in any of them, making his confession admissible in all of them. But to play it out further, let's assume that Officer Olivia arrives and immediately slaps handcuffs on Clyde: No interrogation, no Miranda rights. The confession is admissible. No interrogation, no Miranda rights. The confession is admissible. Miranda rights attached at the beginning of questioning. Clyde waived by confessing. Reading the Miranda rights established that the waiver was knowing. We don't have any facts suggesting the waiver was not intelligent. The waiver was not obtained by government coercion, so it was voluntary. The waiver was effective, so the confession is admissible. Same as 3. No interrogation, no Miranda rights. The confession is admissible. The key thing to keep in mind here is that the purpose of the Fifth Amendment right against self-incrimination was to avoid misconduct by the government, and it has generally been implemented only to that end. The key case here is Colorado v. Connelly, 479 U.S. 157 (1986), which involved a guy who approached a police officer and asked to talk about a murder he had committed. The officer Mirandized him, and he told them all about the murder and where he buried the body. It turned out that he was a chronic schizophrenic and was going through a psychotic break at the time of the confession, which he had only offered because "God's voice" told him to. As with your truth serum scenario, the question became whether the Miranda waiver satisfied the voluntariness requirement. The Colorado Supreme Court held that "capacity for rational judgment and free choice may be overborne as much by certain forms of severe mental illness as by external pressure." But the U.S. Supreme Court reversed, holding that neither the defendant's due-process rights nor his right against self-incrimination are offended by non-governmental influences, even when they undercut the defendant's free will. Since then, other courts have relied on Connelly to hold that voluntariness was not defeated by: a suspect's flu, hangover, hunger, or exhaustion, U.S. v. Elwood, 51 F.3d 283 (9th Cir. 1995); a suspect's heroin use, Elliott v. Williams, 248 F.3d 1205, 1213 (10th Cir. 2001); a suspect's heroin withdrawal, U.S. v. Kelley, 953 F.2d 562, 565 (9th Cir. 1992); a suspect's orders from his father, N. Mariana Islands v. Doe, 844 F.2d 791 (9th Cir. 1988); or a suspect's unusual susceptibility to suggestion or intimidation, U.S. v. Guerro, 983 F.2d 1001, 1004 (10th Cir. 1993). tl;dr: Because the truth serum was not administered by the government, the confession is admissible in all five scenarios.
There is no direct equivalent to the American-style plea bargain, but there are some similar procedures: Basis of Plea A defendant can offer a written guilty plea to a lesser offence with the same (or closely similar) facts as the offence charged, which has to be accepted by the court to take affect. The prosecutor must consult with and seek the views of all victims, and if the plea is accepted it must not be misleading or untrue. The Attorney General's Guidance provides more information on the process and the detailed requirements (which are too long to repoduce here). Assisting Offenders The Serious Organised Crime and Police Act 2005 offer the option for a &quot;minor-player&quot; defendant to assist the prosecution and/or police by providing information to secure convictions of the principle offenders in return for immunity from prosecution (section 71), a restricted use undertaking (a version of immunity) (section 72) or a reduced sentence (section 73). Immunity requires full and frank disclosure of all previous offending (referred to as &quot;cleansing&quot;), but for whatever reason the defendant does not &quot;cleanse&quot; they may still be eligible for a lesser sentence. Either way the assistance - either as evidence at trial or as intelligence given in confidence - should be substantial and verifiable to be eligible. Statistics There is, as far as I can, no publicly available detailed statistics on these procedures, presumably the reason is that vast majority of the former cases go unreported and, despite some being public, there is a real risk of retribution to the informant in the latter.
This is covered by Rules of Federal Criminal Procedure Rule 11, which says that Before accepting a plea of guilty or nolo contendere, the court must address the defendant personally in open court and determine that the plea is voluntary and did not result from force, threats, or promises (other than promises in a plea agreement). The judge is not required to include a disclaimer (like &quot;other than the plea deal itself&quot;) in interviewing the defendant. By asking the question in an unqualified way, the judge will decide whether there were promises made that are outside the scope of the plea bargain.
A party to a civil suit in a US court generally has wide latitude on discovery. If it is not completely implausible that one of those text messages might contain something helpful to the other side, then they might well be able to demand and obtain them. This would be true even if Jan has no plans to use any of them. If Jane thinks that there is something in some of those messages which should not be disclosed, she could, normally with the advice of hr lawyer, file a motion to limit discovery in some way. Whether there is good grounds for such a motion will depend on very specific details of the facts, and is beyond the scope of an answer at this forum. It is true that Jane is only required to produce the messages if the judge in the case has in fact ordered this. It would be highly unethical for Jane's lawyer Arnold to lie to here about this. If he did so and got caught, it might cost him his license to practice law, plus additional penalties. If Jane seriously suspects that he is outright lying to her, and colluding with the opposing party, she needs to take steps to confirm or disprove this, or if she can do neither, to obtain a different lawyer.
Even before the police have any idea who did it, Bob is guilty of whatever wrong he did. However, if you want this to be a legal question and not a moral one, we should assume that you really want to know "Can Bob be convicted of murder, if the evidence proves that he did do it?". Yes, he can. See Morris v. State, 214 S.W.3d 159. The critical question was whether the defendant understood the charges (he did) and whether he could assist in his defense (he could). The desideratum of being able to assist in your own defense only goes so far. On the other hand, maybe no, per Wilson v. US. A government expert witness "testified that appellant had permanent retrograde amnesia and would not be able to aid in his own defense in terms of remembering any of the acts alleged in the indictment". The crucial difference seems to be whether one just has loss of memory, vs. loss of memory connected with some other mental disorder. [Addendum] Per Dusky v. United States 362 U.S. 402, competence to stand trial depends on whether the accused has sufficient present ability to consult with his lawyer with a reasonable degree of rational understanding -- and whether he has a rational as well as factual understanding of the proceedings against him. I am not aware of any exceptions e.g. whether this is not the case with strict liability crimes like statutory rape, and since it is generally held that "competency" is a requirement mandated by the due process clause, I don't think there could be an exception.
An appeal to ignorance asserts that a proposition is true because it has not yet been proven false. That is not in any way the situation here. The defendant knows if he/she has or has not so the only available answers under oath are "yes" or "no" - the jury knows this too so any other answer will be seen as disingenuous. However, this information (affirmative or negative) is off limits to the jury as it could prejudice their decision, hence the mistrial. A quick judge could instruct the defendant not to answer and instruct the jury to disregard the question but if a conviction results the defence team could use the fact that it was asked as grounds for appeal. A judge must decide if the interests of justice are better served by a retrial or a tainted conviction.
Yes and no. There are numerous cases where criminals, upon breaking in to somewhere, find evidence of a worse crime and notify authorities. This will provide reasonable suspicion enough for entering the scene. Generally, in testimony, Statements against Interest are more believable because a burgler wouldn't admit to breaking and entering if he had a way to explain why he was there in the first place. (Example: Alice breaks into a Warehouse and sees a mutilated body and blood everywhere. Alice immediately stops her theiving ways and calls 911 to let them know about the scene. Whether or not Alice stays, a dead body is enough probable cause to secure the crime scene without warrant. Its in Alice's interests to stay and help as there is trace of her at the scene and she would be pegged as a suspected murderer. If she's picked up and admits to calling the cops, it's good, but staying and helping out after the call will likely get her off on the charges related to the murder.). It could also work if they are persuing one crime and discover evidence of a second unrelated crime. (i.e. Alice robs the factory and gets away. The Factory Foreman calls the cops to investigate the crime scene, which at this point, does not need a warrant. While investigating, the Cops find security footage that Bob, the night guard, killed Chuck, a late night worker, removed his body, and cleaned the scene, all before Alice broke into the factory. The outcome of the case being made against Alice does not affect their need to prosecute Bob, as they obtained that evidence while looking for Alice in a valid investigation, not Bob, thus it is legal). Under these situations a crime that leads to a separate valid crime involving a different party is admissible. There are two possible reasons that the attorney might think this: Fruit of the Poisonous Tree: This is the obvious element... the kids committed a crime with the hopes that the cops would use the evidence found by them in their commission of a crime to get the real bad guys. The attorney parent thinks this is stupid because the kids broke in specifically to do this and thus any evidence is now tossed out of court. This isn't usually the case in how this scenario will play. Generally the cops are more than happy to look at evidence obtained by criminals that points to another crime. In fact, this is how a lot of gang enforcement units and drug enforcement units operate... pick up a small fish and cut a deal for evidence against a bigger fish (turning state's in the criminal lingo, as the witness is becoming State's Evidence to another crime). As long as it's given to the cops as part of legitament evidence seeking, the cops can follow the leads where ever they... er... lead... Chain of Custody: This is probably, if properly thinking, what the attorney parent is thinking that's a bit more probable. Lets say these kids found a dead body with a sword in it and take the sword to the police... this could get dicey as the kids have contaminated the evidence in possible ways that the killer's lawyer could get thrown out. One thing CSI doesn't always show (though there are a few episodes where it comes up, but not many) is that when something is taken in as evidence, it is carefully documented, sealed, and tagged with a check in/check out list. Every time the seal is broken, the person breaking the seal notes the time, date, and reason and when does, reseals it with a new seal, and signs the time and date of the seal again. This is so at trial, the attorneys know exactly who opened up the evidence, what they did, and what possible contaminants were introduced. You even have to sign into a crime scene before you go up to the yellow tape. A good defense lawyer would call into question any evidence from anything the kids handled to get the evidence tossed (i.e. Your honor, these Meddling Kids handled the sword without following the chain of evidence. They even let their dog handle it. They had already harrassed my client earlier today by insunuating that he was involved with a hoaxed paranormal activity to scare people away from the factory. Since they claim they found the sword, but did document it at the scene, we don't know anything about it prior to the police's chain of custody. I motion that the evidence be dismissed.) If this is successful, anything from the sword is now no longer admissible as if the sword had never been found (including blood of the victim on the blade and finger prints of the suspect on the hilt)... in effect the evidence was prossessed as best the police could but the veracity of the story of it's discovery is too questionable to be considered. The defense does not have to be right, he just has to show there could be another explanation for the sword and the evidence linking his client to the crime committed by it. In short, without specific details, the attorney parent could be right or could be wrong, or more humorously, right, but for the wrong reasons. Edit: U.S. only. See other answers for other jurisdictions.
You misunderstand the significance of the phrase "innocent until proven guilty." This is in part because you are not considering the entire phrase. The full phrase is that an accused party is "presumed innocent until proven guilty." This does not mean that the accused is innocent, only that criminal procedure must take as its starting point that the accused did not commit the crime. The major implication of the presumption, and indeed its original purpose, is that it places the burden of proof on the prosecution. This means that if a prosecutor asserts that you stole something, you do not have to prove that you did not. Rather, the prosecutor must prove that you did. The only reason to present evidence of your own is to rebut the prosecutor's evidence. Another practical implication is that a decision to detain someone awaiting a criminal trial may not be based on the assumption that the accused committed the crime. On the other hand, that decision is not based on the assumption that the accused did not commit the crime. There is a presumption of innocence, but no assumption of innocence, and the government is not obliged before the person is convicted to treat the person as if there is no accusation or charge. Wikipedia has a decent discussion. If we modify your question accordingly, it becomes How can two people be presumed innocent until proven guilty if their stories conflict? Now the answer should be clear. The prosecutor must develop evidence that shows which one of the people has committed the crime. If the prosecutor cannot do that, neither person may be punished.
