The Fourth Amendment to the United States Constitution deals with warrant requirements. It is part of the Bill of Rights and was ratified by the states in 1791. The amendment prohibits unreasonable searches and seizures and sets requirements for issuing warrants. Warrants must be issued by a judge or magistrate, justified by probable cause, supported by oath or affirmation, and must particularly describe the place to be searched and the persons or things to be seized. The amendment's ultimate goal is to protect people's right to privacy and freedom from unreasonable government intrusions. While it does not guarantee protection from all searches and seizures, it ensures that those conducted are deemed reasonable under the law.

Requirements for issuing warrants
The Fourth Amendment to the United States Constitution sets out requirements for issuing warrants. It states that people have the right to be secure in their persons, houses, papers, and effects, and are thus protected from unreasonable searches and seizures.
The Fourth Amendment requires that warrants must be issued by a judge or magistrate, justified by probable cause, supported by oath or affirmation, and must particularly describe the place to be searched and the persons or things to be seized. This requirement places the judgement of an independent magistrate between law enforcement officers and the privacy of citizens.
The standards for probable cause differ for arrest and search warrants. For an arrest warrant, probable cause is present when a police officer has a reasonable belief in the guilt of a suspect based on facts and information prior to the arrest. A search warrant, on the other hand, requires probable cause that a search is justified, and a court-authorised magistrate will consider the totality of the circumstances to determine whether to issue the warrant.
The Fourth Amendment also deals with the issue of electronically stored information. Rule 41(e)(2)(A) of the Federal Rules of Criminal Procedure authorises police officers to search electronic storage media or copy electronically stored information with a search warrant.
While the Fourth Amendment provides protections against unreasonable searches and seizures, there are several exceptions. For example, warrantless seizures of abandoned property or properties in an open field do not violate the amendment, as it is not reasonable to expect a privacy right under these circumstances. Additionally, the Supreme Court has ruled that police may stop and frisk an individual if they have a reasonable suspicion that the person has been, is, or will soon be involved in criminal activity.

Exceptions to the warrant requirement
The Fourth Amendment (Amendment IV) to the United States Constitution prohibits unreasonable searches and seizures and sets out requirements for issuing warrants. However, there are several exceptions to the warrant requirement, including:
Consent Searches
Individuals with authority over a location or apparent authority over a location can give consent to a warrantless search if the consent is voluntary.
Motor Vehicle Searches
The inherent mobility of automobiles makes it impractical for officers to always obtain a warrant prior to a search. In addition, people have a lesser expectation of privacy in their vehicles. A warrantless search of a vehicle may be justified if an officer has probable cause to believe the vehicle contains contraband, controlled substances, or criminal evidence.
Evidence in Plain View
When executing a search warrant, an officer might be able to seize an item observed in plain view even if it is not specified in the warrant.
Exigent Circumstances
Officers can forgo obtaining a warrant in emergencies, such as when rendering aid to a person in need, ensuring public safety, or preserving evidence in immediate danger of being removed or destroyed.
Border Searches
Border searches do not require a warrant, probable cause, or any suspicion.
Search Incident to Arrest
After arresting an individual, officers can search the individual and the immediate area to ensure no weapons are within reach and no evidence can be destroyed.
Other Exceptions
Other exceptions to the warrant requirement include searches of abandoned property or properties in an open field, drug testing, national security, school searches, and searches of prisoners, parolees, and probationers.

Probable cause
The Fourth Amendment (Amendment IV) to the United States Constitution is part of the Bill of Rights. It protects people's right to privacy and freedom from unreasonable intrusions by the government. The Fourth Amendment prohibits unreasonable searches and seizures and sets requirements for issuing warrants.
The Fourth Amendment states that "no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized". The concept of "probable cause" is central to the meaning of the warrant clause.
The standards of probable cause differ for an arrest and a search. A warrantless arrest may be justified when there is probable cause and an urgent need to arrest. For example, a police officer may make a warrantless arrest if they have a probable belief that a suspect has either committed a crime or is a threat to public safety.
In some circumstances, a warrantless search or seizure may be justified by probable cause and exigent circumstances, such as imminent danger, imminent escape, or the imminent destruction of evidence.

Search and seizure
The Fourth Amendment (Amendment IV) to the United States Constitution deals with warrant requirements and protects against unreasonable searches and seizures. It states that the right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated. It sets out requirements for issuing warrants, including that they must be issued by a judge or magistrate, justified by probable cause, supported by oath or affirmation, and must particularly describe the place to be searched and the persons or things to be seized.
The Fourth Amendment was introduced in 1789 by James Madison, along with the other amendments in the Bill of Rights, in response to Anti-Federalist objections to the new Constitution. It was ratified by the states in 1791. The Amendment was proposed due to the Framers' experience with the English Crown's use of its power to search and seize people and property. The full enjoyment of the rights of personal security, personal liberty, and private property is protected by the Fourth Amendment.
The Amendment's case law deals with three main issues: what government activities are "searches" and "seizures", what constitutes probable cause to conduct searches and seizures, and how to address violations of Fourth Amendment rights. Early court decisions limited the amendment's scope to physical intrusion of property or persons, but with Katz v. United States (1967), the Supreme Court held that its protections extend to intrusions on the privacy of individuals as well as to physical locations. This means that individuals have a reasonable expectation of privacy under the Fourth Amendment, even when they have turned over information to third parties. For example, in Carpenter v. United States (2018), the Court ruled that individuals have a reasonable expectation of privacy regarding cell phone records, requiring law enforcement to obtain a search warrant before receiving CSLI records.
The exclusionary rule, established in Weeks v. United States (1914), is one way the Fourth Amendment is enforced. This rule holds that evidence obtained as a result of a Fourth Amendment violation is generally inadmissible at criminal trials. Evidence discovered as a later result of an illegal search may also be inadmissible as "fruit of the poisonous tree", unless it inevitably would have been discovered by legal means. The Court has also ruled that law enforcement must obtain a search warrant "whenever reasonably practicable", and that the test is whether the search itself was reasonable.
There are several exceptions to the warrant requirement, including consent searches, motor vehicle searches, evidence in plain view, exigent circumstances, border searches, and "stop-and-frisk" searches. In some circumstances, warrantless seizures of objects in plain view do not constitute seizures within the meaning of the Fourth Amendment. Additionally, a warrantless arrest may be justified where probable cause and urgent need are present prior to the arrest.

Privacy rights
The Fourth Amendment to the United States Constitution is part of the Bill of Rights and deals with warrant requirements and privacy rights. It was ratified on December 15, 1791, and was introduced in response to Anti-Federalist objections to the new Constitution.
The Fourth Amendment prohibits unreasonable searches and seizures and sets requirements for issuing warrants. Warrants must be issued by a judge or magistrate, justified by probable cause, supported by oath or affirmation, and must particularly describe the place to be searched and the persons or things to be seized.
The ultimate goal of this amendment is to protect people's right to privacy and freedom from unreasonable intrusions by the government. However, it does not guarantee protection from all searches and seizures, only those deemed unreasonable under the law. To claim a violation of Fourth Amendment rights, courts have required that the claimant prove they were the victim of an invasion of privacy.
The amendment has been interpreted and applied in various court cases, including:
- Katz v. United States (1967), where the Supreme Court held that the amendment's protections extend to intrusions on the privacy of individuals, not just physical locations.
- Carpenter v. United States (2018), where the Court ruled that individuals have a reasonable expectation of privacy under the Fourth Amendment regarding cell phone records, even though they voluntarily provided that information to cell phone companies.
- Smith, where the Court held that individuals have no "legitimate expectation of privacy" regarding the telephone numbers they dial as they knowingly provide that information to telephone companies.
- Spinelli v. United States (1969) and United States v. Harris (1971), where the defendant challenged the sufficiency of the evidence presented to constitute probable cause for a warrant.
- Silverthorne Lumber Co. v. United States (1920), where the Court determined that illegally seized and copied evidence was "tainted" and inadmissible in a legal trial.
- Nardone v. United States (1929), which ruled that evidence obtained through warrantless wiretaps was inadmissible in court proceedings.
