The Fourth Amendment to the U.S. Constitution protects citizens from unreasonable searches and seizures by the government. Generally, law enforcement officials must obtain a warrant before searching a person or their property. However, there are exceptions to this rule, and warrantless searches may be deemed reasonable in specific circumstances, such as when there is probable cause, exigent circumstances, or lawful arrests. In the context of non-citizens, warrantless searches have been a contentious issue, particularly at the border and in the realm of foreign intelligence surveillance. The USA PATRIOT Act and the President's inherent constitutional authority have been cited as justifications for warrantless searches in these contexts, but they remain subject to legal and ethical debates.

What You'll Learn
The Fourth Amendment
Warrantless searches, seizures, and arrests may be justified by exigent circumstances. For example, courts have considered the following circumstances as exigent: when officers are in hot pursuit of a fleeing suspect, or to prevent the destruction of evidence. In such situations, police officers may dispense with the Fourth Amendment's warrant requirement. The US Supreme Court has upheld brief, warrantless seizures at certain fixed roadside checkpoints. For example, it has upheld such searches aimed at intercepting drunk drivers and illegal border crossings.
There are several other circumstances in which law enforcement may conduct a warrantless search or seizure. These include:
- When they arrest someone on suspicion of committing a felony, and the arrest was made in a public place
- When they search someone in good faith, but a court later rules the warrant they had was invalid
- When the items are in plain view
- When they have consent to search
- When there are special law enforcement concerns, such as highway sobriety checkpoints or routine stops and searches at international borders
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. If the conduct challenged does not fall within the Fourth Amendment, the individual will not enjoy protection under the Fourth Amendment.
The Supreme Court's decisions concerning the Fourth Amendment are important in criminal law and procedure today. For example, the decisions have clarified the situations in which a warrantless search is legal, what constitutes a search, and what happens if the government conducts an illegal search and seizure.

Exigent circumstances
In the United States, the Fourth Amendment protects citizens from unreasonable searches and seizures by the government, including law enforcement officials. Generally, a warrant is required for searches and seizures, and a police officer must demonstrate probable cause and explain why they believe a search will yield evidence of criminal activity.
However, there are exceptions to the warrant requirement, and one of the key exceptions is "exigent circumstances". Exigent circumstances refer to situations where immediate action is necessary, and they can justify a warrantless search or seizure. The determination of exigent circumstances is based on the totality of the circumstances and involves both legal and factual considerations.
Some examples of exigent circumstances include:
- Providing emergency assistance to an occupant of a home or a person in need of aid
- Engaging in "hot pursuit" of a fleeing suspect, especially in cases of felonies
- Entering a burning building or a structure to prevent harm to people or property, or to stop the destruction of evidence
- Preventing the escape of a suspect, particularly when there is a probability that they will flee before a warrant can be obtained
- Stopping the removal or destruction of evidence, including situations where the suspect is aware that the police are investigating
It is important to note that the interpretation of exigent circumstances can vary depending on the specific context and the totality of the circumstances. While exigent circumstances can justify a warrantless search, law enforcement officers must still have probable cause to believe that a crime has been or is being committed, and their actions must be reasonable and necessary to address the exigent circumstances.

Lawful arrests
In the United States, the Fourth Amendment protects citizens from unreasonable searches and seizures by the government. This includes any searches conducted by city, state, or federal government agents. Generally, law enforcement must obtain a warrant or have probable cause to perform a valid search or seizure. However, there are exceptions to the warrant requirement.
The U.S. Supreme Court has ruled that some warrantless searches may be deemed reasonable and lawful under the Fourth Amendment. For example, during exigent circumstances, such as when there is a need to protect an individual in danger, or during lawful arrests. In the context of vehicles, law enforcement can also conduct inventory searches of impounded vehicles without a warrant, including the trunk's contents. Additionally, during a Terry stop, designed to protect officers from hidden weapons, law enforcement can seize weapons or contraband that is in plain view.
Warrantless arrests are permitted in certain situations as well. Police officers can make a warrantless arrest when they have probable cause to believe that a felony or certain misdemeanours have been committed, especially when the offence is committed in their presence. This is allowed in states like California and Washington, as well as in countries like the Philippines. Similarly, in India, Section 35 of the Bharatiya Nagarik Suraksha Sanhita of 2023 empowers police to arrest an individual without a warrant under certain circumstances, including when an officer personally witnesses the commission of a crime or when there is a reasonable suspicion to prevent further criminal activity.
While the Fourth Amendment sets out protections for citizens, there have been instances of warrantless searches and surveillance for foreign intelligence purposes. The President of the United States has been deemed to have inherent authority to conduct warrantless searches in the interest of national security, as seen in the investigations of the Church Committee during the Cold War and in the case of CIA spy Aldrich Ames.

Foreign intelligence
Section 702 of FISA, passed in 2008, allows intelligence agencies such as the FBI, CIA, NSA, and NCTC to collect international communications without a warrant, targeting non-US citizens outside the US. This has been justified as a necessary tool for national security and counterterrorism efforts. However, critics argue that it has led to widespread abuses and invasions of privacy, with Americans' communications being swept up in the surveillance.
The Fourth Amendment to the US Constitution protects Americans' privacy and requires the government to obtain a warrant before accessing their private information. Despite this, intelligence agencies have conducted hundreds of thousands of ""backdoor searches," accessing Americans' communications, including those of activists, journalists, and members of Congress, without a warrant. These searches have provoked bipartisan outrage and efforts to reform FISA and close the "backdoor search loophole."
The Government Surveillance Reform Act (GSRA) and the Protecting Liberty and Ending Warrantless Surveillance Act are two bipartisan bills introduced to address these issues. The GSRA would require a warrant for searching Americans' communications, strengthen judicial oversight, and prohibit the government from purchasing data it would normally need a warrant to obtain. The Protecting Liberty Act aims to close the backdoor search and data broker loopholes and strengthen judicial oversight to prevent warrantless surveillance.
While there are ongoing efforts to balance national security needs with protecting civil liberties, the issue of warrantless foreign intelligence surveillance remains a complex and evolving debate in the US.

Border control
The Fourth Amendment is part of the Bill of Rights and 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, 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 protections apply to citizens and non-citizens alike, and generally, law enforcement officials must obtain a warrant before searching a person or their property. However, there are exceptions to the warrant requirement, and warrantless searches may be deemed reasonable in specific circumstances. For example, warrantless searches may be permitted in cases of exigent circumstances, such as when officers have probable cause to believe that evidence will be destroyed or removed, or when officers' safety is at risk.
Additionally, law enforcement may conduct a warrantless search during a lawful arrest, and in certain administrative contexts, such as vehicle checkpoints and roadblocks, factory or inventory searches, and detention of travellers.
In the context of border control, the primary concern is the protection of the country from potential threats, and warrantless searches at ports of entry are conducted to prevent the entry of contraband or prohibited items. These searches are justified by the inherent authority of the government to protect its borders and are typically limited to the person and their belongings being searched.
It is important to note that while the Fourth Amendment provides protections against unreasonable searches and seizures, individuals also have the right to deny a search request if law enforcement does not have a valid warrant. However, if an individual voluntarily consents to a warrantless search, they waive their Fourth Amendment rights, and any evidence collected during the search may be used against them.

Frequently asked questions
Law enforcement officials are generally required to obtain a warrant before searching a person or their property. However, there are exceptions to this rule, and in some cases, warrantless searches may be deemed reasonable and lawful, regardless of citizenship status.
Exceptions to the warrant requirement include exigent circumstances, lawful arrests, and searches incident to a valid arrest. Law enforcement may also seize contraband that is in plain view or conduct a Terry stop to protect themselves from hidden weapons.
Exigent circumstances refer to situations where failing to conduct an immediate search would lead to the destruction or removal of evidence, place officers or the public at risk of harm, or allow suspects to flee.
Yes, law enforcement may conduct a warrantless search of a vehicle if they have probable cause to believe there is contraband inside. This is because the expectation of privacy is diminished when driving on a public road.
Regardless of citizenship status, individuals have the right to deny a search. If evidence is obtained illegally during a warrantless search, it may be deemed inadmissible in court, and a Bivens action can be filed against law enforcement officials for damages.
