The Fourth Amendment protects the right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures. It also sets requirements for issuing warrants, stating 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.

Protecting personal privacy and dignity

The Fourth Amendment (Amendment IV) of the United States Constitution is part of the Bill of Rights. It was passed by Congress on September 25, 1789, and ratified on December 15, 1791. The Fourth Amendment protects the right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures. This means that people are protected from government intrusion into their privacy and dignity, whether accused of a crime or not.

The Fourth Amendment 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 standards of probable cause differ for an arrest and a search. For an arrest, the government must have probable cause to believe that a person has committed or is committing a crime, based on reasonably trustworthy information. For a search, the warrant must establish probable cause to believe that the search will uncover criminal activity or contraband.

The Fourth Amendment's protection against unreasonable searches and seizures extends beyond physical intrusion of property or persons. In Katz v. United States (1967), the Supreme Court held that the Fourth Amendment's protections also apply to intrusions on the privacy of individuals. This includes protection from unreasonable government searches of electronic communications and other forms of surveillance.

The Fourth Amendment does not guarantee protection from all searches and seizures, but only those done by the government and deemed unreasonable under the law. Courts have interpreted the Fourth Amendment to allow for investigatory stops, such as Terry stops or traffic stops, which are temporary questioning conducted in a manner necessary to fulfill the purpose of the stop. These stops are justified by an officer's reasonable suspicion and impose less of an infringement on personal liberty than an arrest.

The ultimate goal of the Fourth Amendment is to protect people's right to privacy and freedom from unreasonable intrusions by the government. This includes protection from unwarranted police intrusion into one's home, as held by the Supreme Court in Silverman v. United States (1961). The Fourth Amendment's protections were further extended to include "conversation" in Berger v. New York (1967), where the Supreme Court explained that the purpose of the probable cause requirement is to keep the state out of constitutionally protected areas until it has reason to believe that a crime has been or is being committed.

Requirements for issuing warrants

The Fourth Amendment (Amendment IV) of the United States Constitution is part of the Bill of Rights. It protects the right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures. This amendment places limitations and restrictions on the courts of the United States and federal officials in the exercise of their power and authority.

The Fourth Amendment also sets requirements for issuing warrants. Warrants must be issued by a judge or magistrate and must be justified by probable cause, which is when the facts and circumstances within their knowledge and of which they have reasonably trustworthy information that would lead a prudent person to believe a crime has been committed. Warrants must also be supported by an oath or affirmation and must particularly describe the place to be searched and the persons or things to be seized.

The amendment's requirements for warrants aim to protect personal privacy and dignity against unwarranted intrusion by the state. This was affirmed in Schmerber v. California (1966), where the Court held that "the security of one's privacy against arbitrary intrusion by the police is at the core of the Fourth Amendment."

The Fourth Amendment's protection can be waived if one voluntarily consents to, or does not object to, evidence collected during a warrantless search or seizure. Investigatory stops, such as Terry stops or traffic stops, are also considered warrantless seizures but are justified by a reasonable suspicion that a crime has been committed. These stops must be temporary and conducted in a manner necessary to fulfill their purpose.

The standards of probable cause differ for an arrest and a search. For an arrest, probable cause must exist before the arrest, and evidence obtained after the fact cannot be used to justify it. For a search, the warrant must establish probable cause to believe that the search will uncover criminal activity or contraband.

What constitutes a 'search'

The Fourth Amendment (Amendment IV) of the United States Constitution prohibits unreasonable searches and seizures and requires warrants to be issued based on probable cause. The question of what constitutes a "search" under the Fourth Amendment has been a matter of debate, with technological advancements expanding the government's ability to search and survey people.

A search occurs when there is an infringement on an expectation of privacy that society considers reasonable. For example, in Katz v. United States (1967), the Supreme Court held that the Fourth Amendment's protections extend beyond physical intrusion of property or persons to include intrusions on the privacy of individuals. This means that conversations and other forms of communication can be considered searches under the Fourth Amendment.

The standards of probable cause differ for an arrest and a search. In the case of an arrest, probable cause exists when the facts and circumstances lead to a reasonable belief that the arrested person committed or is committing a crime. For a search, the warrant must establish probable cause to believe that the search will uncover criminal activity or contraband.

The Fourth Amendment also applies to searches conducted by law enforcement officers during traffic stops, at international borders, and in schools. Officers may conduct a pat-down of the driver and passengers during a lawful traffic stop, and a narcotics detection dog may be used without reasonable suspicion. At international borders, routine stops and searches may be conducted by officers. In the case of schools, while the Fourth Amendment applies, school officials do not need to obtain a warrant to search a student; instead, the search must be reasonable under the circumstances.

In conclusion, a "search" under the Fourth Amendment occurs when there is an infringement on an individual's reasonable expectation of privacy. This includes not only physical intrusions but also other forms of surveillance and communication. The determination of whether a search is reasonable depends on balancing the individual's Fourth Amendment rights with legitimate government interests, such as public safety.

What constitutes 'probable cause'

The Fourth Amendment to the US Constitution protects citizens from ""unreasonable searches and seizures", as well as warrants issued "without probable cause". Probable cause is a flexible concept and a requirement that must usually be met before police make an arrest, conduct a search, or receive a warrant. It is stronger than reasonable suspicion but weaker than the requirement of evidence to secure a criminal conviction.

Probable cause is determined by the totality of the circumstances, which means everything that the arresting officers know or reasonably believe at the time of the arrest, including information from victims or witnesses. It is defined as when a reasonable person would believe that a crime was in the process of being committed, had been committed, or was going to be committed. This is based on the factual and practical considerations of everyday life on which reasonable and prudent men, not legal technicians, act.

For example, in the case of Maryland v. Pringle, an officer was permitted to arrest three individuals in a vehicle where marijuana was discovered. The court reasoned that even though the officers did not have evidence that any one of the three occupants was responsible for the drugs, probable cause existed as to all of them because co-occupants of a vehicle are often engaged in a common enterprise and all three denied knowing anything about the drugs.

In another case, United States v. Place, a trained dog alerted DEA agents to the smell of drugs in Place's luggage at LaGuardia Airport in New York City. The Supreme Court ruled that dogs alerting their officers provides enough probable cause for the officer to obtain a warrant.

Probable cause can also be established by an affidavit by a law enforcement officer asserting their belief that a crime was being committed, based on their own observations and those of fellow investigators, along with a substantial amount of personal observation supporting the stated belief.

How to address violations

The Fourth Amendment (Amendment IV) to the United States Constitution is part of the Bill of Rights. It protects the right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures. The Fourth Amendment also sets requirements for issuing warrants, stating 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.

• The exclusionary rule, established in Weeks v. United States (1914), holds that evidence obtained as a result of a Fourth Amendment violation is generally inadmissible at criminal trials. Evidence discovered as an indirect result of an illegal search may also be inadmissible under the "fruit of the poisonous tree" doctrine. However, there is an exception if the evidence would have inevitably been discovered by legal means.
• Court rulings have defined "search" and "seizure" in the context of the Fourth Amendment. According to United States v. Jacobsen, a "search" occurs when an expectation of privacy that society considers reasonable is infringed, while a "seizure of property" occurs when there is meaningful interference with an individual's possessory interests in that property.
• The Supreme Court has held that the core purpose of the Fourth Amendment is to protect personal privacy and dignity against unwarranted intrusion by the state. In Katz v. United States (1967), the Court extended the amendment's protections beyond physical locations to include intrusions on the privacy of individuals.
• In Berger v. New York (1967), the Supreme Court clarified that the Fourth Amendment's protections include "conversation" and are not limited to "persons, houses, papers, and effects".
• The Fourth Amendment applies to state and local governments through the Due Process Clause of the Fourteenth Amendment, as held in Mapp v. Ohio (1961).
• The amendment's protections do not guarantee protection from all searches and seizures, but only those deemed unreasonable under the law. The determination of reasonableness involves balancing the intrusion on an individual's Fourth Amendment rights with legitimate government interests, such as public safety.
