26. Criminal Procedure and Evidence Flashcards
Detention by Officers
To detain someone for ANY PERIOD OF TIME officers must have reasonable suspicion that they committed a crime
Reasonable Suspicion
a belief that the suspect committed a crime
the belief must be based on more than a hunch,
rather, on ARTICULABLE FACTS
Warrantless Vehicular Search
to justify a warrantless vehicular search incident to the arrest conducted AFTER vehicle’s recent occupants have been secured . . .
4th am requires:
- ACTUAL and CONTINUING threat to officer safety posed by an arrestee OR
- a need to preserve evidence related to the crime of arrest
Fourth Amendment
provides persons should be free in their persons and effects from unreasonable searches and seizures
When search and seizure prohibitions apply
search and seizure prohibitions apply only when law enforcement officers search for evidence in a place where a person has a “reasonable expectation of privacy.”
a SEIZURE must be supported by probable cause or reasonable suspicion the suspect committed the crime
Reasonable Expectation of Privacy
based on a totality of the circumstances, considering factors such as ownership of the place searched and location of the item seized
Seizure
when under the totality of the circumstances, a reasonable person would feel he was NOT free to go
Warrant Requirements
- issued by a neutral and detached magistrate
- based on probable cause established from facts submitted to magistrate by gov agent upon oath/ affirmation
- describes the place to be searched and items to be seized with particularity
4th amendment requires officers to get a warrant if no exception applies
Exceptions to Warrant Requirement: Warrantless Search
= when warrantless search is reasonable and valid under 4th am
- automobiles
- plain view
- consent
- exigent circumstances
- search incident to lawful arrest
- searches incident to impoundment
NO exception for search of home EVEN IF officers have probable cause
Warrant Exception: Automobiles
if police have probable cause to believe a vehicle may contain evidence, contraband, or a fruit or instrumentality of a crime they can search vehicle without a warrant
if have FULL probable cause, they can search entire vehicle AND ALL CONTAINERS within the vehicle that may contain the object they are searching for
Warrant Exception: Plain View
police may make warrantless seizure when they are:
- legitimately on the premises
- discover evidence, contraband, or a fruit or instrumentality of a crime
- see such evidence in plain view AND
- have probable cause to believe the item is evidence, contraband, or a fruit or instrumentality of a crime
Warrant Exception: Consent
police may conduct valid warrantless search if they have voluntary consent to do so
- scope of search limited to scope of consent (extends to any place reasonably believes it extends to)
Warrant Exception: Consent of Another Person
person with apparent equal right to use or occupy the prop may consent to a search and evidence found may be used against owners/occupants
- CONSENT TO SEARCH IN A DWELLING IS INVALID IN THE PRESENCE OF AN OBJECTING CO-OCCUPANT
Warrant Exception: Exigent Circumstances
- hot pursuit
- destruction of evidence
- evanescent evidence
- emergency aid
Exigent Circumstance: Hot Pursuit
police in hot pursuit of a fleeing felon may make a warrantless search and seizure
Exigent Circumstance: Destruction of Evidence
police may enter home without warrant to prevent the destruction of evidence
police must have reason to believe evidence is being destroyed
Exigent Circumstance: Evanescent Evidence
evidence likely to disappear before warrant can be obtained
Exigent Circumstance: Emergency Aid
emergencies that threaten HEALTH or SAFETY if not immediately acted upon
Warrant Exception: Search Incident to Lawful Arrest
police may conduct a warrantless search incident to an arrest as long as it was made on probable cause
Warrant Exception: Search Incident to Lawful Arrest and Searching Cars
AFTER arresting occupant of a car, police can search INTERIOR of car incident to arrest IF:
- arrestee is unsecured and still may gain access to the interior of the car OR
- police reasonably believe evidence of the offense for which the person was arrested may be found in the vehicle
Warrant Exception: Search Incident to Lawful Arrest and Searching Phones
unanimous RILEY SCOTUS decision: warrantless search and seizure of the contents of a mobile phone incident to an arrest VIOLATES the Fourth Amendment
does not apply if a search of the phone is necessary either to protect officer safety or to preserve evidence
Balancing Test
Balancing Test For Searching Phone
court balances degree to which search incident to arrest INTRUDES upon a person’s privacy against the degree to which the search is needed to promote legitimate gov interests
Warrant Exception: Searches Incident to Impoundment
when officers impound a vehicle, they may conduct an inventory search of the vehicle EVEN WITHOUT PROBABLE CAUSE so long as the search is pursuant to police department policy
Arrest
= when police take a person into custody against her will for purposes of criminal prosecution or interrogation
- MUST be based on probable cause (based on totality of circumstances)
- do not need a warrant
Officer’s Knowledge Requirement for Arrest
officer must have knowledge of reasonably trustworthy facts and circumstances sufficient to warrant a reasonably prudent person to believe the suspect has committed a crime which arrest is authorized by law
Invalidating a Warrant
to invalidate warrant issued on the basis of a affidavit, claimant must prove:
- a false statement was included in the affidavit by the affiant
- the affiant intentionally or recklessly included that false statement AND
- the false statement was material to the finding of probable cause
Scope of Warrant
limited to what is reasonably necessary to discover the items described in the warrant
does NOT authorize police to search PERSONS found on the premises who are NOT NAMED in the warrant (can search those incident to arrest)
+ limited authority to detain occupants on the premises when the search is being conducted
Stop and Frisk
police have authority to briefly detain a person for investigative purposes EVEN IF THEY LACK PROBABLE CAUSE
must have reasonable suspicion supported by ARTICULABLE facts of criminal activity or involvement in a completed crime
may conduct a frisk to ensure there are no weapons
Frisk for Weapons
police can reach into the suspect’s clothing and seize any item that the officer reasonably believes, based on its “plain feel”, is a weapon or contraband
Executing Warrant
- only police can execute a warrant
- officer must knock and announce and wait for admittance for a reasonable time OR be refused admittance to use force to enter
When No Knock/ Announce Required
if officer has reasonable suspicion based on facts that knock/announce would be
dangerous or futile or
would inhibit the investigation
Detention: Obtaining Warrant
If police have probable cause to believe the suspect has hidden drugs in his house, they can prohibit him from going into the house unaccompanied to prevent him from destroying drugs while they obtain a warrant
Detention: Automobile Stops (Stop and Frisk)
stopping car = seizure for 4th amendment purposes
Police officers may NOT stop a car without reasonable suspicion the law has been violated
- can seize occupants or order occupants out
- may only search the areas in which a weapon might be placed or hidden AND the officer has reasonable belief that the occupant is dangerous
Confessions
to be admissible, DPC of 14th am requires confession is VOLUNTARY
Voluntariness of Confession
assed by totality of circumstances:
- suspects age/ education/ mental & physical condition AND
- setting/ duration/ manner of police interrogation
Involuntary Confession
product of threats/ coercion/ other duress
Interrogation
= express questioning or words and actions on the part of police that police should know are reasonably likely to elicit an incriminating response from the suspect
Spontaneous Statements
Miranda does not apply to spontaneous statements not made in response to interrogation
officers must give Miranda Warnings before asking follow-ups
5th Amendment Right Against Self-Incrimination
Miranda Warnings + valid waiver = prerequisites to admissibility of any statement made by the accused during custodial interrogation
A statement obtained through a custodial interrogation may not be used against a suspect in a criminal trial unless the suspect waives his right to remain and silent and right to counsel after being so informed by the police — officer must read the Miranda rights in full for any statements made thereafter to be admissible
Miranda Applicability
Anyone in police custody AND accused of a crime, no matter how minor, must be given Miranda warnings PRIOR to interrogation by the police
Detainee’s Rights After Read Miranda Rights
After receiving Miranda warnings, a detainee can:
1. do nothing
2. waive his rights
3. assert the right to remain silent OR
4. assert the right to consult with an attorney
Miranda - Doing Nothing
- court will not presume waiver of rights
- court will also not presume detainee has asserted right to remain silent or consult attorney [so police can continue to question]
Miranda - Waiving Rights
to be valid, gov must show by a preponderance of the evidence that the waiver was VOLUNTARY AND KNOWING, looking at totality of the circumstances
Miranda - Invoking Right to Remain Silent
invocation must be explicit, unambiguous, and unequivocal (mere refusal to speak is not enough)
What happens after invoking the right to remain silent?
- can be invoked at any time
- questioning related to that particular cirme must immediately stop and they must SCRUPULOUSLY HONOR the request (can’t badger)
- can reinitiate after, so long as they WAIT a significant time before reinitiating questioning (scrupulously honoring)
Custody
determining custody is a TWO-STEP inquiry:
- whether a reasonable person under the circumstances would feel that he was free to terminate the interrogation and leave AND
- whether the relevant environment presents the same inherently coercive pressures as the type of station house questioning at issue in Miranda
test depends on the OBJECTIVE circumstances of the interrogation
