Criminal Procedure Flashcards
Probable Cause for an Arrest
trustworthy facts or knowledge sufficient for a reasonable person to believe that the suspect has committed or is planning to commit a crime
Arrests
An arrest occurs when police take an individual into custody for purposes of criminal prosecution or interrogation
Probable cause is always required for any valid arrest.
warrants are rarely required for arrests.
Warrants for Arrest
Police generally do not need a warrant before arresting a person in a public place
EXCEPT:
Polce must have an arrest warrant to arrest an individual in their home and may only enter the home if they have reason to believe the suspect is in the home.
Note: Search Warrant is required to execute an arrest of suspect in a third party’s home.
Note: arrest warrant is not required for an emergency arrest occurring in the arrestee’s home.
Detention
a governmental seizure of a person that is less than a full custodial arrest
i.e.
(1) Stop & Frisk (Terry Stop) - requires reasonable suspicion
(2) Automobile Stop - reasonable suspicion
(3) Stationhouse detention - probable cause required to compel a person to enter
(4) Detention to obtain search warrant - requires probable cause to believe suspect has contraband in the home and a reasonable time is required to permit entry and potential destruction of evidence.
(5) Detention of occupants of a premises - during exercise of a valid search warrant
Automobile Stops
Stopping or pulling over a vehicle requires a reasonable suspicion that a law has been violated.
Pretextual stops (i.e. ulterior motive) are OK if police have probable cause of a traffic violation.
Automobile Stops - Accompanying Searches
Passengers and the passenger compartment (but not the trunk) can be searched during an automobile stop if the officer reasonably believes weapons may be present.
Officer can order passengers out of the vehicle.
Entire car may be search if probable cause arises during the automobile search OR incident to a lawful arrest.
Police checkpoints
must related to a vehicle-specific purpose
(1) Cars must be stopped using a neutral, articulable standard; and
(2) Serve purposes related to automobiles and their mobility
i.e. DUI checks relate to road safety. Drug checkpoints are not.
Validity of Govt. Searches and Seizures
must be reasonable under the 4th amendment, which requires a valid search warrant unless one of six exceptions applies
Exceptions to the Search Warrant Requirement
(1) Search Incident to arrest
(2) Plain view search
(3) Automobile search
(4) Valid consent to search
(5) Exigent circumstances
(6) Stop & Frisk
Determining the reasonableness of a search/seizure
(1) Is there govt. conduct constituting a search or seizure?
(2) Does D have standing? (i.e. a reasonable expectation of privacy in the thing or place to be searched).
(3) Is there a valid search warrant?
(4) If there is no valid search warrant, was there a valid exception to the search warrant requirement?
Reasonable Expectation of Privacy
4th only applies if there is a reasonable expectation of privacy (REOP) regarding the thing or place searched and/or item seized.
Determined by the totality of the circumstances.
No REOP in inherently public things (i.e. handwriting, voice, location, odors, public records, things viewable from a public space, bank account records, areas outside the curtilage of the house).
Automatic standing (i.e. REOP always exists) if D either:
(1) owns, has a right to possess, or lives in the premises to be searched, or
(2) is an overnight quest of the premises to be searched.
Requirements for a Valid Search Warrant
(1) Based on probable cause - usually, a police affidavit containing facts and information from anonymous sources that demonstrate the search will produce evidence.
(2) Precise on its face - the warrant must describe with reasonable precision the place to be searched and items to be seized.
(3) Issued by a neutral and detached magistrate.
Note re: Anonymous Sources - if (1) there was a false statement, (2) affiant intentionally or reckless included the false statement, and (3) false statement was material to finding probable cause then the warrant is invalid.
Good faith exception to an invalid search warrant
The exclusionary rule does not apply if the police act in good faith on an invalid search warrant.
Police however cannot rely on a defective warrant obtained in good faith if:
(1) Affidavit completely lacks probable cause (i.e. no reasonable officer would have relied)
(2) Warrant is defective on its face
(3) Police/Official lied or misled the magistrate. or,
(4) Magistrate has “wholly abandoned her judicial role”
Execution of Search Warrants
(1) Timing - without unreasonable delay once issued
(2) Knock and Announce Required - knock and announce their purpose and wait a reasonable time for admittance before entering of own accord
Note: UNLESS officers have reasonable suspicion that announcing their presence would be dangerous, futile, or would inhibit investigation
(3) Scope of Search - limited to what is reasonably necessary to discover items described.
I.e. Police can detain people on premises but cannot search unless they are specifically named or a valid exception exists.
Search Incident to a Lawful Arrest
Police may search a lawfully arrested person and his immediate surrounding area without a warrant if:
(1) The arrest is lawful
(2) Search is contemporaneous with the arrest
(3) Search is limited to area within suspect’s reach or movement
Protective Sweeps allowed if reasonable belief accomplices may be present
Inventory Searches of arrestee’s belongings or seized property is allowed when jailing arrested suspects.
Automobile Searches Incident to Arrest
After arresting an occupant of a vehicle offers may search the interior including glove box if at the time of the search
(1) Arrestee is unsecured and may access the interior, or
(2) Officers reasonably believe evidence of the crime for which the arrest was made may be found in the vehicle.
Does not include the truck without probable cause or consent!
A warrantless breathalyzer is valid following a lawful arrest based on probable cause of drunk driving.
Contents of a cellphone may NOT be searched.
Plain View Searches
Police may search from any place where they are legitimately present when viewing without a warrant if:
(1) Police are legitimately on the premises from which they viewed evidence to be seized;
(2) Criminal activity or contraband is immediately apparent; and
(3) Police have probable cause to believe that plainly viewed evidence is contraband or relates to a crime.
Scope: anything viewable from land or public property even if only viewable through binoculars (includes smell)
Cannot use technology not generally available to the public to view evidence (i.e. infrared scanners).
Consent to Search
Police may search for anything with valid consent.
Requirements:
(1) Voluntarily and intelligently made
(2) Person giving consent has reasonably apparent authority, to consent
Scope: can be limited by the consenting party
Third-Party Consent to a Search
Allowed if there is authority to consent
(1) Where multiple people have property rights any single one can consent to search of any area where they have authority to consent
(2) Resident trumps non-resident
(3) Scope of consent is dictated by the person present with highest authority to consent
(4) Refusal trumps consent (if equal rights)
Automobile Search Exception
If probable cause exists, police may search the ENTIRE vehicle and containers inside that.
Requirements:
(1) Police must have probable cause to search the vehicle; and
(2) Probable cause must arise before the search begins
Scope: Entire vehicle and all containers that might contain evidence sought after including passengers and their belongings.
Stop & Frisk (TERRY STOPS)
Police may detain a person for an investigative purpose if they have reasonable suspicion of criminal activity
Scope:
Length - no longer than necessary to verify suspicion
Frisk - must have reasonable suspicion of the person being armed/dangerous
Frisk is “plain feel” meaning police cannot manipulate the item to develop a reasonable belief of a weapon
A stop is only a brief detention so it’s less than an arrest but can lead to an arrest if evidence causes probable cause.
Exigent Circumstances
If exigent circumstances exist, police can search or seize without a warrant.
Hot Pursuit, Evanescent Evidence, and emergencies are forms of exigent circumstances.
