Privately paid police deputized with the power to arrest
Public school officials
What is a 4th Amendment search?
A 4th Amendment search is a governmental invasion of a person’s constitutitionally protected reasonable expectation of privacy
What is the Kats test?
- The defendant exhibits an actual, subjective expectation of privacy, and
- Society is prepared to recognize that expectation as reasonable
What is the Jones test?
A search occurs when the government physically intrudes (trespasses) on a constituionally protected area (person, home, papers, effect) for the purpose of obtaining information.
- Ex: Government installation of a GPS device on an individual’s vehicle—an “effect” under the 4th Amendment—and the use of that device to monitor the vehicle’s movement constitutes a search.
What is the exeption/corollary to a 4th Amendment Search under Kats and Jones?
If someone knowingly/voluntarily exposes something to society, the public, or a third-party, then it is NOT a search and protected under the Fourth amendment.
Thus, society may have an expectation of privacy for someone’s fenced in backyard, but this expectation is defeated when it is knowingly exposed it
Is a government intrusion into an open field a search?
No. Because open fields are not persons, houses, papers, or effects, a government intrusion upon an open field is not an unreasonable search proscribed by the test of the Fourth Amendment.
A government intrusion into a privately owned open field is also not a search because an individual may not legitimately demand privacy for activities conducted outside in fields, except in the curtilage—the area immediately surrounding the home
What is curtilage?
The area immediately surrounding the home?
How do court’s define the extent of a home’s curtilage?
In defining a home’s curtilage, Courts consider whether the area in question is so intimately tied to the home itself that it should be placed under the home’s umbrella of Fourth Amendment protection. In making that determination, a court should consider the following factors:
* The proximity of the area claimed to be curtilage to the home
* Whether the area is included within an enclosure surrounding the home
* The nature of the use to which the area is put
* The steps taken by the resident to protect the area from observation by passerby
Are aerial observations of a home’s curtilage a search?
No. Aerial observation of a home’s curtilage is not a search if the curtilage is visible from the public navigable airspace.
An individual’s expectation that his curtilage or garden is protected from such observation is unreasonable and not an expectation that society is prepared to honor
Is the government’s use of a thermal imagine device, or a similar device not in the general public’s use, a search under the 4th Amendment?
Yes, when a government actor uses a thermal imaging device, or a similar device that is not in the general public’s use, to explore details of the home that would previously have been unknowable without physical intrusion, the surveillance is a “search” and is presumptively unreasonable without a warrant.
Is it a search when government actors gather and sort through a person’s trash left for collection outside the curtilage of a home?
No, because trash left for collection on a public street is readily accessible to others, including the garbage collector, so it is not objectively reasonable to expect that its content will remain private.
Is there a search when government actors install a tracking device on property not yet owned by the defendant and then uses the device, once in the defendant’s position, to reveal information of his public movements?
No. A person traveling on public thoroughfares has no reasonable expectation of privacy in his movements from one place to another. Information regarding one’s public movements could also be obtained through ordinary visual surveillance.
Different from Jones where is car was tracked 24/7 for 28 days
Is there a search when government actors use a tracking device to obtain information about the interior of a private residence that they could not have obtained by observation from outside the curtilage?
Yes a search does occur. Private residences are places in which the individual normally expects privacy free of governmental intrusion not authorized by a warrant, and that expectation is one that society is prepared to recognize as reasonable.
*United States v. Knotts *(compare with United States v. Karo)
Is the government’s use of a pen register a search?
No, an individual does not generally expect the numbers he dials to remain secret, nor is it reasonable to expect privacy in information voluntarily disclosed to third-party telephone companies whose equipment completes the call
Is the government’s use of a narcotics detection dog to sniff a person’s luggage in a public airport a search?
No, the use of a narcotics detection dog to sniff a traveler’s luggage in a public airport does not constitute a search under the Fourth Amendment.
Drug sniffing dogs only reveal the presence of contraband (nothing more) and people have no privacy interest in contraband.
Is the government’s use of a narcotics detection dog to sniff a person’s vehicle during a lawful (justified at its inception) traffic stop?
No, as long as the sniff does not prolong the traffic stop.
Drug sniffing dogs only reveal the presence of contraband (nothing more) and people have no privacy interest in contraband.
Does the government’s use of a narcotics detection dog to sniff a person’s vehicle after the completion of a lawful (justified at its inception) traffic stop violate the Fourth Amendment?
Yes, the use of a narcotics detection dog to sniff an individual’s vehicle after the completion of a lawful (justified at its inception) traffic stop constitutes an unlawful seizure under the Fourth Amendment.
Does the use of a narcotics detection dog to sniff an individual’s home and its immediate suroundings a search?
Yes, the home and the curtilage are constitutionally protected areas, and bringing a drug-sniffing dog onto the premises is an unlicensed physical intrusion.
What is probable cause for a search?
Probable cause for a search exists where the facts and circumstances within an officer’s knowledge and of which she has reasonably trustworthy information are sufficient in themselves to warrant a person of reasonable caution in the belief that an offense has been or is being committed and that the evidence bearing on that offense will be found in the place to be searched.
What is probable cause for an arrest?
Probable cause for an arrest exists where the facts and circumstances within an officer’s knowledge and of which she has reasonably trustworthy information are sufficient in themselves to warrant a person of reasonable caution in the belief that an offense has been or is being committed by the person whom the officer intends to arrest.
What approach/standard does the Court use determining probable cause?
Court’s use a totality of the circumstances approach and consider factors such as (1) a reliable source of information, including the source’s basis of knowledge; (2) detailed information suggestive of criminal activity; (3) verification or corroboration of the information by the police
AND
Probable cause is an objective standard focused on what a “reasonable officer” would believe with the same knowledge and information. The subjective beliefs and motivations of any particular officer are not relevant to the probable cause determination.
Mistakes of law are permissible so long as they are reasonable (e.g., police officer reasonably believed the law required two working headlights; probable cause to stop a car)
How does probable cause work for a narcotics detection dog?
In determining whether drug detection dog is reliable, the question is whether all facts surrounding dog’s alert, viewed through lens of common sense, would make reasonably prudent person think that search would reveal contraband or evidence of crime.
* Evidence of drug detection dog’s satisfactory performance in certification or training program can itself provide sufficient reason to trust his alert; if a bona fide organization has certified a dog after testing his reliability in controlled setting, the court can presume, subject to any conflicting evidence offered, that dog’s alert provides probable cause to search
What makes a valid search or arrest warrant?
- issued by a neutral and detached magistrate
- supported by probable cause sworn by oath or affirmation
- particularly describe a place to be searched and the persons or things to be seized
The magistrate need not be a lawyer of judge, but he must be capable of determining probable cause and must not have financial interests or connections to law enforcement that would compromise his independence
What are the possible issues concerning compliance with the warrant requirements?
- Police must knock and announce their presence before entering a residence to execute a search warrant, absent exigent circumstances
- Police may not search a person on the premises while executing a search warrant without individualized suspicion
- Police may detain a person on the premises while executing a search warrant, if necessary for officer safety or other legitimate reason
