Can law enforcement legally force someone to unlock a device themselves in the US? We're all likely aware of the big Apple vs FBI case where the FBI wants to force Apple to open a back door in its encryption on iPhones, and we'll soon discover what the law will decide on that, but it got me thinking: Obviously a subject could claim that he forgot his password, so that's a dead end, but with fingerprint scanners on new iPhones that leads to a few possibilities. Could the FBI legally do any / all of the following? Why or why not: Retrieve fingerprints from a surface the subject makes contact with while in custody to artificially pass the fingerprint scan on an iPhone. Force the subject to place his finger on the fingerprint scanner.
Here's what one recent law review article says: While the privilege against self-incrimination bars compelling communications or testimony, compulsion that makes the suspect the source of physical evidence does not. Given that biometric authentication is merely a scan of physical traits that are compared to previously stored information, one can argue that compelled biometric authentication is not barred by the self-incrimination privilege. Indeed, the Supreme Court has repeatedly held that compelling an accused to demonstrate physical characteristics for identification purposes does not qualify as compelled self-incrimination because it is not testimonial in nature. Likewise, if an accused was compelled to place his finger on his laptop's fingerprint reader, or have his face scanned with his phone's facial recognition software, the physical characteristics would have been used for identification purposes and would likely not be considered "testimonial in nature" such that the scan would violate the self-incrimination privilege.

You cannot legally force police to wait to carry out the search. They can search even if you are not present. In fact, they are required to execute the warrant within a certain time frame, which precludes delaying the execution of the warrant. You can inspect the warrant to see if it is &quot;proper&quot; (has the judges name, correct address, is a search warrant and not a warrant of removal/deportation...). Calling a lawyer is always wise, but that does not stop the search.
If there is no reasonable suspicion of a crime having been committed or about to be committed, then there is no reason to seize you, and the Fourth Amendment "right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated". Even if a state has a "stop and identify" statute, reasonable suspicion is a minimum requirement for seizing your person, even temporarily. Texas is not a state with an obligation to identify statute. I would not expect the state to be very helpful, given the facts as you report them. There might be others, such as the ACLU, who may be happy to discuss the particulars of your case. The police need to justify a stop in court, and not to the person being seized. I don't know if there is any case law saying that a false police statement to a detainee ("No, I don't have a reasonable suspicion") precludes claiming in court that there was reasonable suspicion, but it should at least make the claim of reasonable suspicion less credible. They do have to have reasonable suspicion, and they do not have to tell you what that suspicion is. OTOH if they are just harassing bicyclists, that would be illegal.
In general, people have less expectation of privacy in cars than in their homes. To challenge a search and/or seizure under the Fourth Amendment, a person must have standing - the right to sue (that is, you must have had a reasonable expectation of privacy in the place where the search happened; if you didn't, no standing - can't claim your privacy was violated if you had no privacy). The US Circuit Courts are split on the issue of unauthorized rental drivers and whether they have the same reasonable expectation of privacy as the authorized driver of a rental car would have. Some Circuits allow the unauthorized driver to challenge a car search if the authorized driver gave them permission. Some Circuits look only at the agreement and if the driver isn't authorized on that, they're out of luck. The 6th Circuit is more case-by-case, with a presumption that driver can't challenge the search that can be overcome based on the facts. (All this info from US v. Haywood, 324 F.3d 514) There's a current case before the Supreme Court (argued January 9, 2018), Byrd v. US, on this very issue. This SCOTUSblog page has a lot of information on the case. Edited to add: Texas is in the Fifth Circuit, which follows the rule that unauthorized drivers don't have standing to challenge a search/seizure even with the authorized driver's permission to drive the car; unauthorized drivers of rental cars don't have a reasonable expectation of privacy because they lack a possessory interest in the car and/or they're violating the rental agreement. Basically, even though it seems the cops' stop of the car would've violated the Fourth Amendment if he were the authorized driver, since this happened in Texas, he's not going to be able to challenge the stop. IMO, this is incredibly unjust especially when the cops admitted there was no probable cause, so hopefully the Supreme Court makes this rule obsolete and allows unauthorized drivers to exercise their Fourth Amendment rights.

If the FBI has reason to believe they have committed a crime under US law Being an official of a foreign (or domestic) government in a military or civilian capacity does not make a person immune from US law except in the specific case of diplomatic immunity. There are some US laws that apply even if the perpetrator is not and has never been in the US, for example, computer hacking and fraud. So, if the FBI has probable cause they can ask for and get an arrest warrant. If the US were at war with this person’s country then, barring war crimes or crimes against humanity, military action against the US is not a crime. Naturally, exactly the same circumstances apply to US citizens vis-a-vis foreign laws.
There are two issues, one is the legal issue of whether what you are doing is a crime, and the other is the evidentiary issue of proving that that is what happened. If you take the phone home with the intention of keeping it ('finders keepers') then you have committed larceny (sometimes called 'theft', sometimes correctly). This specific type is called 'larceny by finding'. If you take the phone home with the intention of finding the owner then you have not committed larceny because you have not committed the mental element ('mens rea') of the offence: you don't intend to permanently deprive the owner of their rights. However, and this is the evidentiary issue, if hypothetically you were found in possession of the phone then the police might not believe your explanation and a court might well convict you of larceny. P.S. Firefox has marked 'evidentiary' as a spelling error and suggested 'penitentiary' instead. :s
Absolutely not. Lack of authority Law enforcement officers do not have the authority to grant immunity from prosecution. The decision to prosecute lies with the district attorney's office. Courts have sometimes held that a promise of immunity by a police officer can make resulting statements inadmissible, but that's it -- the state is not bound by the police officer's promise to not prosecute, except in exceptional cases. They can gather other evidence and prosecute anyway. Prospective immunity The contract claims to provide immunity against prosecution for future crimes. Contracts against public policy are void, and I'm having trouble thinking of something which is more against public policy than a license to commit crimes. No one can offer that immunity through contract. In a recent trial of a Boston mob boss, he attempted to claim that a federal prosecutor had given him immunity for any and all future crimes for some time period; the court did not accept that, because a license to break the law is not a valid contract. Public authority There is a situation in which certain officers can grant authority to break certain laws: to catch bigger criminals. However, for fairly obvious reasons, there are extremely strict rules on when this is valid, both on the government procedure side and the claiming-the-defense side. The defense can only work if the defendant honestly believed the government had authorized his actions, if the government actually had authorized them, or if he followed official government legal advice. In this case, the defendant has no idea if government officials have agreed to the terms; he would have approximately no chance of convincing anyone he legitimately thought that the government approved of his actions. They certainly wouldn't be actually properly authorized, and he hasn't sought advice from the government. Other issues Police aren't the only people on this site. An investigation tends to involve one or more non-government agents who provide testimony in court. No contract with a private party can stop them from testifying in a criminal trial; certain relationships mean testimony isn't allowed (e.g. a lawyer can't testify about dealings with their client without client permission), but regular users could be required to testify against the site operator (possibly on the basis of actual immunity). Sources Public authority stuff: this Justice Department page, plus some discussion in this order. Prospective immunity: that same order. Lack of authority: myriad readings.
This very much depends on where you are. Different jurisdictions have wildly different laws about this. Some places are very permissive. You can record a conversation that you aren't even a party to so long as nobody has any reasonable expectation of privacy. In others, affirmative consent is required from every party to a conversation before it's legal to record it. The laws run the entire spectrum. Some places allow you to record anything you're a party to without permission, but you can't record others' conversations. Some places require you to disclose, but not obtain explicit permission. Some allow you to record but restrict who you can disclose it to. Some allow you to record or ban recording only under certain circumstances. It's a really wide gamut of laws. Since you don't say where you are, who you're recording, or why, there's no way to really answer the question. Here's a good rundown on the United States. This Wikipedia article covers lots of different countries, but only with regard to phone calls.
