What You'll Learn
The right to privacy
The Fourth Amendment to the US Constitution, ratified on December 15, 1791, is part of the Bill of Rights, which comprises the first ten amendments. The Fourth Amendment guarantees "the right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures". This amendment was created in response to increasing infringements on privacy in the colonies and in England.
In England, "general warrants" allowed royal officials to search the belongings of individuals without cause, except for the suspicion that they were political enemies. Meanwhile, in the colonies, "writs of assistance" authorised officials to conduct warrantless searches for untaxed items. The Fourth Amendment thus ensures that warrants shall only be issued upon probable cause, supported by an oath or affirmation, and with a particular description of the place to be searched and the persons or things to be seized.
The Fourth Amendment has been central to several 20th-century Supreme Court decisions. In Silverthorne Lumber Co. v. United States (1920), the Court ruled that illegally seized evidence was "tainted" and inadmissible in court. Similarly, in Nardone v. United States (1939), the Court held that evidence obtained through warrantless wiretaps was inadmissible.
The 20th and 21st centuries have witnessed debates over the Fourth Amendment's longevity, particularly regarding mass surveillance programs during the Cold War and the War on Terror. Supporters of these programs argue that they are justified by the "probable cause" of deterring crime and terrorism. Critics, however, contend that these programs are too invasive and often retrieve data irrelevant to court trials.
The Fourth Amendment does not protect against all searches and seizures, but only those conducted by the government and deemed unreasonable under the law. Courts have required claimants to prove that their expectation of privacy was arbitrarily violated to establish a violation of their Fourth Amendment rights.

Search and seizure laws
The Fourth Amendment to the US Constitution protects people against unreasonable searches and seizures. Search and seizure laws are an important aspect of the Fourth Amendment, which guarantees the right of the people to be secure in their persons, houses, papers, and effects. This means that law enforcement officers cannot simply search or seize a person, their home, or their property without a valid warrant or probable cause.
The Fourth Amendment sets out the requirements for a warrant to be considered valid. Firstly, it must be supported by probable cause, which means that there must be reasonable grounds to believe that a crime has been or will be committed. Secondly, the warrant must be supported by an oath or affirmation, which is a sworn statement by the officer requesting the warrant that the information provided is true and correct. Lastly, the warrant must specifically describe the place to be searched and the persons or things to be seized.
In certain situations, law enforcement officers are allowed to conduct limited searches or seizures without a warrant. For example, they may perform a "stop and frisk" if they reasonably suspect that a person may be armed and dangerous. During a "stop and frisk", officers can pat down a person's outer clothing for weapons. However, they must have reasonable suspicion that the person has committed or is about to commit a crime in order to temporarily detain them.
Courts have also considered the application of the Fourth Amendment to digital information and technology. In Riley v. California (2014), the Supreme Court held that police generally may not search digital information on a cell phone seized from an individual who has been arrested without a warrant. Similarly, in Collins v. Virginia (2018), the Court found that the government's acquisition of an individual's cell-site records constituted a Fourth Amendment search. These cases illustrate how the Fourth Amendment continues to evolve and adapt to new technologies and situations.
The exclusionary rule is another important aspect of search and seizure laws. It states that evidence obtained in violation of the Fourth Amendment may be excluded from trial. However, there are exceptions to this rule. For example, in Arizona v. Evans (1995), the Supreme Court held that the exclusionary rule does not apply when the violation resulted from clerical errors made by court employees.

Warrants and probable cause
The Fourth Amendment of the U.S. Constitution protects the right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures. It 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".
This provision aims to protect people's right to privacy and freedom from unreasonable government intrusions. It does not, however, guarantee protection from all searches and seizures, but only those conducted by the government and deemed unreasonable under the law. To claim a violation of Fourth Amendment rights as the basis for suppressing relevant evidence, a claimant must prove that their privacy was invaded.
Probable cause is a fundamental concept in Fourth Amendment jurisprudence. It is the threshold for law enforcement to obtain warrants, conduct searches, and make arrests. Police and judges use probable cause to determine if there is enough reason to believe that there are facts that would make a reasonable person think a crime has occurred or that evidence will be found. For example, in United States v. Ventresca, an affidavit by a law enforcement officer asserting his belief that an illegal distillery was being operated in a certain place was held to be sufficient to constitute probable cause.
Probable cause is established through facts and evidence and is stronger than a reasonable suspicion, requiring more than mere hunches. It can be distinguished from reasonable suspicion, which allows an officer to stop and briefly question or frisk a person. For instance, a traffic stop requires a reasonable suspicion of a traffic violation or criminal activity, but a prolonged detention or search requires probable cause.
The protection under the Fourth Amendment can be waived if one voluntarily consents to, or does not object to, evidence collected during a warrantless search or seizure. Courts must determine what constitutes a search or seizure under the Fourth Amendment. An arrest warrant is preferred but not required to make a lawful arrest, and a warrantless arrest may be justified where probable cause and urgent need are present.

Surveillance and privacy
The Fourth Amendment to the United States Constitution, ratified on December 15, 1791, is a part of the Bill of Rights and deals with the issue of surveillance and privacy. It protects the American people from unreasonable searches and seizures, stating 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, and 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 Fourth Amendment sets out requirements for issuing warrants, including that they must be issued by a judge or magistrate, justified by probable cause, and supported by an oath or affirmation. This amendment was created in response to increasing infringements on privacy in the colonies and England, where "general warrants" and "writs of assistance" allowed officials to conduct warrantless searches.
The Fourth Amendment has been invoked in modern times, particularly following the 9/11 terrorist attacks and the War on Terror, which led to increased mass surveillance. Supporters of these measures argue that they are necessary for deterring crime and terrorism, while critics argue that they are too invasive and widespread to be justified under the Fourth Amendment.
The Fourth Amendment has also been the subject of several Supreme Court cases, including Katz v. United States (1967), which held that the amendment's protections extend beyond physical intrusion of property or persons to include intrusions on the privacy of individuals. Other cases, such as Silverthorne Lumber Co. v. United States (1920) and Nardone v. United States (1939), ruled that evidence obtained illegally or through warrantless wiretaps was inadmissible in court.

Evidence and the exclusionary rule
The Fourth Amendment of the U.S. Constitution, ratified on December 15, 1791, protects people against unreasonable searches and seizures. It states that no warrants shall be issued without probable cause, supported by an oath or affirmation, and that the place to be searched and the persons or things to be seized must be described in detail.
The exclusionary rule is a court-created remedy and deterrent that prevents the government from using most evidence gathered in violation of the Fourth Amendment. This rule was established due to the ineffectiveness of the warrant procedure in preventing illegal searches and seizures. It acts as a symbol of the justice system's commitment to protecting citizens' rights. The exclusionary rule is not an independent constitutional right, but it helps enforce the Fourth Amendment by deterring law enforcement from conducting unreasonable searches and seizures.
The exclusionary rule applies to evidence obtained through unreasonable searches or seizures in violation of the Fourth Amendment, as outlined in Mapp v. Ohio. It also applies to improperly elicited self-incriminatory statements that violate the Fifth Amendment, as per Miranda v. Arizona. Additionally, the rule covers situations where the government violates the defendant's Sixth Amendment right to counsel. However, it does not apply in civil cases, including deportation hearings, as mentioned in INS v. Lopez-Mendoza.
The exclusionary rule also applies to "fruit of the poisonous tree," which refers to evidence that was initially obtained illegally and later used to uncover new evidence. In some cases, the relationship between the challenged evidence and the unconstitutional conduct may be too remote, and the evidence may be deemed admissible, as seen in Utah v. Strieff. The Supreme Court has also recognized exceptions to the exclusionary rule, such as in Harris v. New York, where tainted evidence can be used to "impeach" or challenge the credibility of a defendant's testimony, but not to prove guilt.
Opponents of the exclusionary rule argue that it is not an effective deterrent for police misconduct and that civil remedies should be prioritized. They suggest that effective civil remedies against the government for unlawful searches or seizures could potentially narrow the scope of the exclusionary rule. However, supporters of the rule emphasize its importance in depriving the government of the benefits of illegal actions and protecting citizens' rights.

Frequently asked questions
The Fourth Amendment to the United States Constitution is part of the Bill of Rights. It 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 historical context of the Fourth Amendment is perceived as being in stark contrast to the modern world in which it has been invoked. In the late 18th and early 19th centuries, policing in most countries, including the United States, was largely conducted by citizens during nighttime patrols. As American cities grew in size and population, there were calls for the creation of full-time police officers.
