What You'll Learn

The Fourth Amendment
The exclusionary rule is one way the Fourth Amendment is enforced. This rule, established in Weeks v. United States (1914), holds that evidence obtained through a violation of the Fourth Amendment is generally inadmissible in criminal trials. Additionally, evidence discovered as an indirect result of an illegal search may also be excluded as "fruit of the poisonous tree," unless it inevitably would have been found through legal means.

Search warrants
The Fourth Amendment to the United States Constitution deals with search and seizure. It is part of the Bill of Rights and prohibits 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 warrant 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 amendment puts limitations on the courts and federal officials in the exercise of their power, ensuring that people are protected from unlawful searches and seizures, regardless of whether they are accused of a crime or not.
Warrants are typically executed during the day, between 6:00 a.m. and 10:00 p.m., and officers must follow the "knock and announce" rule, waiting for a reasonable amount of time after announcing their authority and purpose before using force to enter a premises. During the search, officers are only permitted to search the places and individuals listed on the warrant, and any evidence found outside of the scope may be inadmissible in court.
There are some exceptions to the warrant requirement, including consent searches, motor vehicle searches, evidence in plain view, exigent circumstances, and border searches. Additionally, the amendment's protections have been extended beyond physical locations to include intrusions on the privacy of individuals, as ruled in Katz v. United States (1967).

Protection of personal property
The Fourth Amendment to the United States Constitution, passed by Congress on September 25, 1789, and ratified on December 15, 1791, protects the right to be secure in one's personal property, papers, and effects against unreasonable searches and seizures. This amendment 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 specifically describe the place to be searched and the items to be seized.
The Fourth Amendment places limitations on the power of the courts and federal officials, ensuring that the rights of individuals are protected against unreasonable searches and seizures, regardless of whether they are accused of a crime. This amendment was introduced to address concerns about the potential for unlawful seizures and forced confessions by those executing criminal laws, which could violate the rights guaranteed by the Federal Constitution.
The Fifth Amendment also plays a crucial role in protecting private property rights. It states that individuals cannot be deprived of their property by the government without due process of law, ensuring fair procedures are followed. Additionally, it places restrictions on eminent domain, the government's power to take private property for public use. When the government exercises eminent domain, the Fifth Amendment requires that the taking must be for a "public use" and that the property owner receives "just compensation" at market value.
The interpretation and application of these amendments have been the subject of numerous court cases, such as Kelo v. City of New London in 2005, where the Supreme Court broadly interpreted "public use" to include economic development, potentially benefiting private parties. This decision sparked debates about the strength of property rights protections and prompted state legislatures to pass laws clarifying the scope of eminent domain.
Overall, the Fourth and Fifth Amendments to the United States Constitution provide significant protections for personal property rights, safeguarding individuals against unreasonable searches, seizures, and the taking of their property without due process and just compensation.

Probable cause
The Fourth Amendment to the United States Constitution deals with search and seizure. It is part of the Bill of Rights, which was introduced in Congress in 1789 and ratified in 1791. 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". This means that warrants must be issued by a judge or magistrate and justified by probable cause. Probable cause is a central concept to the warrant clause, though neither the Fourth Amendment nor federal statutory provisions provide a definition; instead, it is a judicial construct.

Exceptions to the Fourth Amendment
The Fourth Amendment of the United States Constitution is part of the Bill of Rights, which prohibits unreasonable searches and seizures. It states:
> "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 places limitations and restraints on the courts and Federal officials in the exercise of their power and authority. However, there are several exceptions to the Fourth Amendment's warrant requirement.
Exceptions
Firstly, a warrantless search may be lawful if an officer has asked for and is given consent to search. Criminal suspects can voluntarily waive their Fourth Amendment rights and consent to a search of their person or property without a warrant.
Secondly, a warrantless search may be justified if it is incidental to a lawful arrest. In Terry v. Ohio, the Court clarified that police officers can stop a person if they have a reasonable suspicion of criminal activity. This type of investigative stop is known as a Terry stop and includes a limited stop and frisk for weapons to ensure officer safety.
Thirdly, a warrantless search may be lawful if there is probable cause and an exigent circumstance, such as imminent danger, imminent destruction of evidence, or a suspect's imminent escape.
Other exceptions include consent searches, motor vehicle searches, evidence in plain view, border searches, and other situations. For example, warrantless searches and seizures of objects in plain view do not constitute seizures within the meaning of the Fourth Amendment. Similarly, the warrant requirement does not apply to the seizure of abandoned property or property in an open field, as it is not reasonable to expect a right to privacy in these cases.
In summary, while the Fourth Amendment provides important safeguards against unreasonable searches and seizures, several exceptions allow law enforcement to conduct warrantless searches in specific circumstances. These exceptions are nuanced and evaluated based on the totality of the circumstances to balance the individual's right to privacy with the need to protect public safety and prevent the destruction of evidence.
