Crim Pro Flashcards
exclusionary rule
- prevents introduction at a subsequent criminal trial of evidence unlawfully seized
- suppression decisions made by a judge; factual findings are reviewed for clear error while findings of law are reviewed de novo
government conduct
publicly paid police, private person directed by police, or deputized private police
arrest
unreasonable seizure of persons
seizure
when police, by means of physical force/show of authority, intend to terminate/restrain freedom of movement
analysis in determining seizure
totality of circumstances
- if police intent to restrain is ambiguous, or
- if def’s submission is only passive acquiescence:
then a seizure occurs if totality of circumstances would lead reasonable innocent person to believe he is not free to leave
stop and frisk
temporary detention that constitutes seizure if the officer, by means of physical force/show of authority, has in some way restrained (physical restraint or an order to stop) the liberty of a citizen
arrest warrant
must be issued by detached/neutral magistrate upon finding of probable cause and describe with particularity the def and crime
- deficient warrant does not invalidate arrest as long as there was PC (no warrant required for proper arrest based on PC)
search warrant
(i) issue by detached/neutral magistrate
(ii) upon finding of PC
(iii) supported by oath or affidavit
(iv) must describe with particularity places to be searched and items to be seized (reasonable belief that contraband will be found)
facts supporting probable cause for a warrant
- officer’s personal observations
- information from reliable, known informant or verified unknown informant
- evidence seized during stop and based on reasonable suspicion, discovered in plain view, or during consensual search
particularity for warrants
- must specify place to be searched and objects to be seized
- can also refer to contraband as “other fruits, instrumentalities, or evidence of crime at this time unknown” and still be valid
knock & announce rule
police must generally announce purpose when executing a warrant (unless state allows exception for exigent circumstances)
- violation does not trigger exclusionary rule
warrantless arrests
- warrant not needed in public place or for felony or misdemeanor in arresting party’s presence, but invalid arrest alone not a defense to crime charged (but will affect seizure of evidence)
- in determining whether a crime has been committed: whether an officer could conclude–considering all of the surrounding circumstances–that there was a substantial chance of criminal activity
reasonable expectation of privacy (REP) for home, private room, or office
home and curtilage, motel rooms, and business premises are protected; use of drug-sniffing dog is a search if physically intrudes onto constitutionally protected property
REP for luggage
luggage: REP for invasive searches but not canine sniff
automobiles (REP)
automobiles: need reasonable suspicion of law violation to effectuate a stop, and PC for pretextual stops when traffic law violated to investigate whether another law has been violated; fact that a person in lawful possession of a rental car is not listed on the rental agreement does not defeat his REP
open areas (REP)
outside curtilage–no reasonable expectation of privacy
odor from car (REP)
no REP
technological device (REP)
attaching a tracking device to a person without consent is a search; collecting cell-site location information from a wireless carrier to track a person requires a warrant
physically intruding on a suspect’s property to install a technological device may be a search
exceptions to search warrant requirement
incident to lawful arrest: must be reasonable in scope and incident to a lawful arrest
wingspan search
- must be reasonable in scope and incident to a lawful arrest
- includes contemporaneous search of person/immediate surrounding area including pockets/containers (does NOT include cell phone or laptop unless exigent circumstances exist)
home search
- must be reasonable in scope and incident to a lawful arrest
- “protective sweep” is permissible, even without PC or reasonable suspicion; includes immediately adjoining place of arrest in home from which an attack could be launched and in which a person might be hiding (adjacent rooms, closets, showers)
– search area can be broadened if based on reasonable suspicion that confederates are hiding beyond these immediately adjacent areas
vehicle search (incident to lawful arrest)
- arrestee is within reaching distance of passenger compartment (weapons/evidence) during search, or
- reasonable that evidence of the offense of arrest might be in vehicle
exigent circumstances
totality of circumstances test:
- must have PC and exigent circumstances
- police may not create the exigency by threats or conduct that violates 4A
hot pursuit
- police in pursuit of a suspect can seize “mere” evidence (not fruits/instrumentalities of crime) from a private building if they have PC to believe the suspect committed a felony
- may also act without warrant if they have PC that suspect committed a misdemeanor and the totality of the circumstances shows an emergency
emergency
reasonable apprehension that delay in getting warrant would result in immediate danger of evidence destruction, police/public safety or fleeing felon (judged by police officer’s objective reasonable belief)
stop (Terry stop)
reasonable suspicion (totality of circumstances), based on articulable facts that detainees involved in illegal activity, and is a limited/temporary intrusion on def’s freedom of movement
frisk
officer without PC may pat down a person’s outer clothing if the officer has reasonable suspicion that the suspect was/is involved in criminal activity and that the frisk is necessary for safety
“plain feel” exception
if officer conducting a valid frisk feels an object whose identity is immediately obvious (i.e., PC of contraband) it can be seized
passenger compartment search (during stop & frisk)
permitted if police have reasonable belief suspect is dangerous and may get immediate control of weapons, and the search is limited to places where a weapon could be hidden
limitations on stop & frisk
least intrusive means reasonably available to frisk for weapons only, but if suspicion becomes PC, then officer can make arrest and conduct a full search
automobile exception
can search any part of car (compartments, particular containers (including luggage), trunk, etc.) IF PC that it contains contraband/evidence of crime
does not permit warrantless entry of home or curtilage in order to search a vehicle therein
“plain-view” doctrine
in public view: no REP
in private view: officer on premises for lawful purpose, incriminating nature of item immediately apparent, officer has lawful access to item
consent
must be voluntary: no threats of harm, compulsion, or false assertion by lawful authority (totality of circumstances); but gov agent may pretend to be someone else
consent by third party
can consent to own property search, but def’s property only if agency relationship to def or def assumes the risk of search when giving right to third party to consent to search
