Crim Pro 4th Amendment Flashcards
What is the 4th amednment?
The right of the people to be secure in their persons, houses, papers, and effects, against
unreasonable searches and seizures by the government without a valid warrant that is supported by a probable cause +oath or affirmation + issued by a neutral judicial officer. Describing “ particularly” the place to be searched, and the persons or things to be seized.
Searches defined
A search is an invasion of a protected privacy interest.
The Supreme Court has set out a two-pronged test to determine whether a privacy interest exists
1) First, there must be an expectation of privacy that society is prepared to regard as reasonable. This prong refers to objective reasonableness, and
2) Second, there must be a subjective expectation of privacy on the part of the individual.
Example of a reasonable expectation of privacy #1
A retreats into a closed telephone booth and speaks in a quiet voice to B. A believes his conversation will remain private, and society regards this expectation as reasonable. Therefore electronic interception of A’s conversation constitutes a search.
Example of a reasonable expectation of privacy #2
If A possess illegal drugs in his home, but A leaves the window shade up so that the drugs are visible from the street, then the objective privacy accorded individuals for activity in their homes would be lost because A did not take adequate steps to ensure his privacy. To put it another way, even if A had a subjective intent to keep it private, this is not an expectation society would recognize as reasonabl
Who bears the burden of proof to establish the objective reasonableness of privacy expectation.
The Defendant
What are the Protected Areas that requires a warrant to be searched? (3)
1) House
2) Curtilage
What is considered a house in the context of searches?
“House” is broadly construed to include virtually all structures that people commonly use as residences, whether on a temporary basis, such as:
1) a hotel room or
2) on a long-term basis, such as an apartment.
Houses also include buildings connected to a residence such as a garage.
Offices, stores and other commercial buildings are included within the term
What is considered a house in the context of Curtilage.?
Curtilage refers to the area surrounding a home that is associated with the privacy and sanctity of a person’s residence.
A barn is generally not considered part of the curtilage, while areas like a front porch or backyard would be included.
Factors that determine the extent of the curtilage include:
1) Proximity of the area to the home.
2) Whether the area is within the enclosure surrounding the home.
3) The nature of the area’s uses.
4) Steps taken to protect the area from observation.
What about searching Open fields?
Protection does not include open fields or vacant and undeveloped land outside the curtilage.
For this reason, entry onto an open field is not covered by the Fourth Amendment, and none of its requirements (e.g., probable cause, warrant) apply
What is “papers” in the context fo the 4th amendment?
“Papers” encompass personal items, such as letters, diaries, and pictures, as well as impersonal business records.
what is “effects” in the context of the 4th amendment?
automobiles, luggage, other containers, clothing, weapons, and even the fruits of a crime.
privacy is evaluated in terms of
reasonable expectations
Tor F: A nonsearch is not
regulated by the Fourth Amendment (only searches trigger 4th amednment ); it may be done for no reason or any reason at all.
True.
What are some police actions that do not amount to searches: (7)
1) Plain View
2) Beepers and other enhanced technology
3) Aerial surveillance
4) Canine sniffs
5) Conversations
6) Garbage
7) Pen registers
What is plain view?
is a legal concept that allows law enforcement officers to seize evidence without a warrant if the evidence is plainly visible from a lawful vantage point.
Plain view doctrine: According to the plain view doctrine, if a law enforcement officer is lawfully present in a location and sees an object or evidence that is immediately recognizable as contraband, illegal activity, or evidence of a crime, they can seize it without a warrant.
Three requirements: For a plain view search to be valid, three conditions must be met:
1) The officer must be lawfully present in the location where the evidence is observed.
2) The incriminating nature of the evidence must be immediately apparent (i.e., without further search or investigation).
3) the officer must have a lawful right of access to the evidence.
What is the scope of plain view search?
Limited scope: The plain view doctrine only allows for the seizure of evidence that is in plain sight. It does not permit officers to conduct a further search or manipulate objects to find additional evidence.
If an officer’s plain view observations lead them to believe that further evidence of a crime exists, they can use those observations as..
probable cause to obtain a search warrant for a more extensive search.
How can Beepers and other enhanced technology be valid and not trigger search under the 4th amendment?
2
If the enhanced technology merely increases the depth of information not otherwise protected by an expectation of privacy, the government’s use of enhanced technology to see or hear better is not a search.
However, Law enforcement’s use of sense-enhancing technology to see details of a private home that would not be discoverable without physically entering the home constitutes a Fourth Amendment search.
e.g.:
The use of a hidden beeper to track a barrel of chloroform (used to manufacture speed) was not an invasion of privacy where the information gleaned consisted of movements over public highways. However, if the monitoring continued after the barrel was taken inside a house and was no longer visible from outside, then a beeper locating the barrel within the structure constitutes an invasion of privacy
Training a thermal imaging device that reveals heat patterns within the home (indicative of marijuana grow lights), constitutes a search.
Aerial surveillance valid search that does not trigger search within 4th amendmen?
Aerial surveillance, such as the use of airplanes, helicopters, drones, or satellite imagery, can be a valid form of search under the Fourth Amendment in certain circumstances.
1) Activities conducted in open spaces visible from the air, such as open fields or public streets, may not trigger Fourth Amendment protections.
2) law enforcement has a right to fly over navigable airspace, which includes the airspace above private property, without violating the Fourth Amendment. Therefore, if aerial surveillance occurs within the legally permissible airspace, it may not require a warrant.
3) Navigable airspace for fixed-wing aircraft is above 1,000 feet;
and there is no minimum level for helicopters.
Note: So far, all aerial surveillance has been
approved
Do Canine sniffs amount to unconstitutional search?
Exposure of luggage, located in a public place or another place where the drug detection dog is authorized to be, to a “canine sniff” does not amount to a search because a “canine sniff” by a well-trained dog is 1) less intrusive than opening the luggage, and 2) the information obtained is limited to presence or absence of narcotics.
Do people have a reasonable expectations of privacy when it comes to conversations?
An individual is held to assume the risk that anything said to another, or in their presence, may be revealed, recorded, or transmitted by their auditor.
Any person may be surveilled in this way outside the Fourth Amendment.
Thus, an informer, even one planted by the government, may reveal what she has heard the defendant say. She may also wear a wire or transmitter to record the conversation or broadcast it to another officer. No warrant or probable cause is required. If they are properly authenticated, tapes and listener testimony may be offered by the prosecution.
What is the limitations to conversations searches?
It requires that one of the participants consents to reveal the contents of the conversation.
Electronic surveillance may not be used against persons who would otherwise have an expectation of privacy in their conversations without the consent of one of the participants.
Unless someone was loud in a public place (no reasons for privacy expectations) AKA: eavesdropping.
