4th Amendment Flashcards
Definition of Seizure
A person is seized when, as the result of government action: a reasonable person in the situation would feel that they are not free to leave or to terminate the encounter with the officer.
Terry Stop
A Terry Stop is a “brief investigatory seizure.” There must be “Reasonable suspicion that crime is afoot.”
Permissible scope of a Terry stop
Time required to confirm or deny the suspicions when the officer is acting in due diligence.
Arrest
- Probable cause is always required.
- Police may arrest a suspect in public without a warrant, so long as he has probable cause.
- An arrest warrant is required: before the police can arrest an individual in the home. (UNLESS Exigent circumstances).
Exigent circumstances justifying a warrantless entry into the suspect’s home to execute an arrest
(1) an arrest attempt outside the home is thwarted because the suspect retreats into the home;
(2) there is insufficient time to secure a warrant because the delay would allow the suspect to evade arrest or destroy evidence; or
(3) the arresting officer is in “hot pursuit” and has probable cause to effect a valid arrest of the suspect.
- The officer must not have deliberately created the exigency just to avoid obtaining a warrant.
Seizure of Property
- A warrant based on probable cause is required to justify the seizure of property.
- No warrant is required if the property is: in plain view.
Plain view to seize the property
(1) the police are in a lawful vantage point to observe the item; and
(2) the incriminating nature of the item is: immediately apparent. (= Doesn’t require additional research).
Search
A search is a government intrusion into: the reasonable expectation of privacy.
A reasonable expectation of privacy requires:
1) A subjective expectation or privacy
2) An objective expectation of privacy
A valid warrant to search or seize must be:
(1) issued by a neutral and detached magistrate,
(2) based on probable cause, and
(3) describe with particularity the thing to be seized or place to be searched.
If there was a warrantless search or seizure, the government bears the burden to prove:
that the search or seizure fell within an established exception to the warrant requirement.
“Knock and Announce”
Police must normally “knock and announce” his identity before entering a home to execute a warrant.
Exception:
The police had a reasonable belief that knocking will endanger themselves, or lead to the destruction evidence or escape of the suspect.
Note:** Violation of the “knock and announce” rule violates the Fourth Amendment, but does not trigger the exclusionary rule.
A search warrant for a premises
A search warrant for a premises carries with it the right to detain persons there during the search, but not the right to search those persons.
Warrantless Searches
- Search incident to a lawful arrest
- Automobile exceptions
- Consent
- Hot pursuit
- Exigent circumstances
- The Terry Search
Search incident to a lawful arrest
