Criminal Procedure Flashcards
Constitutional Criminal Protections applicable to states
Through the 14th Amendment due process clause
Supreme Court has made a few rules: Miranda & Exclusionary
Fourth Amendment
Right to be free from unreasonable searches and seizures of person and property by the government
Applies when there has been a government intrusion in a constitutionally protected area or an area in which the defendant has a reasonable expectation of privacy
Government intrusion = police or citizens acting at request of police
A seizure is:
- Based on totality of the circumstances
- Reasonable person would not feel free to decline officer’s requests and terminate the encounter
Arrest
An arrest is a seizure
- must be based on probable cause; trustworthy facts/knowledge sufficient for reasonable person to believe suspect has committed or is committing a crime for which an arrest is authorized
Public arrest = no warrant requirement
Arrest at home = warrant is required
Probable Cause
Reasonable grounds to believe that a crime has been committed and that the arrestee has committed it
- Hunch is NOT probable cause
- If officer observes commission of crime = probable cause
- When police officer makes a non-emergency arrest of person in OWN home –> arrest warrant required
Terry Stops
If police have reasonable suspicion of criminal activity/involvement in a crime, supported by articulable facts they may detain a person in a reasonable manner for investigative purposes
Look for these magic words:
- Investigatory detention
- Reasonable suspicion
- Articulable facts
- Totality of circumstances
must be brief if goes longer, it will be an arrest
Roadblocks
- Cars must be stopped on a neutral, articulable standard; and
- Be designed to serve purposes clearly related to a particular problem relating to automobiles and their mobility
Automobile Stops
Must have at least reasonable suspicion to believe law has been violated (even if other basis)
- constitutes a seizure of any passengers as well
- passengers have standing to raise wrongful stop
Was search/seizure valid under 4th Amendment?
- Government conduct? - police and their agents
- Valid standing? - only if reasonable expectation of privacy
- Valid warrant?
- Any exceptions to warrant requirement?
Standing to raise 4th Amendment Violation
Reasonable expectation of privacy; determined by totality of circumstances
- Places owned by person
- Person’s home
- Place where they are staying as overnight guest
- Nonpublic areas in his place of business
No reasonable expectation of privacy in:
- things held out to public (voice/smell of luggage/car)
- open field
- garbage at curb
- someone else’s home/business/car/personal effects
*smells inside home are the only type of smell that is protected. by 4th amendment
Knock and Announce
Police generally must knock and announce authority
- No knock entry permissible if officer has reasonable suspicion that knocking and announcing would be dangerous/inhibit investigation
- Evidence not excluded based on violation of knock and announce
Valid Warrant
Based on probable cause AND particularity; must describe with particularity the place to be search and items to be seized
- Issued by neutral and detached magistrate
- Invalid if based on material false statement that was intentionally/recklessly included
- Police generally must knock and announce authority
- Police entitled to look anywhere that item they’re looking for could reasonably be found (fact specific)
Search of Persons Found On Premises
Warrant to search for contraband authorizes police to detain occupants of the premises during a search, but not to search persons who were not named in the warrant
Exceptions to the Warrant Requirement - If any of these, evidence admissible even if warrantless search:
If not within these, then warrantless search is unconstitutional.
- Search incident to lawful arrest (contemporaneous)
- Automobile exception
- Plain View
- Consent
- Stop and Frisk
- Hot pursuit of fleeing felon (police within 15 minutes of felon)
- Evanescent Evidence
- Emergency Aid Exception
- Inventory searches incident to arrest
- Public school searches by school officials
- Mandatory drug testing
- Border searches
*4th amendment is not violated by a statute authorizing a warrantless search of a parolee’s home- even absent probable cause - if a statute provides for such searches! Parolee’s have diminished expectation of privacy and government has heightened interest in searching parolees homes.
Automobile Exception
- Probable cause to believe vehicle contains contraband or fruits, instrumentalities, or evidence of a crime
- May search anywhere in/on car where item that is subject of search may be found
- Contemporaneous not required
-can take and search later
*can arise after car is stopped, but MUST arise before arrest
*watch out for differences w/ “search incident to lawful arrest”
Consent Entitles Warrantless Seizure when:
Someone with apparent right to use or occupy property consents
- If suspect is present, can overrule
- Parent usually has authority to consent to search of child’s room if parent has access to it
- Consent can come from anyone with an apparent equal right to use/occupy the property
- If co-occupant denies entry then police cannot come in
Examples:
Fraternity/Sorority House Example
- anyone who lives there can consent to areas they are entitled (not other person’s bedroom, unless has access)
Overnight Visitor
- consent is valid if it comes from anyone with APPARENT authority to give consent
Plain View Entitles Police to Make Warantless Seizure when:
- Police legitimately on premises
- Discover evidence, fruits, instrumentalities of contraband
- See evidence in plain view;
- Have probable cause to believe that the item is evidence, contraband, or a fruit/instrumentality of the crime
*Immediately Apparent Requirement: - police cannot manipulate item to determine if it’s contraband;
- has to be obvious upon immediately looking at it
Example: can’t turn over computer to verify serial #
Stop and Frisk
During valid Terry stop, if police have reasonable belief that detainee is armed and dangerous; may pat down outer clothing for weapons and may seize anything that by plain feel is weapon/contraband
Public school searches by school officials are valid if reasonable:
- offers moderate chance of finding evidence of wrongdoing;
- Implemented through means reasonably related to objectives of the search;
- Search not excessively intrusive
Emergency Aid Exception
Police officer may enter premises without warrant if officer faces an emergency that threatens health/safety of individual or public
Mandatory Drug Testing
Upheld when serves a special need beyond the needs of law enforcement
- High school students in extracurriculars
- Government employees with access to drugs

Violations of Sixth Amendment Right to Counsel
6th Amendment guarantees right to assistance of counsel in ALL criminal proceedings; all critical stages of prosecution after judicial proceedings have begun
*not applicable at pre-charge or investigative lineup
- Offense specific: pertains to only one crime and defendant must ask again if charged with separate, unrelated crime
- Waivable
- Statement made in violation of 6th Amendment not admissible to prove guilt, but can be used to impeach
Involuntary Confession / Violation of 14th Amendment
For self-incriminating statement to be admissible under due process clause –> must be voluntary
- Involuntary = official government compulsion
- harmless error test applies if involuntary confession erroneously admitted into evidence
- Totality of circumstances: age, education, setting, duration, abuse, etc.
- Torture of any kind makes confession involuntary
*lying to the defendant “I want to help you” –> does NOT make the confession involuntary
*If confession is involuntary, cannot be used to impeach!
5th Amendment Privilege Against Compelled Self-Incrimination = Miranda Warnings
- Right to remain silent
- Anything that is said may be used in court
- Right to an attorney
- If cannot afford attorney, will be appointed one
- must be given prior to custodial interrogation by police (doesn’t apply to informant or probation officer)
Custody Requirement for Miranda Warnings
- Whether a reasonable person under the circumstances would feel they were free to terminate the interrogation and leave?
- Whether environment presents the same inherently coercive pressures as type of station house questioning?
Two Common Ways Police Violate Miranda
- Failing to give appropriate warnings at the appropriate time
(before a custodial interrogation by police officer) - Failing to follow applicable rules after warnings have been given
Interrogation
Any police words or conduct designed to elicit an incriminating response
