What would happen if there is an attempt by police to deceive a judge to get a warrant? Would I be correct in saying that police have a duty to fairly represent the facts to a judge when they attempt to get a warrant to search premises? Is there some sort of oversight in regard to how warrants are issued? Or is the oversight having your lawyer contest the validity of the search at your trial? If a judge thinks the police are, either through neglect or incompetence, withholding information that would keep a judge from issuing a warrant what would happen then? Is this grounds for a policeperson losing his or her job or can a judge just then choose not to issue any further warrants with that department, making there job just that bit harder?
You are correct. A judge may only issue a warrant when it is supported by an affidavit, in which the officer seeking the warrant swears under oath to the facts supporting the warrant. Lying on the affidavit would constitute perjury. But judges very frequently just rubber-stamp the warrants without meaningfully reviewing the affidavits, so the primary form of oversight would be the defendant's Fourth Amendment challenge asserting that the warrant wasn't supported by probable cause. If a judge does review the warrant application and finds the officer's statements not to be credible, he can refuse to sign the warrant, and he is free to also carry that credibility determination to subsequent warrants sought by the same officer or other officers in his department.
So, lets say for argument's sake the search is illegal (we'll discuss scenario later). Is the murder weapon inadmissible? No. Evidence seized in an illegal search is inadmissible for use in court, as to allow it would reward the state for breaking the law. At time of arrest it's still evidence and depending on what other evidence comes out might not be inadmissible (More on this later). If the knife is the only thing linking the driver to the murder, then it's inadmissible. What would happen to the driver, who was most likely the murderer? At this stage, the driver might be arrested and charged... inadmissibility is a matter for pre-trial motions, which takes place after the cop made the search. Whether the guy is a murder or not, he is a suspect who has been accused. Can the police arrest him, and investigate him with the hope of finding other evidence that would be enough to sentence him for the murder, despite the inadmissibility of the actual weapon? This all takes place before the inadmissibility of evidence is declared, so they certainly could investigate the guy, cuff him, read him his rights, book him, Danno, and put him in jail to help build their case. HOWEVER, if the knife is the only thing linking the man to the crime, then all of this becomes what's called &quot;Fruit of the Poisonous Tree&quot;. Because the knife was used as the sole evidence to secure search warrants against the suspect, and should the knife become inadmissible, anything that resulted from the execution of the warrants is itself inadmissible. is the murderer in practice immune from being charged for this case, since the weapon cannot be tied to him? Not entirely. Rarely is a murder weapon needed to secure a conviction. Not only that, but while the search is illegal, there is an exception called &quot;Inevitable Discovery&quot; which holds that evidence seized illegally initially may still be admissible if the cops can show that the legally obtained evidence would have led to the knife. Suppose they had CCTV footage and captured the man entering the area of the scene and found out he had a connection to the victim, and got a warrant that would have included his car... that would mean the knife is admissible even if the search was illegal. If the weapon is considered inadmissible, is it returned to the suspect? If yes, would it also be returned even if it is of a type that the suspect is not legally allowed to own? Yes to both, though when it would be returned is subject to possible use in other investigations. Additionally, while I don't know of any knife ban laws in the U.S., there are examples of contraband seized by arrest for a different offense was not returned when the initial offense was overturned on appeal, meaning the contraband evidence was no longer validly seized and thus that half of the case was overturned... but the defendant wasn't returned his drugs. Is the weapon permanently inadmissible for all future, or could it be used in a later court proceeding? No. I'm starting to suspect I know the TV show and episode that inspired this question, but the search violated suspect 1's rights and thus was inadmissible for his trial. However, if a second suspect was discovered as the evidence was developed, and the investigation lead to the knife (say... suspect 2 had access to suspect 1's car... like say... through his job at a car wash that suspect 1 was patronizing... and planted the knife in suspect 1's car to frame him) then the knife is admissible because of inevitable discovery rule. Now, the TV Show I alluded too, and you'll forgive me as it's been a while, the events were that the cop pulled over suspect 1 for a valid reason (busted tail light, intentionally done by suspect 2 to get attention) and saw the knife on the backseat of the car, which is not a violation of search and seizure rules. The bloody knife was in plain view and gave probable cause to arrest and search the entirety of the car. If you leave evidence in a place where the officer can see it, they can seize it in a car at least. Places like the glove box, under the seats, or the trunk would properly hide it and not allow the officer to search the car, but through the windows is just fine.
Are you required to comply with a police officer's order to put your baby down in an uncertain situation and allow yourself to be handcuffed? Of course. If holding a baby could immunize people against arrest, every criminal would have a baby around whenever possible. Similarly, suppose an officer legitimately fears for his or her life or safety, or the lives or safety of others, on the basis of a suspicion that someone carrying a baby is about to produce a weapon and use it against someone. Courts, at least in the US, give wide and explicit deference to police officers in stressful situations like that, and they recognize that even if, in hindsight, it is perfectly clear that there was no danger, the officer must be allowed the leeway to act on his or her suspicions in case they are correct. The officer will of course have some obligations to ensure the welfare of the child after separation from the adult, but the only immediate recourse the adult has is to appeal to the officer directly, or perhaps the officer's supervisor if he or she is available. Any other enforcement of the officer's obligation will have to take place in the courts after the fact.
The IRS Criminal Investigation division is typically going to be the arresting agency, assuming that (1) the offense is treated as a criminal matter; (2) a warrant is actually issued; and (3) anyone actually sets out specifically to serve the warrant. It is usually the case, though, that the violation is handled as a civil matter. When it is treated as a criminal violation, the defendant and the Service often reach an agreement that eliminates the need for an arrest. If there is a warrant, though, any police agency could theoretically make the arrest if they happened across the defendant. But if it's a time-sensitive investigation -- if the defendant is expected to flee or destroy evidence, for example -- it's a safer bet that you'll see an actual warrant execution. In that case, you would have CI taking the lead, perhaps with assistance from other agencies.
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.
If no one objects to a leading question, then the judge does nothing. A judge does not generally pro-actively police the rules of evidence at trial. Also, there are circumstances when a judge has discretion to allow a leading question even when it wouldn't ordinarily be allowed to move the trial along on largely undisputed points or to allow in inarticulate witness to testify. The exception to judicial passivity in the absence of an objection at trial is "plain error" that is not "harmless error", which a judge has a duty to prevent or address even if no objection is raised by a party. But, offering a leading question when one is not allowed by the rules of evidence almost never constitutes plain error, and would almost always be considered "harmless error" even if it was objected to and the judge ruled incorrectly, unless the use of improper leading questions was pervasive and there was a contemporaneous objection by counsel. For example, allowing a prospective juror to serve as a juror, despite that juror saying in the jury selection process that he can't be impartial because the defendant committed adultery with his spouse, because neither the prosecution or the defense attorney moves to strike the juror for cause, rather than striking that juror for cause of the court's own accord, is the kind of conduct that would often be considered "plain error" that is not "harmless error."
Generally, a local county judge’s decision is not binding on the judgement of another judge unless it is that of an appellate division. The law of the case principle could be referred to as an argument if it would have been decided by another judge in the same case (some courtships work on a rotary basis with different judges sitting over a single case). This would mean that the court would give greater deference to that decision; however, applying the principle is a matter of administrative preference to save resources of the court. Whether or not the other judge would reconsider the matter would be within their discretion absent binding authority to the contrary as a “law of the case” is not binding. In fact, even if it would have been the same judge with the exact same facts deciding the matter in a final judgement, there wouldn’t be much to do. One could argue that deciding differently is a violation of the Fourteenth Amendment which, if the judge fails to explain the different decision on the exact same facts may have a reasonable probability to get overturned provided the unconstitutionality finding was correct in the first place. If the matter was, in fact, unconstitutional, appeals may overturn a contrary judgement if the issue is brought up in the lower court and enters the court record. It may have some weight still to cite the decision of the other judge as the argument may be given more weight than if merely delivered as the argument of counsel.
You are allowed to ask the police whatever questions you like. There is an upper limit that you can't refuse to obey a lawful order on the premise that you want to ask a bunch of questions, but they don't seem to have ordered you to do anything, so you can ask away. They have no obligation to tell you anything or to be truthful, except for certain questions like "am I free to go" when you want to leave and are testing whether you are under arrest. Even then they don't have to answer your questions right away. The police can therefore ignore you, especially if you are asking curiosity questions. It might be that they are restricted from giving information in certain circumstances (pertaining to the privacy of others). If there is an issue of legitimate concern (e.g. Little Billy has been beating up on cats again) and you feel that you need to know this, then you can request the police record on the matter. Certain information will probably be redacted under state law, but you could get a report that states that some [redacted] juvenile was beating up on animals. The Florida records law is one of the first in he nation, dating back to 1909. You can read this, to see if you think the circumstances match one of the exemptions, though all you have to do is make the request and be told that the record is exempt, then you will have some idea what was going on.
