CRIM. PRO. Flashcards
4th Amendment
Protects against unreasonable searches and seizures by the government in areas in which a party has a reasonable expectation of privacy.
Searches and seizures typically require a warrant supported by probable cause, however, many exceptions apply.
Absent an exception, an evidentiary search or seizure without a warrant is unlawful.
Seizure of a Person
When a reasonable person in the ∆’s position would not feel free to leave or terminate the encounter with a government officer, they have been “seized” in terms of the 4th Amendment. Whether or not someone is seized is based on the totality of the circumstances, including a showing or physical force or authority.
The brief seizure of a person is lawful without a warrant if it is the result of a Terry stop conducted with reasonable suspicion, or an arrest with probable cause.
“Reasonable Suspicion”
More than just a “mere hunch”. There must be a belief based on articulable facts that a suspect has or is about to engage in criminal activity.
The presence of reasonable suspicion will justify a terry stop or cursory protective sweep of a suspect, aka, a “terry frisk”.
Probable Cause
A “fair probability” that the subject of the investigation committed a crime or that evidence of criminal activity can be found at a location.
Probable cause is required for searches and arrests.
Terry Stop
A “brief investigatory seizure” of a person for the time necessary to confirm or dispel the officer’s reasonable suspicion that a crime has or will occur.
A terry stop requires reasonable suspicion that a crime has or will occur based on articulable facts.
During a terry stop, an officer may pat for weapons for safety purposes, but not for the purpose of collecting evidence. However, if during a “terry frisk”, the officer has reasonable suspicion that the suspect is armed or has contraband in their pockets, it can be seized.
If the reasonable suspicion is confirmed and turned into probable cause, then the officer can arrest and conduct a search incident to arrest.
Terry Stop - “Reasonable Suspicion”
An officer must have more than a mere hunch that a crime was committed or is about to be committed in order to conduct a terry stop. This reasonable suspicion can be established by police or eyewitness observation, flight from police, or an informant tip that is then corroborated by police.
“Search” Definition Under the 4th Amendment
The government’s intrusion into one’s “reasonable expectation of privacy”.
The reasonable expectation of privacy must be both subjective (the suspect has actively tried to shield their property from the public), and objective (a reasonable person in society would recognize that property as private).
Items/places that are not protected by the reasonable expectation of privacy include things open to the public such as handwriting, voice, bank/phone records, trash/discarded property, or open fields.
Seizure of Property
When the government takes action that results in a meaningful interference with a possessory interest.
A warrant based on probable cause is presumptively required to seize property.
A warrant is not required to seize property that is in plain view, as long as the government was in a lawful vantage point in viewing it, the property is contraband, and the officer has lawful access to the item.
Sensory Enhancing Devices
If the device is generally available/accessible to the public, the use of said device is not considered a search and thus the 4th Amendment is not implicated.
If the device is specialized/tactical, like a heat sensor, it is a search, and the government would need a warrant unless an exception applied.
Open Fields Doctrine
There is no reasonable expectation of privacy in an open field, and therefore they are not constitutionally protected under the 4th Amendment.
When is a warrant NOT required to seize property?
- When there is probable cause to arrest in public for a felony or a misdemeanor committed in the officer’s presence.
- When reasonable suspicion exists for a terry stop.
- To seize property under the plain view doctrine.
Plain View Doctrine
A warrant is not required to seize evidence in plain view, as long as the officers viewed the property from a lawful vantage point, the item seized was reasonably contraband, and the officer has lawful access to the point of seizure.
When is a search not “reasonable” under the 4th Amendment, even if there is a warrant?
A valid warrant creates a presumption of reasonableness, but a search with a warrant can still be unreasonable if —
- The warrant was “stale” = not executed within 10 days in GA.
- The officers did not knock and announce (although this will not exclude evidence obtained as a result).
- The officers seized property outside of the scope of the warrant.
Validity of a Warrant
A valid warrant must be issued by a neutral and detached magistrate, must be supported by probable cause under oath or affirmation, and must state with specificity the property to be seized and searched.
Under the good faith exception, an invalid warrant will not exclude evidence unless it was so lacking in probable cause that no rookie officer would have believed its validity.
Warrant Exceptions
A search and seizure without a valid warrant is unreasonable unless it falls under an exception — ESCAPSS

Search incident to lawful arrest.
