Is it legal to steal a car to save your life when your life is in danger? Person A is bein chased by person B who is carrying a knife. Person A has good reason to believe that if person B catches him, his life will be in danger. As person A runs away, he sees a convertible car with the keys in it. The top is up. He does not know who owns the car. Can he get into the car, start the engine and legally drive away to safety? I am in the United States.
If it is necessary, yes Generally, the defendant must affirmatively show (i.e., introduce some evidence) that (a) the harm they sought to avoid outweighs the danger of the prohibited conduct they are charged with; (b) they had no reasonable alternative; (c) they ceased to engage in the prohibited conduct as soon as the danger passed; and (d) they themselves did not create the danger they sought to avoid. The necessity defence is recognised in most common law and civil law jurisdictions and in international law. In common law jurisdictions, the “harm” must be some sort of clear and imminent peril to life and safety, such as the situation you describe (although B needs to prove all the elements). In civil law jurisdictions, the peril can be more distant such as the successful defence in 2020 in Switzerland of protesters using it where the threat was climate change.
The legality of the stop may be somewhat up in the air, but it would seem that the vehicle is not in the Texassure database, so it is reasonable to think that the person driving is not insured, and therefore is breaking the law. And that is all that is required: that the suspicion is reasonable. Until someone makes a sufficiently persuasive legal stink about this, it is probably a legal stop. This article gives some legal discussion. One applicable case is US v. Broca-Martinez, a Texas case where a person was pulled over for being "unconfirmed" w.r.t. the insurance database: the court held that this was a reasonable suspicion. Thereafter, a charitable interpretation is that you misunderstood the request in providing your sister's information when he asked for your license and insurance: but you are expected to understand that when they request your license and proofs of insurance, they mean you the driver, and not the car owner. That they is even more suspicious, although I understand your confusion. At your hearing you cane explain why you didn't comply with the first officer's request, and the judge may they chalk this up to a simple misunderstanding rather than intentional deception. The problem is that you are expected to know – whether or not you've ever been pulled over before – that you have to provide license, registration, and proof of insurance. You will have a hard time making it believable that you didn't understand what the officer told you and what the law requires.
A person's property cannot be seized in the US except by due process of law. There is no law that declares the property of a convicted person to be forfeit to the state. A person who is convicted might be subject to a fine, in which case a court could order seizure of property to pay the fine. Your property might also be seized as a result of a civil forfeiture proceeding (where the government sues your property for being the fruit of an illegal enterprise), but that only applies to property believed to be connected to a crime (e.g. purchased with the proceeds of a crime). Civil forfeiture doesn't even require that you be arrested. Barring that circumstance, the person retains their rights to their property. It is then up to them to make suitable arrangements for the protection or disposition of their property.
Theft is of course illegal in all US states, and pretty much every other jurisdiction. In the US that is a matter of state law, not federal. It could be reported to the local police, but it might be hard to prove. Both landlord/tenant law and privacy law are largely matters of state law in the US, not federal law. Such laws vary a good deal in different states. In many states a landlord is allowed to enter the rented premises, usually on "reasonable" notice, or without notice if there is an emergency. If the landlord actually lives in another part of the house, and simply rents a room to the tenant, the landlord may be able to enter the room more freely than if it was a separate apartment or house. In many cases where there is a written lease or rental agreement, it will specify under what conditions the landlord or landlord's agent may enter, and how much notice is required. What does the lease in the current case say about that?
From a comment on the question: They did damage the trailer door and headlight is smashed This seems like the best thing to focus on, especially if you can show that it was not damaged before they towed it. The unusual method of towing (with video evidence) may be a factor in whether they are considered negligent. If the damage to the door looks like they caused it directly by breaking in, that would also help your case. You also asked in your comment if you should go to the police or to a lawyer first. Might as well go to the lawyer and see what they tell you to do. I'm not sure what the police would do if there is no clear crime that has been committed. (The lawyer should have better advice about whether/why to go to the police.)
Is this interpretation correct? YES Encounters such as this should normally fall within the non-statutory stop &amp; account which covers police-initiated conversations with members of the public to ask general questions about their activities when there are no reasonable grounds to suspect an offence. The terminology varies from Force to Force, but can be summarised as: What are you doing? Why are you in the area? Where are you going? What are you carrying? There is no legal requirement or obligation to answer any of these questions, and the police cannot lawfully detain anyone to ask them - unlike the statutory powers under Stop &amp; Search and Arrest covered by the OP.
I'm not sure there would be any need - or any ability to bring - any civil action. Forgery would appear to count as a Category D felony under Section 205.090 and, "In addition to any other penalty, the court shall order the person to pay restitution.", so person "a"'s damages should have been met under the process of the criminal prosecution of person "b" for forgery, with nothing further to claim. Person "c" will have stolen a car. Whether that car was legitimately owned by person "a" may only be relevant if person "c" is using their belief that it belonged to person "b" as mitigation (for example recovery of a debt - though it won't help much as this should have been done through proper channels), which again would be a criminal proceeding.
While it is from a different jurisdiction, the following goes to the heart of the matter: Arrest, when used in its ordinary and natural sense, means the apprehension of a person or the deprivation of a person's liberty. The question whether the person is under arrest or not depends not on the legality of the arrest, but on whether the person has been deprived of personal liberty of movement. Directorate of Enforcement v Deepak Mahajan, (1994) 3 SCC 440 at ¶46 (SC of India) In your example, the police officer has been deprived of "personal liberty of movement"; if they can still speak there would be no legal impediment to them placing the person who arrested them also under arrest. It would then be incumbent on both parties to deliver each other into lawful custody. The citizen would need to seek out a law enforcement officer to do this; the police officer has already done so, being their own law enforcement officer. After this, comes the paperwork.
