Do police officers in the USA have to carry the law/code book? I have seen several videos recently where police officers in the USA approach or detain someone, and then open a binder with laws/codes of the area and show the people what they violated. Question is, do police officers usually carry such binder? If so, what is it called? Also, can a person call into doubt the officers actions by demanding to review that binder?
It is possible that there is such a booklet in some jurisdiction, and that local police are required to carry that booklet and show it to persons on demand. This link (apparently) publicly provides the police manual for the city of Seattle, except it is 5 years and a major lawsuit out of date. No provision seems to exist that requires showing authority to detain, when requested. There is no general requirement for all police and all laws, in the US, and the full set of state, county and city codes would be impractical to lug around. If required by law to carry and display some such document, then by law a person can demand to see a police officer's authority to detain. Even without such a law, you have a First Amendment right to challenge the detention, but that does not also enable you to resist arrest. A detention is not invalidated by the fact that the detainee is unsatisfied that the detention is legal.
In Massachusetts where I live, here are the general guidelines: In re G.L. c. 268, § 32B(b). A person can be charged with resisting arrest only when the officer is acting under the color of his official position (meaning he is on duty and acting according to those duties). The Commonwealth must also prove that the defendant knew that the person seeking to make the arrest was a “police officer.” The Commonwealth may do so by proving that the officer was in uniform or, if not in uniform, identified himself (herself) by exhibiting his (her) credentials as a police officer while attempting to make the arrest. Such credentials would include such things as a badge, insignia, identification card, police radio, or other police equipment such as a clearly identified police vehicle. Thus, in Massachusetts according to usual legal interpretation: (1) The officer must be on duty and acting in an official capacity. (2) The officer must be provably known to be a police officer by some means to the person charged. Resisting arrest must be ancillary to some other charge. You cannot just be charged with "resisting arrest" unless you are actually being arrested on some other charge (or interfering with someone else being arrested). So, as far as a search is concerned, even if the resisting arrest charge were thrown out, the real question would be why was the person being arrested in the first place? That would determine the admitability of the evidence.
Although the USA don't like it, there's a department called INTERPOL which is composed by about 150 countries. When a crime is committed and you need to involve another country to solve it, the sovereignty of each County prevents a police officer from one country acting upon another country. That's when the INTERPOL comes in. They usually requests the police from that country to act up. A judge from that country will grant their local police access to the data to be delivered to the country that requested it. Can the police get a search warrant for data 'in the cloud'? Yes. If the servers are located within the boundaries of your own country, it's a normal procedure. But like the above answer states, it's easier to subpoena the records than to execute a search warrant. In a subpoena, the company itself is bound to provide everything the police asks. Can the police get a search warrant for such third party systems? Yes. If there's enough probable cause, the investigation can lead to allow the police to try and discover files that are held by servers that store the cloud data. But if the servers are located outside the country and the company does not have any office opened in the country, a search warrant won't have validity in another jurisdiction and the police can't act without breaking the sovereignty principle. That's where the INTERPOL services are handy. The department is built in the principle of polices from different countries helping each other. The downside is that it's too bureaucratic and it takes a lot of time. For instance if he has a virtual machine hosted by Amazon, would they serve the warrant on Amazon, or on the suspect? Like mentioned by @Viktor, if the company has an office within the bounds of your country, it's easier to subpoena the records because that way the company will filter and provide only the data linked to the suspect being investigated. That is, the subpoena will have both the name of the company (Amazon) and the name of the Suspect, so the company can provide only the necessary files. Update If the police lack sufficient evidence for a search warrant, but an interpol country was, for some reason, willing to work with the police to collect and provide that information would they be able to use it even if they wouldn't have been able to subpoena a US country? Hypothetically speaking, I see your follow-up as a company that do have a local office and the Federal Police was turned down by a judge on a warrant/subpoena. In that case, there's no reason for another's country police to act on their own country. The suspect is a foreign suspect, the crime is a foreign crime and the police has no reason to work on it. But for the sake of argument, let's say that the local police was turned down by a judge for lack of evidence or something and the suspect has been investigated by a foreign country or whatever. If the information that the local police desires to obtain is available through the INTERPOL, it's most likely to be accepted since it's a data stored by an international police department. In your scenario, the foreign police was granted a legal right to search and collected the data for legal purpose. Maybe they can't use it in their own country, but since they followed a safe chain of custody and provided the information to the INTERPOL, that information has legal validity and it is not fruit of the poisonous tree if the chain of custody was maintained.
The powers given to law enforcement professionals will be detailed in the relevant law that establishes them. I would suspect that the decision to cordon off an area would fall within the purview of the officer on the scene; the idea that a police officer would need to seek permission before cordoning off a motor vehicle accident or chemical spill is unworkable. I would also suspect that other emergency personnel (e.g. ambulance and fire-fighters) would have similar powers. However, such cordoning off would be a temporary measure and if it was maintained for an unreasonable period it would be open to challenge through an administrative or judicial process. If the police decided that a feature was a permanent hazard then they could seek a court order on the owner of the property to provide some measure to adequately protect the public, by either removing the hazard or providing some permanent barrier, under whatever laws seemed most appropriate.
There are multiple police forces in the US: city, county, state and national, and each is responsible to a relevant executive. Typical &quot;police&quot; are city police, who are responsible to a chief of police, who is appointed at the municipal level. Counties usually have an elected sheriff, and a set of deputies; at the state level, they are usually called state troopers. The typical protocol is that decisions are made at the lowest applicable level, so Seattle police enforce or refuse to enforce laws within Seattle, and King County police enforce or not in remaining unincorporated locations in the county. Individual city officers do not then decide to ignore the chief of police and instead follow orders from the county sheriff or the governor. However, each state grants vast powers to their governor, so it is possible that in the case of a state of emergency, the governor can take command of all law enforcement in the state. Governors &quot;can't&quot; deploy police to oppose federal law enforcement in a shoot-out, except that they might actually do so on some theory that federal law enforcement officers are violating the law. In general, you are not immune to arrest for illegal acts just because you are a law enforcement officer. The governor of Washington could easily (in the legal sense) declare an emergency and order state troopers to prevent federal officers from effecting arrests. Of course, resolving these disputes in court is another option.
Let's say you leave fake drugs in someone's yard. Eg, you expect the police to be dumb enough to believe it and arrest the other person Obstructing a public officer, specifically "deliberately hindering a public officer from carrying out official duties". Trespassing.
This is currently untested but the U.S. Supreme Court did leave the door open to allow someone to plead the 5th amendment in order to hide their identity. In Hiibel v. Nevada the U.S. Supreme Court held that the petitioner did not have a 5th amendment right to withhold his name from a questioning police officer. The Supreme Court held that Mr. Hiibel could be arrested for failing to identify himself because Nevada's statute requiring identification was narrowly tailored and was not vague. The police officer who stopped Mr. Hiibel had reasonable suspicion that a crime had occurred and Mr. Hiibel could have satisfied Nevada's statute by simply stating his name; there was no requirement to turn over any papers or other documentation. The final paragraph of the opinion speaks of the importance of the narrow scope of the disclosure requirement and then goes on and states: ...Answering a request to disclose a name is likely to be so insignificant in the scheme of things as to be incriminating only in unusual circumstances...Even witnesses who plan to invoke the Fifth Amendment privilege answer when their names are called to take the stand. Still, a case may arise where there is a substantial allegation that furnishing identity at the time of a stop would have given the police a link in the chain of evidence needed to convict the individual of a separate offense. In that case, the court can then consider whether the privilege applies, and, if the Fifth Amendment has been violated, what remedy must follow. We do not resolve those questions here. While the court is leaving unanswered the question of whether there are circumstances where one may refuse to identify themselves, they are making it quite clear that such a situation would be very different than the case decided in Hiibel. There is a strong hint that they would uphold Fifth Amendment privilege in the situation you posit.
When you refer to customs, that necessarily denotes travel to a foreign county, such that each county will have their own laws, rules, and regulations that govern these issues. It is more than likely that if you refuse to answer the questions of customs officials in ANY country, you will be denied admittance. The same is true if you refuse or balk at being searched (personally or your possessions), and keep in mind that this is without reasonable suspicion or probable cause. The best thing to do is to answer the questions honestly and accurately, but also as narrowly as possible to completely answer. Trying to argue with them will only send up red flags and you will be there longer. Remember it is a privilege, not a right, to enter a sovereign nation of which you are not a citizen. For example, in the U.S., customs reserves the right to detain for questioning, search you, your car, your children, your bags, packages, purse/wallet, or any other travel item with full legal authority to do sol they can even examine your electronics (content and hardware). You place your stuff on the exam station and open it. (After the exam is completed, you will be asked to repack and close the baggage.) If you are unhappy with the way you are being treated, you do have the right to ask to speak to a CBP supervisor, but I cannot see anything good coming of it, unless they were super rude without provocation or broke something of value. The authority to delay and speak with travelers derives from the United States Code (section citations below) enables CBP to prevent the entry of persons who are inadmissible under the Immigration and Nationality Act, and to prevent the smuggling of merchandise, including narcotics and other contraband items, into the United States. Speaking with travelers and examining merchandise coming into or leaving the United States is just one of the mechanisms used to identify illegal or prohibited items, and to determine whether or not someone is trying to enter the U.S. for unlawful or fraudulent purposes. Unless exempt by diplomatic status, all travelers entering the United States, including U.S. citizens, are subjected to routine Customs examinations. At times, people make the mistake of thinking their civil rights are being violated by being asked questions about their trip, personal background and history, etc. That is not the case. Supreme Court decisions have upheld the doctrine that CBP's search authority is unique and does not violate the fourth amendment's protection against unreasonable searches and seizures. U.S. Customs website has a detailed Q&amp;A section. Most modern countries do as well.
