Am I legally able to use lethal force against a police officer in defense of another? Hypothetically, let's say I come across a police officer about to discharge his firearm at a person laying face down on the ground, hands in my clear view, clearly (to me) unarmed and apparently complying with the officer's instructions. Am I legally able to use my own firearm to use lethal force against the officer to protect the apparently unarmed man? How do laws that allow me to use lethal force against the general population apply when the individual I would be defending from is a police officer? Am I obligated to do anything before firing, such as instruct the officer to drop his weapon?
I'll use Washington state as my source, but laws will be similar in other states. RCW 9A.76.020 outlaws obstructing a law enforcement officer, which this would be: it is a gross misdemeanor. In using lethal force, you would have committed first degree murder, under RCW 9A.32.030. There is a defense that can be used, per RCW 9A.16.050, that homicide is justified when: In the lawful defense of the slayer, or his or her husband, wife, parent, child, brother, or sister, or of any other person in his or her presence or company, when there is reasonable ground to apprehend a design on the part of the person slain to commit a felony or to do some great personal injury to the slayer or to any such person, and there is imminent danger of such design being accomplished. Law enforcement officers have access to justifiable homicide defenses as well under 9A.16.040, for example (b) When necessarily used by a peace officer to overcome actual resistance to the execution of the legal process, mandate, or order of a court or officer, or in the discharge of a legal duty or (c) When necessarily used by a peace officer or person acting under the officer's command and in the officer's aid: (i) To arrest or apprehend a person who the officer reasonably believes has committed, has attempted to commit, is committing, or is attempting to commit a felony The outcome of the case would hinge in part on whether the officer's arrest and use of force was lawful. To take two extremes, if the guy on the ground had just killed a dozen people and was aiming to rack up another dozen kills, the officer's arrest would almost certainly be held to be legal and his degree of force justified. Your personal belief that the suspect was compliant and unarmed might be refuted by the facts. On the other hand, if the guy on the ground had slept with the officer's sister and the officer wanted to rid the world of this vermin, then the arrest and force would almost certainly be held to be not legal. It can be legal to use deadly force to resist unlawful arrest. See John Bad Elk v. United States, 177 U.S. 529, where the court held that if a party resisted arrest by an officer without warrant, and who had no right to arrest him, and if, in the course of that resistance, the officer was killed, the offence of the party resisting arrest would be reduced from what would have been murder, if the officer had had the right to arrest, to manslaughter The court also said where the officer is killed in the course of the disorder which naturally accompanies an attempted arrest that is resisted, the law looks with very different eyes upon the transaction when the officer had the right to make the arrest from what it does if the officer had no such right. What might be murder in the first case might be nothing more than manslaughter in the other, or the facts might show that no offense had been committed. This ruling has been somewhat eroded, in US v. Simon: We recognize that law enforcement officers are frequently called on to make arrests without warrants and should not be held, so far as their personal security is concerned, to a nicety of distinctions between probable cause and lack of probable cause in differing situations of warrantless arrests. It is for this reason we believe that the force of John Bad Elk has been diminished The upshot of this is that (assuming no warrant), leeway is granted to officers in assessing probable cause (I'm not sure anybody really knows at a general conceptual level what constitutes "probable cause". The court seems to imply that the remote hearsay used as the basis for the arrest would not have been sufficient for a warrant, but it was "reasonable grounds" for believing accused had committed a crime). Your premise that the officer is about to shoot would have to be substantiated by some fact, such as a declaration "I'm gonna kill you". Otherwise, your belief that the officer was about to commit unjustified murder would itself be unjustified. With better fleshing out of the circumstances, you could manufacture a justified-homicide scenario.
I would just like to clarify, in addition to the other answers and what Dale M alluded to, one important detail: Unless you are carrying out the death penalty, no one under any circumstances is allowed to kill anyone else. What you are sometimes authorized to do, is to use deadly force. There is an important distinction between the two. When using deadly force, you are using extreme force to stop someone doing something, which may result in getting that person killed, but killing isn't the point, stopping whatever he is doing is. If instead of a knife you had a gun on the train, you shot the guy in the face, his crime spree came to and end, yet he was still alive but unconscious, and you decided to "finish the job" and shoot him some more, you'd be going to prison. The language is important. Even if in self defense situations, if you say that you were shooting to kill, you're going to be in serious trouble, but if you say you were shooting to stop, you're in the clear.
canada The person claiming self-defence must have the subjective belief that &quot;a threat of force is being made against them or another person.&quot; Such belief must also be based on reasonable grounds. They must also act with the subjective purpose of protecting themselves or the other person from that use or threat of force. This comes from the text of the defence, codified at s. 34 of the Criminal Code. It reads: 34 (1) A person is not guilty of an offence if (a) they believe on reasonable grounds that force is being used against them or another person or that a threat of force is being made against them or another person; (b) the act that constitutes the offence is committed for the purpose of defending or protecting themselves or the other person from that use or threat of force; and (c) the act committed is reasonable in the circumstances. &quot;Unless the accused subjectively believed that force or a threat thereof was being used against their person or that of another, the defence is unavailable&quot; (R. v. Khill, 2021 SCC 37, para. 52). The National Judicial Institute's model jury instructions slightly rephrases: [the accused] believed that force [or the threat of force] was being used against him/her [or against another person] and [accused]’s belief was based on reasonable grounds Regarding evidence in general: the court needs some evidence on which to give an &quot;air of reality&quot; to every element of this defence in order to place the burden on the Crown to rebut the defence beyond a reasonable doubt. This does not require the accused to testify about their subjective belief. The evidence about the subjective belief can come from elsewhere in the evidence. For example, even if an accused had no memory of the encounter, there may nonetheless be evidence about their subjective belief: video evidence of the encounter, hearsay evidence about what the accused said during the events, physical evidence revealing a defensive posture, etc. The evidence must support an inference of a subjective belief in a threat. It is not enough that the evidence shows that a subjective belief would have been reasonable. But none of that is relevant to the question of what the elements of self-defence are or whether an act taken without the subjective belief that the accused or another person is being threatened is self-defence. The question has helpfully taken the standard approach to legal hypotheticals of just asserting what the facts are in order to take questions of evidence off the table.
Because your buddy routinely points loaded firearms at you First, you should probably get friends who don’t do this but, even though this is objectively a threat, you know that you are in no danger (barring accidents). Self-defence is not justified. This is why there is the dual requirement that the danger is clear to both: an objective observer, and the person under threat.
No. Police are not permitted to impose any punishment whatsoever. Their role in the American justice system is to prevent and investigate criminal offenses. What you're describing is a punishment for a criminal offense, even though it is imposed outside the criminal justice system. The same principles that prevent an officer from punching a suspect in the face or demanding a cash payment to not write a ticket prohibit a police officer from imposing a punishment of his own design, with or without your consent.
ORS 166.220 suggests this would be illegal - specifically its &quot;unlawful use of a weapon&quot; if a person (emphasis mine): Intentionally discharges a firearm, blowgun, bow and arrow, crossbow or explosive device within the city limits of any city or within residential areas within urban growth boundaries at or in the direction of any person, building, structure or vehicle within the range of the weapon without having legal authority for such discharge. So what's &quot;within range&quot;? With a homemade bow of unknown construction, draw weight, and unknown arrows I'd say it's pretty much going to be something you find out when an arrow goes that far. I wouldn't expect it to match the range of high-end bows and arrows (I've seen 40lb recurves cover ~250 yards) but 100 yards plus doesn't sound ridiculous - more if it's got some elevation to it. The point is you really don't want to find out the hard way when a shot goes astray giving your neighbours the old King Harold treatment.
In the U.S. there is no law that requires you to ever say a word to a law enforcement officer, and lawyers generally encourage you to minimize what you communicate to them anyway. I can't think of any situation where a request for information could not be demanded in writing. As a practical matter, in some situations you will probably be subject to some extra scrutiny and inconvenience: E.g., in a stop-and-identify situation, you could hand the officer a note saying, "Please make any requests for information from me in writing." The officer may infer that you have some disability, but if he does not (or discovers you don't) he may get irritated enough to subject you to harassment for "contempt of cop". Of course, if you can understand him, you are still required to obey an officer's lawful orders no matter how they are communicated. But "speak" is not a lawful order.
Illegal weapons Weapons are defined and are made illegal by statute. In many states, it is illegal to possess brass knuckles. For example, California penal code 12020(a)(1) makes it illegal to possess "any metal knuckles", "writing pen knife", "any leaded cane", among other things. I don't know of any state where it is illegal to pick up a stick, or keys, etc. So, yes, there is a legal distinction between your four scenarios. The mechanic is committing a crime by merely possessing the brass knuckles. The others are not committing a crime by the mere possession of the things you mention (unless there are states where they've been made illegal). Effect on a self-defense analysis Courts would have the jury go through the same self-defense analysis in each of these cases, regardless of the legality of the weapon used. We've described that analysis here. A pure self-defense analysis does not factor in the legality of the weapon that is used. But, if the weapon has been made illegal because of its disproportionate ability to injure, etc. that might weigh against the reasonableness of the force that was used when choosing to use that weapon in self-defense. Possession of an illegal weapon might also weigh against the credibility of the owner of that illegal weapon.
