4th Amendment Flashcards
4th Amendment
protects from unreasonable searches and seizures and requires warrants to be based on probable cause
The 4th amendment applies ONLY to:
government conduct
What is a seizure?
When, due to government action, a reasonable person in the D’s position would not feel free to leave or terminate the police encounter. The police need to use physical force or a showing of authority followed by submission.
What is a terry stop?
brief investigatory seizure. Difference with arrest is the duration and purpose.
What is the permissible time for a terry stop?
The permissible duration is time necessary to confirm a reasonable suspicion that crime has occurred, if so, probable cause. If suspicion is denied, seizure must stop.
What is a search?
any government investigatory trespass against a 4th amendment interest OR intrusion into a reasonable expectation of privacy.
What is an investigatory trespass?
intrusion upon target’s, home (including cartilage), papers, or effects for purpose of finding or gathering evidence of a crime. Need investigatory motive.
A reasonable expectation of privacy requires:
1) D manifests subjective expectation of privacy by making effort to shield thing or activity from public
2) Expectation is objectionably reasonable because it is an expectation society is willing to recognize.
A search or seizure must be
reasonable
A warrant creates presumption of reasonableness, Defendant bears the burden of rebutting this presumption by proving:
1) warrant not based on PC
2) Magistrate not neutral or detached
3) warrant failed to describe with particularity thing to be seized or place to be searched
Any search or seizure without a warrant is presumptively
unreasonable and the government bears the burden of proving it falls within established exception
What is probable cause?
“fair probability,” facts and circumstances that would make a reasonable person conclude that the individual in question has committed a crime for an arrest or that specific items related to criminal activity can be found at a particular location.
What does the totality of the circumstances test for determining the reliability of tips consider?
1) veracity of the information
2) basis of knowledge
3) police investigation that corroborates facts in tip and validates accuracy of informant’s predictions.
What is reasonable suspicion?
a belief based upon articulable information more than a mere hunch used by a reasonable person or cop that suspect has or is about to engage in illegal or criminal activity
reasonable is a level of certainty that will justify only:
a brief investigatory seizure (Terry stop) or cursory protective search (Terry frisk)
What is required for an arrest?
1) probable cause is always required
2) Warrant is not required to arrest in public, but is required to arrest individual in own home unless exigent circumstances
What is required for a terry stop?
reasonable suspicion that crime is in progress or has just been committed justifies a brief investigatory seizure (terry stop) to confirm or rule out suspicion
How can reasonable suspicion be established for a terry stop?
1) police observations; eyewitness reports
2) flight from police in high crime areas
3) informant tip + police investigation that corroborates tip
What is required for a seizure of property?
a warrant based on PC presumptively, not always required to justify seizure of property
If in plain view:
No warrant required, instead:
1) police have a lawful vantage point to observe item
2) needs to be immediately apparent that item is contraband
3) officer has lawful access to point of seizure
Searches pursuant to a warrant
A warrant gives police authority to search only named places or people. Except: 1) contraband not named can be seized if in plain view; 2) right to detain occupants during search (but not right to search them.
Warrantless searches
Warrantless searches are per se unreasonable unless i t falls into an established exception.
What is a SILA?
Search Incident to Lawful Arrest: upon a lawful arrest (based on PC) can automatically search the arrestee + the area within his immediate control (wingspan or lunging distance)
SILA: arrest in or right out of car
1) can automatically search person
2) if genuine access to interior of car after arrest, can search interior car and all containers within interior
3) if no genuine access to interior of car, can only check car if reasonable belief evidence related to crime of arrest in car.
