Any law that requires you to allow police to photograph you in public? Lets say you are in public, and the Police approach you. You do not wish to speak to them and want to walk away. They detain you for the purpose of taking a photo of you but you have not committed a crime and they won't state whether you are the suspect of a crime. In the U.S. in any state, is there a law that states you must allow them to photograph you? Can you be charged with obstruction if you actively prevent them from taking the photo by covering your own face?
In general in the US, anyone may photograph anyone else if they are all in a public place, although in some states such a photo may not be used commercially without permission, which must often be paid for and may be refused. It is unusual for police to photograph people on the street, but they might want to document who was present at a particular place and time. They can do so, but I am not at all sure that they can prevent a person from covering his or her face, or turning his or her back, or charge a person who does so with obstruction. I don't think so. Under some circumstances in the US police may ask a person for identification, and may charge a person who refuses to provide it. This varied from one state to another, and usually depends on the specific circumstances. (If a person is driving an automobile, police may demand to see a driver's license, for example.) Unless a police officer puts a person under arrest, the officer has no general right to control that person's actions, beyond instructing the person not to interfere with ongoing police work. I do not think an obstruction charge would hold up for covering one's face or turning away in the absence of an arrest.
There are several misunderstandings here. First of all, the US exclusionary rule applies only to evidence gained by the police, or by people acting as agents of the government, and not always to them. Secondly it applies only in criminal cases. The question does not say which state this would be in, and these are largely matters of state law, so it makes a difference. But I don't know of any state where taking a video without explicit consent, in a place where the person has a right to be, is a crime. In some states it would not even be a tort. If a video is taken without the subject's consent, that may be an invasion of privacy, and the subject might be able to sue (not "file charges). In such a case the video itself would absolutely be put in evidence, and if it recorded verbal permission to take the video, the case would be promptly dismissed, quite possibly with sanctions for a frivolous lawsuit. Even if the video were taken by a police officer, and was presented as evidence in a criminal case, the office could testify to the verbal permission. That would be enough for the judge to view the video as part of a suppression hearing (which is not before a jury). If the judge saw and heard verbal permission to take the video, that would be an end to the motion to suppress, unless it was claimed that the permission was somehow coerced or faked, and evidence supported such a claim.
Staff at polling stations have been told to stop people taking selfies - even though it is not against the law. The Electoral Commission fears the craze for taking self-portraits on phones and posting them on social media threatens the secrecy of the ballot. Anyone who inadvertently reveals how someone else votes in Thursday's local and European elections could face a £5,000 fine or six months in prison. Staff have been urged to put up &quot;no photography&quot; signs in polling stations. https://www.bbc.com/news/uk-politics-27486392 Its not illegal to take a photo of your own ballot paper, it is illegal to reveal how someone else voted without their knowledge. Thats where Section 66 of the Representation of the People's Act comes into play. This law hasn't been updated since the 2014 BBC article, so the articles claims about lawfulness are still valid.
A &quot;police car&quot; doesn't necessarily have a special legal status, so a police officer can theoretically drive a beat-up pickup truck and &quot;be legal&quot; (but not in Washington, see below). What matters is whether others have to give special attention to the vehicle. The pertinent question is, what are the requirements for being an authorized emergency vehicle. I'll give you Washington state law, and you can apply this to other states fairly easily. RCW 46.37.190(1) mandates that Every authorized emergency vehicle shall, in addition to any other equipment and distinctive marking required by this chapter, be equipped with at least one lamp capable of displaying a red light visible from at least five hundred feet in normal sunlight and a siren capable of giving an audible signal. (3) Vehicles operated by public agencies whose law enforcement duties include the authority to stop and detain motor vehicles on the public highways of the state may be equipped with a siren and lights of a color and type designated by the state patrol for that purpose. The state patrol may prohibit the use of these sirens and lights on vehicles other than the vehicles described in this subsection. Given these restrictions, a driver knows whether they must get out of the way, and whether they have to &quot;pull over&quot; (stop driving and get ready for a brief traffic detention). The manner of attachment of &quot;stuff&quot; on the outside of the vehicle falls under general state patrol safety rules, whereby for example you can't balance a rocking chair on the roof and speed down the highway. The state patrol has reasonable discretion to deem that a particular mode of attachment is &quot;unsafe&quot; – this won't be like building-code minutia. Duck tape would probably be deemed to be an insecure means of attachment. There can be some statutory provisions regarding use of private vehicles, for example RCW 46.37.185 allows green lights on firefighter's private care: Firefighters, when approved by the chief of their respective service, shall be authorized to use a green light on the front of their private cars when on emergency duty only. Such green light shall be visible for a distance of two hundred feet under normal atmospheric conditions and shall be of a type and mounting approved by the Washington state patrol. The use of the green light shall only be for the purpose of identification and the operator of a vehicle so equipped shall not be entitled to any of the privileges provided in RCW 46.61.035 for the operators of authorized emergency vehicles. Flashing blue lights are prohibited by WAC 204-21-230(c)(4) &quot;other than a law enforcement vehicle as defined in WAC 204-21-020&quot;, which is &quot;a publicly owned or leased vehicle operated by a law enforcement agency and which is used for the law enforcement functions of the agency&quot;. That means that in Washington, the town sheriff cannot use his personal car as a law enforcement vehicle. I expect there to be some variation on that point across the US. The lights-and-sirens law is what keeps ordinary people from putting lights and sirens on their vehicles.
The question is oddly phrased: The law does not give allowances for its violation. Many laws have exceptions. E.g., the law against killing endangered animals contains an exception for defensive killings. Perhaps you are thinking of safe harbors? For example, there are general provisions in the law like "exigent circumstances" that allow police to proceed with actions that, absent those provisions, would constitute violations of law. "Permission" to violate a right can be granted explicitly in the form of a warrant, which allows law enforcement to "violate" specific property and freedom rights. Finally, one might consider an executive pardon or jury-nullification to be ex post "permission to break the law."
Yes P was standing in a hallway to which he had apparently been lawfully admitted Indeed. And what were the conditions imposed on P for that lawful admittance? If one of those was &quot;no photography&quot; then P would not have been lawfully on the premises once they started taking pictures; at that point, they would have been a trespasser. Similarly, if they were admitted under conditions of confidence. As a trespasser, the information they obtained would not have been obtained legitimately and would fall foul of protection on trade secrets. Of course, P's actions can be &quot;wrong&quot; without being unlawful.
You are not obliged to say anything to a police officer during a traffic stop, in fact you are generally better off staying silent. This is your Fifth Amendment right to silence. The only exception to this is that the officer could ask for your name and you are obliged to give it under Arizona Laws 13-2412, but the answer to that is language-independent and is usually already answered with your driver's license in a traffic stop. If you did choose to communicate only in German, this may have the effect of frustrating the officer's investigation but if you only make truthful statements in German it is unlikely to be obstruction of their investigation. Arizona Laws 13-2409 is I believe the relevant section (emphasis mine): A person who knowingly attempts by means of bribery, misrepresentation, intimidation or force or threats of force to obstruct, delay or prevent the communication of information or testimony relating to a violation of any criminal statute to a peace officer, magistrate, prosecutor or grand jury or who knowingly injures another in his person or property on account of the giving by the latter or by any other person of any such information or testimony to a peace officer, magistrate, prosecutor or grand jury is guilty of a class 5 felony, except that it is a class 3 felony if the person commits the offense with the intent to promote, further or assist a criminal street gang. In general, a law that required you to give answers to a police officer during an investigation in English if you understand English and have waived your right to silence would violate your First Amendment right to free speech (as it is in effect "forced speech"). However, you would need to be careful not to tell the police officer that you do not understand English if that is not true, as it could be misrepresentation. Police officer training likely includes instructions for detaining someone that cannot understand them and the police can detain you and wait for an interpreter to continue their investigation if they determine that is necessary. You may actually be shooting yourself in the foot by doing this, because the time it takes for them to get an interpreter likely extends the amount of time the detainment can last while remaining "reasonable," so you may be waiting by the side of the road longer than you would have if you had simply told the officer that you were invoking your right to silence and followed the officer's instructions without speaking. As an aside, as more people are educated on their rights via the Internet and understand why they should always invoke their right to silence when detained, police officers will get more used to people they pull over immediately and politely telling them that they are going to invoke their right to silence. I doubt most police officers will hold it against you as long as you are otherwise cooperative and don't yell at them or berate them.
(Assuming the jurisdiction is the US.) Your question I was wondering whether there are any limitations on using photos of private individuals on websites. is the least of your potential problems. Photos of the public taken in public are mostly legal to use and publish, and you own the copyright on the photo, and generally don't need a model release. But your plan of posting the photo with accompanying information about (alleged) fraud: There's a fraud conducting business in my state and I want to create a website that warns others of his fraudulent practices. is potentially legally problematic. As phoog indicates in his comment, you need to be aware of defamation, both at the federal level and among states, as some have criminalized defamation (Wikipedia). Libel is the publication of provably false facts by one person about another person. For a full outline of defamation (libel and slander, and including private and public figures), see Libel and Slander | Nolo.com. What you want to do is publish "facts" about this alleged fraud on the website with a photo of the individual, linking the fraud allegations to them. That is potentially libelous. The facts of the fraud may be provably true, or they may be provably false; that remains to be seen. But the facts don't matter when considering what actions the person can take against you if you publish such information on your website. If this business and the individual(s) feel they are not committing fraud, they can sue you for libel in civil court, alleging that you have damaged their reputation and impacted their business by publishing those facts on your website with the photo identifying the person and their business. If they take legal action, and you can prove the business and the individual(s) are committing fraud with provable facts - hard evidence of fraud, such as legal documents and court judgments - than you should (no guarantees) be able to successfully defend yourself in a libel suit brought against you by that person. Even if the business and the individual(s) are aware of facts that prove their fraud, and know they will probably not prevail in court, they can still take you to court, and it will cost you whatever time and money it takes to defend yourself. My responses above concern what legal actions the alleged could take against you if you published the website with the photo and information about the alleged fraud. No one here is advising you to put up the website with the photo and the "facts" as you see them, even if you have hard proof of the facts of the fraud; you should find legal representation before taking any action with the website. And, no one here is advising you to open any legal action against the person; that's your choice in terms of determining your case and if you can show actual harm that was caused by the alleged fraud by the individual, and you should find legal representation before taking any action.
