How do I authenticate that a warrant and its bearers are authentic? Questions... How can I tell if the warrant is authentic and authorized by an authentic court? How can I identify that the persons approaching me with the warrant are indeed authorized law enforcement officers? Am I legally allowed to confirm the above before complying with the contents of the warrant? I live in Massachusetts.
Your attorney can help you answer those questions, if necessary. Generally, you cannot know for certain. Mass. criminal procedure rule 6 covers arrest warrants – the Superior court can issue an arrest warrant. That warrant must be "signed" by the issuing official, will have the name or other reasonable means of identifying the subject, and the offense charged. An electronic signature is a signature. If the arresting officer does not have the warrant at the time of arrest, the arrest may proceed anyhow, and if he has the warrant, he shall on request show it to the defendant as soon as possible. If the officer does not have the warrant on him, he shall inform the defendant that a warrant has been issued. There is no practical way to look at a warrant and determine that is is a real warrant as opposed to a fake document created by thugs. There is no statute under which a person can resist arrest until they are satisfied that the arrest is by a legitimate officer and that the document was properly issued by the court. If there was no proper warrant, the arrest will probably be found unlawful and you will be set free until a proper warrant is issued. It would be unlawful for thugs to take you (impersonating an officer is a crime), and that is as far as the law goes. Ch. 267 of Massachusetts General Laws lays out the law regarding warrants, and those laws focus on the conditions for legally issuing a warrant, not for convincing a person that a warrant, search or arrest is legitimate. You may certainly attempt to confirm that the warrant and officer are real, but you cannot resist the search or arrest if you are not satisfied.
Since you don't say which country you're in, it's likely that you're interested in United States law. You are probably in the clear here, though you're getting close enough to the edge of breaking the law that I wouldn't be confident about not being prosecuted and/or convicted. The relevant laws in this case appear to be 18 USC 471, 18 USC 472, and perhaps 18 USC 514. All three of them begin "Whoever, with the intent to defraud...". It's questionable whether creating counterfeit money as a burglar decoy counts as defrauding the burglar.
Try the phone or email contacts at Florida Department of Law Enforcement - Home. The state of Florida doesn't appear to maintain a statewide officer registry, but that department should be able to verify someone is or isn't a officer in conjunction with the police department closest to your location. If this neighbor is threatening or attempting to enforce the law while not showing ID that proves he/she is an officer, that's serious, and you should call the local police department. Talking about being a LEO while drinking beer at a BBQ is less serious, but still could be a third degree felony. See Statutes &amp; Constitution - Florida State Statutes: 843.08 False personation.—A person who falsely assumes or pretends to be a firefighter, sheriff, officer of the Florida Highway Patrol, officer of the Fish and Wildlife Conservation Commission, fire or arson investigator of the Department of Financial Services, officer of the Department of Financial Services, officer of the Department of Corrections, correctional probation officer, deputy sheriff, state attorney or assistant state attorney, statewide prosecutor or assistant statewide prosecutor, state attorney investigator, coroner, police officer, lottery special agent or lottery investigator, beverage enforcement agent, or watchman, or any member of the Florida Commission on Offender Review and any administrative aide or supervisor employed by the commission, or any personnel or representative of the Department of Law Enforcement, or a federal law enforcement officer as defined in s. 901.1505, and takes upon himself or herself to act as such, or to require any other person to aid or assist him or her in a matter pertaining to the duty of any such officer, commits a felony of the third degree,
There is a good amount of case law addressing this question going back two centuries. Legally, as soon as you are subject to "excessive force," you are allowed to defend yourself as you would against any assault, even if that force is being used in the course of an otherwise lawful arrest. Furthermore, in some states you are still allowed to resist unlawful arrest. Unfortunately, the matter is no longer as clear as it used to be. (There is a lot of material on this subject; just search for resisting unlawful arrest.) For example, police reflexively invoke a virtual safe harbor by shouting, "Stop resisting!" while battering arrest subjects. Video evidence has uncovered a plethora of examples in which this was done to subjects who were not only not resisting, but even later determined to have been incapable of resisting. If you intend to defend yourself against police, even when justified by law, you need to realize that the system is stacked against you. Police carry the means of escalating to lethal force. So, for example, if you are being beaten but you are potentially able to physically overpower and restrain an officer, you will likely then be met with baton blows or tasers. Since a baton is a deadly weapon, you would be (in theory) justified in shooting an officer attacking you with one. But as soon as any officer shouts "gun!" you will be shot, and most likely killed. Police seem to be given the benefit of the doubt by prosecutors and grand juries when they claim, "I feared for my life." You (even if you survive) will likely have any such claim subject to a full criminal trial. So even though you can legally defend yourself against excessive police force, these days you will almost certainly be unable to in practice.
As mentioned in a comment by @Dancrumb, the exact policies of each local police department will be different, and there are thousands of them. There is a relevant requirement at the Federal level according the Department of Justice, but it is not clear to me to what extent this applies to peers and not just supervisors: An officer who purposefully allows a fellow officer to violate a victim's Constitutional rights may be prosecuted for failure to intervene to stop the Constitutional violation. To prosecute such an officer, the government must show that the defendant officer was aware of the Constitutional violation, had an opportunity to intervene, and chose not to do so. This charge is often appropriate for supervisory officers who observe uses of excessive force without stopping them, or who actively encourage uses of excessive force but do not directly participate in them.
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.
Probably not until and unless the process server gets the correct address and actually serves you. Then the documents should explain the matter fully. If the person who was attempted to be served took note of the court involved, and told you what court it was, you could call the Clerk of the Court and inquire. Otherwise you would need to ask every possible court, which would take a great deal of time and effort. You have not been lawfully served (at least not in most US jurisdictions) until you have been served in person, or perhaps by mail, or by publication in a newspaper, or in some other way considered lawful in your jurisdiction, but serving a person at your old address is not likely to be valid service. (Valid methods differ from one jurisdiction to another, and in some situations differ by the kind of case involved.) If the person at your old address gave the server your new address, s/he will probably be along shortly. If a process server is given an address by the client (plaintiff), s/he may well go there first, and only do research later in case the first address is wrong. One need not worry about it until the papers are served, but it might be wise to read the legal ads in any nearby large newspapers for a few weeks, in case of service by publication. The papers should give the name of a court, and perhaps the name of a judge. You can call the clerk of the court and find out if the papers are legit. There may well be a docket no or case no or some other identifying umber, as well. This will help in verification. Docketed cases may be listed on a court web site. A comment asks is service by publication is still possible. It can be. According to the Michigan Court Rules Rule 2.106 (D): (D) Publication of Order; Mailing. If the court orders notice by publication, the defendant shall be notified of the action by (1) publishing a copy of the order once each week for 3 consecutive weeks, or for such further time as the court may require, in a newspaper in the county where the defendant resides, if known, and if not, in the county where the action is pending; and (2) sending a copy of the order to the defendant at his or her last known address by registered mail, return receipt requested, before the date of the last publication. If the plaintiff does not know the present or last known address of the defendant, and cannot ascertain it after diligent inquiry, mailing a copy of the order is not required. In addition, subrule (E) provides that: If the court orders notice by posting, the defendant shall be notified of the action by (1) posting a copy of the order in the courthouse and 2 or more other public places as the court may direct for 3 continuous weeks or for such further time as the court may require; and (2) sending a copy of the order to the defendant at his or her last known address by registered mail, return receipt requested, before the last week of posting. If the plaintiff does not know the present or last known address of the defendant, and cannot ascertain it after diligent inquiry, mailing a copy of the order is not required. The moving party is responsible for arranging for the mailing and proof of mailing. Thus if the plaintiff does not know and cannot determine the defendant's address, or has an incorrect address but thinks that it is correct, a service by publication (or even by posting) may be lawful, if the Judge so orders, without the defendant getting an individual copy of the documents by mail. This requires some unlikely events, but is possible.
I'm not aware of case law on point, other than Riley, which you mention (which doesn't mean that there isn't any - I'm not a specialist in this area). But, I think that the answer would be that you do have an expectation of privacy because the Riley holding that there was an expectation of privacy in a smart phone didn't really hinge in any meaningful way on the existence of a password. The linked summary of the Riley decision explains the court's reasoning as follows: Chief Justice John G. Roberts, Jr. wrote the opinion for the unanimous Court. The Court held that the warrantless search exception following an arrest exists for the purposes of protecting officer safety and preserving evidence, neither of which is at issue in the search of digital data. The digital data cannot be used as a weapon to harm an arresting officer, and police officers have the ability to preserve evidence while awaiting a warrant by disconnecting the phone from the network and placing the phone in a "Faraday bag." The Court characterized cell phones as minicomputers filled with massive amounts of private information, which distinguished them from the traditional items that can be seized from an arrestee's person, such as a wallet. The Court also held that information accessible via the phone but stored using "cloud computing" is not even "on the arrestee's person." Nonetheless, the Court held that some warrantless searches of cell phones might be permitted in an emergency: when the government's interests are so compelling that a search would be reasonable. Justice Samuel A. Alito, Jr. wrote an opinion concurring in part and concurring in the judgment in which he expressed doubt that the warrantless search exception following an arrest exists for the sole or primary purposes of protecting officer safety and preserving evidence. In light of the privacy interests at stake, however, he agreed that the majority's conclusion was the best solution. Justice Alito also suggested that the legislature enact laws that draw reasonable distinctions regarding when and what information within a phone can be reasonably searched following an arrest. The 4th Amendment expressly protects "papers" in your possession, which can't be password protected, and a smart phone file is analogous to a "paper" for 4th Amendment purposes. Your expectation of privacy in an unlocked smart phone flows from your exclusive possession of the phone as a piece of tangible personal property containing information, and not just from the password protection. In the same vein, I don't think that you would need to have a lock on a diary to have an expectation of privacy in it. This said, this is a cutting edge area of the law and password protection for a smart phone provides both more practical protection and potentially a less ambiguous cases of legal protection from search (since it brings you closer to the facts of Riley), and is therefore still a good idea.
