Criminal Procedure Flashcards
Fourth Amendment- seizure of the person
People should be free from unreasonable searches and seizures. Any exercise of control by a government agent over a person or thing is a seizure.
Seizure
A seizure occurs, when under the totality of the circumstances, a reasonable person would feel that they were not free to decline the officer’s requests or otherwise terminate the encounter.
Arrest
Arrest occurs when the police take a person into custody against their will for purposes of criminal prosecution or interrogation. Arrests must be based on probable cause- trustworthy facts or knowledge sufficient for a reasonable person o believe that the suspect has committed or is committing a crime for which arrest is authorized by law.
Warrant not required unless arrest takes place in the person’s home.
Terry Stops
Police have the authority to briefly detain a person even if they lack probable cause to arrest. They need:
- reasonable suspicion of criminal activity or involvement in a completed crime (reasonable suspicion based on an informant’s tip must have indicia of reliability)
- supported by articulable facts
If they have a reasonable suspicion that the detainee is armed and dangerous they may frisk the detainee for weapons. They must act in a diligent and reasonable manner in confirming or dispelling their suspicions.
Automobile stops
Generally, police officers may stop a car if they have at least reasonable suspicion to believe that a law has been violated.
During traffic stops, a dog sniff is not a search, so long as the police do not extend the stop beyond the time needed to issue a ticker or conduct normal inquiries.
Automobile stop consistutes a seizure of all of the occupants.
Informational checkpoints and roadblocks
To be valid they must:
- stop cars on the basis of some neutral articulable standard
- be designed to serve purposes closely related to a particular problem relating to automobiles
Pretextual stops
If the police have probable cause to believe that a driver violated a traffic law, they can stop the car, even if their ulterior motive is to investigate a crime for which they lack sufficient cause to make a stop.
Fourth amendment- evidentiary search and seizure
Evidentiary searches and seizures must be reasonable to be valid under the fourth amendment but a warrant is required except in six circumstances.
- Was the search and seizure conducted by the government?
- Did the defendant have a reasonable expectation of privacy? Or was it a physical intrusion by the government into a constitutionally protected area?
- Did the police officers have a valid warrant?
- Or did a warrant exception apply?
Standing to object to governmental search
Person must have their own reasonable expectation of privacy with respect to the place searched or the item seized.
- person owned or had a right to possession of the place searched
- place searched was in fact their home
- person was an overnight guest of the owner of the place searched
Limits on Reasonable expectation of privacy
No reasonable expectation of privacy in objects held out to the public.
- sound of your voice
- style of handwriting
- paint on outside of car
- account records held by a bank
- location of car in public street or driveway
- anything that can be seen across open fields
- anything that can be seen from flying over public airspace
- odors emanating from luggage or car and
- garbage set out on the curb for collection
Police:
- cannot place a GPS tracker on a car without a warrant
- cannot use thermal imaging to see inside a home
There is a reasonable expectation of privacy in cell phone location records.
Requirements for a warrant
Probable cause + particularity (describes the place to be searched and items to be seized). Magistrate who issues the warrant must be neutral and detached.
Evidence obtained by police in reasonable reliance on a facially valid warrant may be used by the prosecution, despite an ultimate finding that the warrant was not supported by probable cause.
Search warrant based on an affidavit
A search warrant issued on the basis of an affidavit will be held invalid if the defendant establishes all three of the following:
- a false statement was included in the affidavit by officer applying for the warrant
- the affiant intentionally or recklessly included the false statement and
- the false statement was material to the finding of probable cause
All three must be present. Defendant is rarely successful in challenging the affidavit.
Execution of warrant
Only police can excute. Must be executed without unreasonable delay. Police must knock, announce their purpose, and wait a reasonable time for admittance unless officer has reasonable suspicion, based on facts, that announcing would be dangerous, futile or inhibit the investigation.
Police cannot be accompanied by third parties unless they are there to identify stolen property. Scope of search limited to what is reasonably necessary to discover the items described in the warrant.
The police cannot search persons on the premises who were not named in the warrant.
Exceptions to the warrant requirement
- search incident to constitutional arrest
- automobile exception
- plain view
- consent
- stop and frisk
- hot pursuit, evanescent evidence, and emergency aid
Warrant exceptions- search incident to constitutional arrest
If police make a valid arrest based on probable cause, they may search the person and areas into which they might reach to obtain weapons or destroy evidence.
Search must be contemporaneous in time and place with the arrest. But with automobiles, police may search the interior after securing a recent occupant in a squad car if they have reason to believe the vehicle contains evidence of a crime for which the recent occupant was arrested or they can search the passenger compartment if the arrestee is still unsecured and may gain access to the interior of the vehicle.
Warrant exceptions- automobile exception
If police have probable cause to believe that a vehicle contains fruits, instrumentalities, or evidence of a crime, they may search the whole vehicle and any container that might reasonable contain the item for which they had probable cause to search.
If a warrantless search of a vehicle is valid, they may tow the vehicle to the station and search it later. But if it is parked within the driveway of a suspect’s home, the police may not search the vehicle without a warrant.
Search may extend to packages belonging to a passenger of the vehicle.
Probable cause can arise after the car is stoped, but probable cause must arise before anything or anybody is searched.
Warrant exceptions- plain view
Police may make a warrantless seizure when they
- are legitimately on the premises
- discover evidence, fruits or instrumentalities of crime, or contraband
- see such evidence in plain view and
- have probable cause to believe (immediately apparent) that the item is evidence, contraband, or fruit or instrumentality of a crime
Warrant exceptions- consent
Warrantless search is valid if the police have a voluntary consent. Scope of search may be limited by the scope of the consent but generally extends to all areas to which a reasonable person under the circumstances would believe it extends.
Make sure the person has authority to consent. Homeowner can consent to search of their child’s room, but facts like the room was always locked and the parent could never get it in would indicate they do not have authority to consent.
Warrant exceptions- stop and frisk
Police officer can stop a person without probable cause for arrest if they have articulable and reasonable suspicion of criminal activity.
They can require the detainee to state their name and if they reasonably believe the person is armed and dangerous, they can conduct a protective frisk. This is limited to patdown of outer clothing unless officer has specific information that a weapon is hidden in a particular area of the suspect’s clothing.
Officer can reach into suspect’s clothing and seize any time that the officer reasonably believes, based on plain feel, is a weapon or contraband.
Warrant exceptions- Hot pursuit, evanescent evidence, and emergency aid
Evanescent evidence- evidence that might disappear quickly if the police took time to get a warrant. Ex: scraping underneath fingernails.
Hot pursuit- police in hot pursuit of a fleeing felon may make a warrantless search and seizure and may even pursue the suspect into a private dwelling. But if the fleeing person is suspected of a misdemeanor their flight does not always justify warrantless entry into a home. If police are not within 15 minutes behind a fleeing felon, it is not a hot pursuit.
Emergency aid- police officer may enter premises without a warrant if the officer faces an emergency that threatens the health or safety of an individual or the public.
