Is there an offence when you kill to prevent a murder? Suppose Person A shoots and kills Person B, who was about to shoot to kill Person C, and Person C makes a statement to police to say that if Person A hadn’t intervened, there was no doubt they would have died (i.e. Person B actually pulled the trigger, and only missed due to a bullet to the head). In the United Kingdom, what crime could Person A be charged with? What might be the minimum sentence, if they can be found guilty?
Murder Which is the unlawful taking of a life with intent to do so. However, the doctrine of self-defence can make killing lawful: A person may use such force as is reasonable in the circumstances in the prevention of crime, or in effecting or assisting in the lawful arrest of offenders or suspected offenders or of persons unlawfully at large. if the prosecutor is of the opinion that the force used "is reasonable in the circumstances" they may not lay charges. If they do lay charges the judge may decide that there is no case to answer before going to trial if self-defence applies. If there is a trial this will probably be the strategy the defence employs and they may or may not be successful. If convicted the penalty is life imprisonment. Also, there is no UK law: there is the law of England and Wales, the law of Scotland and the law of Northern Ireland.
Any country is free to decide what actions are considered to be crimes, and what crimes are prosecuted depending on whether you perform the action in the country, outside the country, and depending on whether you are a citizen, a resident, both, or neither. They can also decide what are accepted defences in court and which are not. Any other country is free to decide under which circumstances they will ever extradite someone to that first country. Now you have to check the laws of the individual countries.
There is a big difference between knowing something and proving it. A lawyer who knows a client is guilty can take steps to prevent the state from proving guilt. (E.g., motion to exclude evidence, cross examining witnesses.) The belief that a client has committed a crime does not necessarily mean one knows what specific crime was committed. Is a killing Murder 1, Murder 2, or manslaughter? There are defenses even when an act may be a crime. E.g., self defense, insanity, justifiable. Lawyers are not permitted to assist in perjury. E.g., allow the client to testify to something he knows is false.
This is manslaughter of the vehicular variety Manslaughter is the unlawful killing of a human being without malice. It is of three kinds:... (c) Vehicular— (1) ... driving a vehicle in the commission of a lawful act which might produce death, in an unlawful manner, and with gross negligence. This is what they call a wobbler, and could be charged as a felony or a misdemeanor. In the latter case, the maximum penalty is a year in county jail and in the former it is six years in state prison. If the cause was ordinary negligence, it is just a misdemeanor. The details of gross negligence are set forth in the jury instruction CALCRIM 592 A person acts with gross negligence when: He or she acts in a reckless way that creates a high risk of death or great bodily injury; AND A reasonable person would have known that acting in that way would create such a risk. In other words, a person acts with gross negligence when the way he or she acts is so different from how an ordinarily careful person would act in the same situation that his or her act amounts to disregard for human life or indifference to the consequences of that act. The "absent-mindedness" defense seems a bit far fetched, but still not everybody who drives inattentively is prosecuted for a felony, or even a misdemeanor. However, it is really hard to imagine not being acutely aware of the fact that people drive on the right side of the road here. Without a more-detailed story, I don't see a basis for deciding what level of negligence a prosecutor is likely to argue for, and what the prosecutor's agenda is: somewhere between no prosecution, and (most likely) misdemeanor manslaughter.
england-and-wales It depends on Alice's belief about who Mallory is and what Mallory is doing and whether Alice's force was reasonable. If Alice is aware that Mallory's action is lawful, then Alice cannot use force to protect Bob. Is Mallory a doctor who is lawfully withdrawing treatment? (You say there is &quot;no law allowing Mallory to disconnect Bob's life support&quot; but I'm not aware of a jurisdiction that requires indefinite treatment regardless of the circumstances.) If Alice honestly believes Mallory is attempting to unlawfully kill Bob, Alice can use force to protect Bob. Is Bob on life support because of Mallory's previous attempt on his life; is Mallory a hitman, a vengeful spouse or some other person with no lawful reason to kill Bob? Crown Prosecution Service guidance: Self-Defence and the Prevention of Crime: Self-defence is available as a defence to crimes committed by use of force. The basic principles of self-defence are set out in Palmer v R, [1971] AC 814; approved in R v McInnes, 55 Cr App R 551: &quot;It is both good law and good sense that a man who is attacked may defend himself. It is both good law and good sense that he may do, but only do, what is reasonably necessary.&quot; The common law approach as expressed in Palmer v R is also relevant to the application of section 3 Criminal Law Act 1967: &quot;A person may use such force as is reasonable in the circumstances in the prevention of crime, or in effecting or assisting in the lawful arrest of offenders or suspected offenders or of persons unlawfully at large.&quot; ... In assessing the reasonableness of the force used, prosecutors should ask two questions: was the use of force necessary in the circumstances, i.e. Was there a need for any force at all?; and was the force used reasonable in the circumstances? The courts have indicated that both questions are to be answered on the basis of the facts as the accused honestly believed them to be (R v Williams (G) 78 Cr App R 276), (R. v Oatbridge, 94 Cr App R 367). To that extent it is a subjective test. There is, however, an objective element to the test. The jury must then go on to ask themselves whether, on the basis of the facts as the accused believed them to be, a reasonable person would regard the force used as reasonable or excessive.
No. It is illegal to hire someone to kill someone else. Even if the killer enjoys diplomatic immunity, the person hiring the killer has committed a crime. As to your last paragraph, that is properly a separate question, but the answer is that they can't do it because murder is illegal.
It looks like this is covered by article 34 of the criminal code you linked: ARTICULO 34. - No son punibles: [...] El que obrare en defensa propia o de sus derechos, siempre que concurrieren las siguientes circunstancias: a) Agresión ilegítima; b) Necesidad racional del medio empleado para impedirla o repelerla; c) Falta de provocación suficiente por parte del que se defiende. Se entenderá que concurren estas circunstancias respecto de aquel que durante la noche rechazare el escalamiento o fractura de los cercados, paredes o entradas de su casa, o departamento habitado o de sus dependencias, cualquiera que sea el daño ocasionado al agresor. Igualmente respecto de aquel que encontrare a un extraño dentro de su hogar, siempre que haya resistencia; English (my translation, no guarantees): ARTICLE 34 - Not punished are: [...] Someone who acts in self-defense or in defense of their rights, as long as the following circumstances apply: a) illegitimate aggression b) a rational need for the means used for preventing or repelling the aggression c) a lack of sufficient provocation on the part of the defender It is understood that these circumstances apply with respect to someone who during the night defends from a housebreaking or a breach of the enclosure, the walls or entrances to their home, or the home of their dependents, no matter what damage is caused to the attacker. Reading these rules, which look quite similar to the law in most other countries, I'd say shooting an armed intruder would be covered. It would probably already be covered under the general rules ( a) to c) ): There is an illegitimate aggression, and shooting is necessary for stopping the agressor, because no milder means is practical in the situation. Additionally, the last paragraph would apply, which provides additional protection to someone defending their home, so even if a judge decided that normally shooting someone attacking with a knife is not necessary for protection, it would still be ok for home defence.
There are problems with the claims. In summary: someone that in Sweden acts to defend themselves while &quot;in peril&quot; when subjected to — or are in imminent risk of — a criminal attack, will not the convicted, unless the act is &quot;blatantly unjustifiable&quot;. Context We have a problem here in Sweden with people being ill-informed about the right to self-defence, and this is compounded by people with opinions spreading myths about it. Often these myths err on the side of claiming you have less rights than you really have. So, two things before we go on... The characters may have been unreliable. Do not ever assume that just because a character says something in a work of fiction, that the character is meant to know what they are talking about. And even if they are meant to know what they are talking about... The author may have been unreliable, and done their homework poorly. Keep this in mind... That said, the right to self-defence is not infinite. The law According to the Swedish Criminal Code (Brottsbalk, 1962:700), Chapter 3, §§ 1-2 and 6... If you intentionally kill someone, you get convicted of &quot;murder&quot; If you intentionally kill someone, but there were mitigating circumstances, you get convicted of &quot;manslaughter&quot; If you act in reckless disregard for the risk your actions are causing, and this leads to the death of someone, you get convicted of &quot;causing the death of another&quot;, or what we here can call &quot;reckless killing&quot; And Swedish Criminal Code (Brottsbalk, 1962:700), Chapter 24, § 1 states that an act performed in &quot;peril&quot; shall only lead to a conviction if the act was &quot;blatantly unjustifiable&quot;. &quot;Peril&quot; is enumerated to exist in cases of... A commenced or imminent criminal attack on person or property A person has gained or trying to gain unauthorized access to a room, house, yard or ship A person refuses to leave a domicile after being told to If — when caught red-handed — a person uses violence or threats of violence to resist stolen property from being retaken When judging whether an act is &quot;blatantly unjustifiable&quot;, the prosecutor must look at... the nature of the attack that caused the peril the significance of that which the attack was aimed at (such as a human life) other significant circumstances That last bit is interesting because it takes human psychology into consideration, and let the defendant's assessment of the peril be the standard by which the act is judged. The claim Let us start with the easy bit first... &quot;if she killed the intruder, under Swedish law, she could very well be charged with manslaughter, and possibly murder if it could be proved that she placed the golf clubs around the house ahead of time.&quot; Murder? No. According to the Swedish Criminal Code (Brottsbalk, 1962:700), Chapter 3, §§ 1-2, a person that kills an intruder in their home could at the most be charged with manslaughter, because there are mitigating circumstances, i.e. the person felt threatened and there was a home invasion in progress. In order for this to become murder, she would more or less have to have invited the assailant or in any other way drawn them in with the intent to kill them. Yes, she prepared to defend herself or a potential intrusion, but without knowing for certain that the assailant would come at certain time or at least a certain day, any kind of premeditation towards killing is more or less impossible to prove. With this, murder is off the table. That claim is simply wrong. Whether it is the author or the character that is erring, I cannot say. So, manslaughter then, or the even lesser degree, called &quot;causing the death of another&quot;, or reckless killing. Manslaughter would come up of she — when whacking them with the club — did so with the intent of killing them. The operative word here being intent. The prosecutor has to prove that intent. Sure, we can dream up scenarios where this is the case; the classic reason for why people do get convicted even acting in peril is when they keep harming the assailant after the danger has passed. But — again — just preparing for a potential intrusion is not enough to prove that intent. Finally, reckless killing. This is where such cases usually ends up. And — again — this usually happens because the defendant did something when the danger has obviously passed; the criminal attack was no longer imminent but passed. Conclusion Unless the protagonist in question had set up lethal traps; unless they had foreknowledge of an attack; unless they invited the assailant in with the intent to kill them; unless they fend off the attack and gets themselves into a perfectly safe situation and then proceeds to beat the assailant to death; and unless all of this can be proved, then it cannot become murder. Manslaughter or reckless killing, yes, there will be an investigation for that, but from the description of the situation — the protagonist fearing the assailant is dangerous and means them harm — preparing a home defence with strategically placed golf clubs does not in any way preclude the prosecution being dismissed as justifiable self-defence. Only(!) if the home invasion was obviously harmless, and/or the protagonist keeps harming the assailant after the home invasion has been staved off / neutralised, can a conviction for manslaughter or reckless killing become a possibility. Summary Yes, in Sweden a prosecutor will look at the case when you kill someone. But — no — in the situation described, a home invasion by someone perceived as wanting to cause harm, this is very unlikely to become &quot;murder&quot;, for lack of premeditation. The remaining possible charges — manslaughter or reckless killing — will only result in a conviction if the situation was obviously and provably harmless in the eyes of the defendant, and they still killed the assailant.
