Criminal Procedure Flashcards
Fruit of the poisonous tree
Evidence derived from primary tainted evidence; will also be excluded unless an exception applies
Exclusionary rule
Court-created remedy for violation of 4/5A. Will suppress evidence obtained in a violation of defendant’s 4/5A rights; applicable to states via 14A.
Note: does not apply to isolated negligence by LEO, “knock and announce violations,” or witness in-court identifications
Fruit of the poisonous tree exceptions
- Inevitable discovery: evidence would have been discovered whether or not the police acted unlawfully
- Independent source: discovered in part by a source unrelated to tainted evidence
- Attenuation: amount of time/events break the chain of causation from tainted evidence (“the taint dissipates”)
- Good-faith reliance on a facially valid warrant later struck down (objective standard)
Note: the state bears burden of showing exception applies.
4A
Protects persons from unwanted searches and seizures by the government.
- Governmental conduct: by law enforcement or an agent acting at law enforcement’s direction
- Reasonable expectation of privacy in the place searched/item seized
- Standing: can only assert own rights
Places where there is/isn’t a reasonable expectation of privacy
-
Yes:
- Home + curtilage
- Hotel room
- Another’s home if overnight guest
- Business premises
-
No:
- Objects held out to the public (voice, smell, plain sight)
- Garbage left on curb
- Exception: LEO had to intrude on private property to obtain information (e.g., affixing GPS to car)
Seizure of a person
- Occurs when the officer physically touches a subject or the subject submits to officer’s show of authority
- Test: a reasonable innocent person would not have felt free to decline officer’s requests or end the encounter
Note: police pursuit/car chase is not a seizure unless there is an intentional use of force (like forcing vehicle off the road)
Detention (Terry stop)
- Officer must have reasonable suspicion to investigate, supported by articulable facts
- “Hunch” will not suffice
- Detention must be brief, only long enough to verify or dispel suspicions giving rise to the stop
- For officer safety, may frisk D for weapons if he believes D may be armed
Arrest
- Officer must have probable cause to believe arrestee has committed a crime
-
Warrant required:
- Arrest at D’s home
- Arrest at another’s home, absent consent or exigent circumstances
-
No warrant required:
- Arrest in public AND
- Crime was committed in the officer’s presence OR
- Crime was committed outside the officer’s presence, but was a felony
Traffic stop
- Officer must have reasonable suspicion that a law has been violated
- Pretextual stops are OK
- Checkpoint stops (without reasonable suspicion) allowed if everyone is pulled over
-
During the stop:
- Driver and occupants may be ordered out of the car
- A frisk of driver/passengers for weapons is permissible if officer has reasonable suspicion they may be armed
- Limited search of passenger compartment for weapons is allowed
Searches
Rule: government must have a warrant supported by probable cause OR search must meet an exception
Probable cause
Knowledge of reasonably trustworthy facts and circumstances to believe…
- The arrestee has committed a crime (arrests)
- The items sought are fruits of a crime (searches)
Note: anonymous tip ≠ probable cause
Warrant requirements
- Supported by probable cause
- Issued by a neutral, unattached magistrate
- For searches: describes with particularity the place to be searched and the items to be seized
Warrant execution
- Must be executed by officer without unreasonable delay
- Knock and announce: officer must announce presence before entering, unless exigency applies
- Can detain, but not search, other individuals if they are in the immediate vicinity
Exceptions to warrant requirement (searches)
“ESCAPES”
- Exigent circumstances
- Search incident to arrest
- Consent
- Automobile exception
- Plain view
- Evidence from administrative search
- Stop and frisk
Exigent circumstances
- Officers are entitled to secure premises (prevent people from moving things or leaving)
- If in hot pursuit or there is immediate danger (including destruction of evidence) may conduct a search without warrant
- Does not apply when police created the exigency
Searches incident to arrest
-
General rule: Officers may make a contemporanous search in order to
- Protect officers from weapons or other dangers
- Prevent destruction or concealment of evidence
-
Scope:
- On the street: wingspan
- At home: suspect’s body and immediate surroundings
-
In car:
- Passenger compartment (not trunk) if arrestee is unsecured
- Entire vehicle if LEO has reason to believe that evidence related to the offense justifying arrest may be found in the car
- Cell phones: can seize and check phone for physical dangers, but need warrant to access digital information
- Inventory search: when police arrest a driver and impound his car, can conduct a routine inventory search
Consented to search
- Voluntary and intelligent waiver based on totality of circumstances
-
Jointly owned property: co-owner can consent if D is not present
- Physically-present D’s refusal will trump co-owner’s consent
- D cannot be moved to circumvent his refusal
-
Third party: can consent if has apparent authority over premises
- Landlords, hotel staff do not have apparent authority until D vacates
