Criminal Procedure Flashcards
Arrest
An arrest occurs when law enforcement officials place an individual into custody for interrogation or criminal prosecution against that individual’s will. Arrest requires law enforcement to have probable cause.
Law enforcement officials generally don’t need a warrant to arrest a person in a public place.
Search and Seizure
The 4th Amendment protects citizens against unreasonable search and seizures. The 4th Amendment is applicable to the states via the Due Process Clause of the 14th Amendment.
Government Conduct
For the defendant to assert a 4th Amendment right challenge, he must show government conduct. To establish government conduct, the defendant must show that the police were involved in the search and seizures.
Reasonable Expectation of Privacy
For the defendant to assert a 4th Amendment challenge, he must show a reasonable expectation of privacy. To establish it, the defendant must show that he had at least an ownership or possessory interest in the place searched or items seized.
Warrant requirement
For a search and seizure to be valid, the government must have acted pursuant to a valid warrant. If the warrant is not valid, or if the police did not have a warrant, all the evidence will be deemed inadmissible unless an exception to the warrant requirement applies
Exceptions to the warrant requirement
- Search incident to lawful arrest
- Hot pursuit
- Evanescent Evidence
- Consent
- Search incident to incarceration
- Stop and Frisk
- Plain View
- Automobile Exception
- Exigent Circumstances
Search incident to lawful arrest
Upon a lawful arrest based upon probable cause, the police may contemporaneously search a person and ares within his wingspan. The police may also make a protective sweep of the area if they believe accomplice may be present.
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.
Stop and Frisk
A police officer may stop a person without probable cause for arrest if the officer has an articulable and reasonable suspicion of criminal activity. If the officer reasonably believe the person may be armed and presently dangerous, the officer may conduct a protective frisk of the detainee’s outer clothing to search for weapons.
An officer may reach into the detainee’s clothing if the officer reasonably believe based on plain feel there is a weapon or contraband. But the officer cannot manipulate clothing to get a better feel of the item.
Plain View
The police may make a warrantless seizure when they:
- are legitimately on the premises,
- discover evidence, fruits, or instrumentalities of a crime, or contraband,
- see such evidence in plain view, and
- have probable cause to believe that the items is evidence, contraband, or a fruit or instrumentality of a crime.
Automobile exception
If a police have probable cause to believe that a vehicle is contraband or contains fruits, instrumentalities, or evidence of a crime, they may search the whole vehicle and any container that might reasonably contain the items for which they had probable cause to search.
Fruits of the Poisonous Tree
Generally, not only must illegally obtained evidence be excluded, but also all evidence obtained or derived from the exploitation of that evidence.
Valid Warrant
A valid warrant requires that it be issued:
- based on probable cause that seizable material or evidence can be found at the premises to be searched,
- by a neutral and detached magistrate, and
- with specificity regarding the place to be searched and items to be seized.
Incriminating Statements
The 5th Amendment guarantees a freedom against compelled self-incrimination. To protect this right, the Supreme Court requires police to inform detainees of their rights via Miranda warnings prior to any custodial interrogation.
Statements obtained without giving the warnings generally are inadmissible.
Custody
Determining whether custody exists is a 2 steps process:
- requires the court to determine whether a reasonable person, under the circumstances, would feel free to leave, Then,
- consider whether the environment presents the same inherently coercive pressures as the type of station house questioning at issue in Miranda.
