Police conducted a search of Jardines' home by bringing a drug-sniffing dog to his front porch, which resulted in a positive alert for narcotics. This led to a search warrant that uncovered marijuana plants, resulting in charges against Jardines for cannabis trafficking. The Supreme Court of Florida upheld a trial court ruling to suppress the evidence, determining the officers had conducted a Fourth Amendment search without probable cause. The Supreme Court affirmed this decision, ruling that the investigation constituted a "search" under the Fourth Amendment due to physical intrusion on the curtilage of the home. The front porch, as part of the home’s immediate area, is protected from unreasonable governmental intrusion. The officers' entry to the curtilage was not authorized, as their purpose was to conduct a search rather than to engage with the occupants, which falls outside customary invitation. The Court did not address whether Jardines had a reasonable expectation of privacy under the Katz standard. The opinion was delivered by Justice Scalia, joined by Justices Thomas, Ginsburg, Sotomayor, and Kagan, with a dissenting opinion filed by Justice Alito, joined by Chief Justice Roberts and Justices Kennedy and Breyer.

The Supreme Court case of Florida v. Jardines examines whether the use of a drug-sniffing dog on a homeowner's porch constitutes a "search" under the Fourth Amendment. In 2006, Detective William Pedraja received an unverified tip about marijuana cultivation at Joelis Jardines' home. A month later, a surveillance team, including Detective Pedraja and canine handler Detective Douglas Bartelt, approached Jardines' residence. The dog, trained to detect various drugs, began to sniff around the porch and ultimately sat at the base of the front door, indicating the presence of narcotics.

After the dog’s alert, Detective Pedraja obtained a search warrant based on this information. However, Jardines sought to suppress the evidence from the search, arguing that the canine investigation was an unreasonable search. The trial court agreed, leading to a reversal by the Florida Third District Court of Appeal. The Florida Supreme Court ultimately quashed the appellate decision, affirming the trial court's ruling that the canine sniff constituted a Fourth Amendment search lacking probable cause, thus invalidating the warrant obtained from that search.

Certiorari was granted to determine if the officers’ actions constituted a search under the Fourth Amendment. The Fourth Amendment protects individuals from unreasonable searches and seizures, establishing that a search occurs when the government physically intrudes on protected areas. The ruling in Katz v. United States clarified that property rights are not the only measure of Fourth Amendment violations; however, physical intrusion into constitutionally protected areas remains a key factor. In this case, the officers collected information within the curtilage of Jardines' home, an area recognized as enjoying the same protections as the home itself. 

While the Fourth Amendment allows for some investigations on private property, such as in "open fields," it emphasizes the home as a primary sanctuary against government intrusion. The curtilage, which includes the area immediately surrounding the home, is considered part of the home for Fourth Amendment purposes. This principle, rooted in common law, highlights the intimate connection between the home and its curtilage, where expectations of privacy are most pronounced. The ruling underscores that police cannot enter this area to gather evidence without violating Fourth Amendment protections.

The concept of "curtilage," which refers to the area immediately surrounding a home, is well understood and recognized in legal terms. In this case, law enforcement officers entered the curtilage by stepping onto the front porch, a traditional extension of the home where home activities occur. Since this area is constitutionally protected, the investigation's legality hinges on whether the officers' entry constituted an unlicensed physical intrusion. While officers can observe a home from public areas, their authority is limited when they enter protected spaces. A significant precedent states that individuals are entitled to the sanctity of their property, requiring permission for entry. Although the State argued that the officers had a right to be where they were, the record shows that Jardines only acknowledged that officers could lawfully approach his door to knock, not that they could enter the curtilage. Implied licenses exist based on social norms, allowing visitors to approach and knock at the door, but these licenses do not extend to law enforcement without a warrant. The permission to approach a home is generally understood and does not require intricate legal knowledge, as evidenced by common social practices. The court emphasizes that any entry beyond a standard visit requires explicit permission, and the dissent raises valid points about expectations for visitors' behavior.

The dissent's reasoning is inconsistent with established norms regarding the use of trained dogs to investigate the curtilage of a home, as there is no customary practice permitting a stranger to conduct such an exploration. Introducing a police dog to search the area around a home for incriminating evidence constitutes a significant intrusion, diverging from typical social norms associated with visiting a residence. While a visitor knocking on a door is customary, conducting a search with a trained animal would alarm most homeowners. The scope of any implied license for visitors is limited to specific areas and purposes, and consent given during a traffic stop does not extend to unrelated searches. 

The dissent incorrectly views the use of a dog as the core issue; rather, it is the searching behavior that is problematic. The presence of an unfamiliar person conducting a search, regardless of the tool used, would likely prompt concern. The dissent suggests that police may gather evidence as long as they remain on traditional pathways to the door, yet this interpretation is not supported by law. The distinction made in precedent regarding the subjective intent of an officer does not apply here, as the focus is on whether their actions constituted a reasonable search under the Fourth Amendment. The officers' entry onto the porch indicated an intent to conduct a search, which exceeds any implied license for visitors. The State’s claim that using a narcotics detection dog does not infringe upon privacy interests lacks merit in this context.

The State references prior Supreme Court rulings, specifically United States v. Place, United States v. Jacobsen, and Illinois v. Caballes, which determined that canine inspections of luggage, chemical testing of substances, and canine inspections during lawful traffic stops do not infringe on the "reasonable expectation of privacy" established in Katz. However, the Court emphasizes that individuals are not impliedly invited to have searches conducted within the privacy of their homes. In Jones, the Court ruled that using a GPS to track a vehicle constitutes a Fourth Amendment search, rejecting the argument that a lack of reasonable expectation of privacy on public roads negates this classification. The Court clarified that the Katz standard is an addition to, not a replacement for, traditional property-based Fourth Amendment protections; thus, physical intrusion into protected areas is sufficient to establish a search. The Court found the State's argument regarding the historical use of forensic dogs irrelevant, affirming that using trained dogs to investigate a home constitutes a "search" under the Fourth Amendment. Consequently, the Supreme Court of Florida's judgment was upheld.

Justice Kagan, joined by Justices Ginsburg and Sotomayor, emphasizes the importance of both privacy and property rights in this case. She uses an analogy of a stranger using high-powered binoculars to invade a person's home without consent to illustrate the invasion of privacy. Kagan asserts that the police, like the stranger, trespassed by using a specialized drug-detection dog to uncover details inside Joelis Jardines’ home that were not visible without this tool. She argues that this method is akin to using binoculars rather than a regular dog, which are trained instruments of law enforcement designed to detect specific scents. Kagan concludes that the police action constituted both a trespass and a violation of Jardines' reasonable expectation of privacy. While the Court focuses on property law, she notes that a privacy-based decision would yield similar conclusions regarding the right to be free from unreasonable government intrusion in one's home. Kagan highlights that expectations of privacy are most pronounced in the home environment, and that property law influences societal norms about what areas should be protected from government searches.

The sentiment that "my home is my own," rooted in property law, extends to a broader understanding of privacy within the home. Jardines’ home, as both property and intimate space, is central to this analysis. If the case were decided on privacy grounds, it would align with Kyllo v. United States, which established that using a thermal-imaging device to detect heat from a home constitutes a search, even without physical intrusion, and is presumptively unreasonable without a warrant. The ruling emphasized a clear boundary regarding privacy at the entrance to a home, where government use of non-public devices to uncover private details is prohibited. 

The dissent references Illinois v. Caballes, which involved a dog sniff during a traffic stop, but the precedent distinguishes between privacy expectations in vehicles and homes. In Jardines, the police used a drug-detection dog—a device not in general public use—to search for substances within the home, thus violating the reasonable expectation of privacy. The dissent's argument that the presence of a dog does not constitute a search is countered by Kyllo, which asserts that the use of any non-public tool to detect hidden details within a home infringes on privacy rights. Moreover, while police may detect odors emanating from a residence, this does not diminish the homeowner's expectation of privacy regarding scents that are not typically detectable from the outside.

The excerpt addresses the legality of police actions under the Fourth Amendment concerning the use of thermal imaging and the concept of trespass. It argues that alternative methods of gathering information do not justify violating the Fourth Amendment. At the time in question, the heat emanating from a home was not discernible to an outside observer, thus necessitating a warrant or exigent circumstances for police searches. Justices express differing views on the definition of trespass, with Justice Alito dissenting. He contends that existing trespass law allows the public, including police, to approach a home's front door without special intent to speak with the occupant. Alito challenges the Court's conclusion that the presence of a dog during the officer's visit constituted a trespass, arguing that no precedent supports such a rule. He asserts that the reasonable-expectations-of-privacy standard should recognize that odors from a house can be detected from public areas. Ultimately, he believes no search occurred under the Fourth Amendment and would reverse the lower court's decision.

The Court's opinion may mislead readers into believing that Detective Bartelt and Franky spent an extended time on the respondent's property conducting a thorough search. In reality, they approached the front door via a typical route and used a standard leash for Franky. As they neared the door, Franky detected an airborne odor and began to track it, leading him to sit at the door's base, indicating he had found the source. This entire process lasted approximately one to two minutes, a detail omitted by the Court. Additionally, while Detective Bartelt did not personally smell marijuana, another officer, Detective Pedraja, detected the odor later. The Court deemed the actions a search, claiming Bartelt exceeded the permissible license to approach the house, which Alito contests. He argues that public custom allows individuals to walk to a home’s front door, which includes various categories of visitors, ranging from friends to solicitors.

The law differentiates between various types of visitors, such as acceptable door-to-door salespeople and police officers on specific missions, but it does not create a complex classification system for trespass. Consent for entry is recognized legally, even if the entrant’s intentions would lead the property owner to withdraw consent. Determining whether a business invitation is implied relies on objective assessments of custom and appearance rather than the visitor's undisclosed intentions. Visitors must adhere to typical pathways when approaching a property; deviations into private areas, like gardens or backyards, exceed the implied invitation. Law enforcement can observe from areas accessible to ordinary visitors, but their entry must remain within expected limits. Additionally, visiting late at night or lingering at the front door is generally not permissible without explicit invitation, as these behaviors may cause alarm to residents. The implied license for visitors is time-bound, limited to a brief period to approach the door and ascertain if someone is home, without the necessity to engage further unless invited.

Mail carriers, delivery personnel, and individuals distributing flyers can leave items without conversing, and pedestrians or motorists may approach a front door to check hard-to-see house numbers or retrieve newspapers. This implied license to approach extends to police officers, who do not conduct a search when they engage in a "knock and talk" to gather evidence, as established in Kentucky v. King. Officers without a warrant perform actions no different from those of a private citizen. They are allowed to observe what is visible from lawful vantage points. The Fourth Amendment does not require officers to shield their eyes from what is visible on public thoroughfares. Detective Bartelt did not exceed this implied license when approaching a front door, adhering to customary behavior and remaining for a brief period. The Court's conclusion that his actions constituted a search due to his purpose to gather evidence is problematic, as it implies that most police visits, including standard "knock and talks," would also be considered searches. The distinction the Court makes—that a "knock and talk" involves conversation, which all are invited to do—is not a meaningful differentiation from Bartelt’s actions.

A police officer approaching a home's front door may collect evidence without verbal communication, utilizing observations of items in plain view and odors emanating from the residence. The Court’s claim regarding the “objective purpose” of the officer’s actions is challenged by the use of a dog to detect marijuana odors. Common law does not indicate that a visitor accompanied by a leashed dog commits trespass, and historical practices even allowed unleashed dogs on private property without trespass implications. The dissent argues that the use of a dog does not constitute trespass and underscores that no legal precedent exists to support the notion that a dog’s presence at a front door is inherently trespassory. Furthermore, the dissent critiques the concurring opinion's assertion that the officer’s actions breached the occupant's reasonable expectation of privacy, referencing previous rulings that deny a reasonable expectation of privacy for odors detectable by the public. Upon detecting the odor of marijuana, officers had probable cause to believe contraband was present, reinforcing the notion that there is no reasonable expectation of privacy regarding odors that can be perceived by individuals in lawful positions. The dissent posits that an occupant engaged in illegal activities, such as marijuana cultivation, would not expect privacy concerning detectable odors.

Odors emanating from a building can be influenced by wind conditions, which affect their strength at locations where the public may legally stand. The author acknowledges variability in human olfactory sensitivity and notes that, while some odors may be detectable by dogs, they would likely be too faint for humans to smell. The author critiques the argument that a reasonable expectation of privacy exists regarding the odor of marijuana from a residence, contrasting it with *Kyllo v. United States*, a case concerning the use of thermal imaging to detect heat from a home. The court in *Kyllo* ruled that such technology was not commonly in public use and raised concerns about citizens being vulnerable to invasive technological advances. However, the author points out that using a drug-sniffing dog is not comparable to thermal imaging, as dogs have been utilized in law enforcement for centuries and do not constitute new technology. The dissent argues that the police conduct in this case did not violate the respondent's reasonable expectation of privacy, asserting that the use of a dog to alert on a public sidewalk or within a legally accessible area does not constitute a search. The author expresses concern that equating a dog’s sense of smell with thermal imaging would unjustly restrict law enforcement’s ability to act.
