4th Amendment Flashcards
4th Amendment protects people from:
unreasonable searches and seizures
An arrest may be based upon:
Probable Cause
Arrest warrants are generally not required before arresting someone in a:
Public Place
- however, a non-emergency arrest of an individual in his home does require an arrest warrant
Station House Detention
The police need probable cause to arrest
you and compel you to come to the police station either for fingerprinting or interrogation
Investigatory Detentions are known as
Terry Stops
When can police briefly detain someone for investigatory purposes?
The police have the authority to briefly detain a person even if they lack probable cause to arrest. In order to make such a stop, the police must have a reasonable suspicon supported by articulable facts of criminal activity
- a hunch, even if accurate, is not enough
Reasonable Suspicion to do an investigatory stops hinges on:
The totality of the circumstances
Automobile Stops
The police may stop a car if they have at least reasonable suspicionthat the law has been violated.
Exception to Automobile Stops - when do the police not need reasonable suspicion?
Checkpoint roadblocks
- must be nuetrally applied
- For roadway safety(DUI checkpoints)
- or at border
Traffic Stops and Police Dogs
During routine traffic stops, a sniff is not a search so long as the police do not extend the stop beyond the time needed to issue a ticket or conduct normal inquiries.
- during such a traffic stop, a dog “alert” to the presence of drugs can form the basis for probable cause for a search
- police (without probable cause) cannot use a drug sniffing dog directly outside the home of a suspected drug dealer
Search & Seizure and your model for answering any search and seizure question: In 5 Steps
- Is there government conduct?
- Is there a reasonable expectation of privacy? (Standing)
- Did the police have a valid search warrant?
- If the warrant is not valid, does an officer’s Good Faith defense save the defective search warrant?
- Exceptions to the warrant requirement?
- If a warrant is invalid and cannot be saved by the good faith defense or if the police never had any warrant at all,then you move to last step: Exceptions to the warrant requirement:
Examples of government officials that could do government conduct
- publically paid police
- on or off duty
- Any private individual acting at the direction
of the public police.
Privately Paid Police
Privately paid police actions do NOT constitute
governmental conduct UNLESS they are deputized with power to arrest you
- Examples of Privately paid police
- (a) Store security guards
- (b) Subdivision police;
- (c) Campus police.
Automatic Categories of Standing:
- if you own the premises searched you always
have standing to object to the search of the place
you own. - You live on the premises searched, whether
you have ownership interest or not.- Example:Grandchild living at grandparents’ home.
- Overnight guests have standing to object
to the legality of the search of the place they are
staying.
An important “sometimes” category of standing:
You own the property seized
- If you own the property seized you have standing
only if you have a reasonable expectation of privacy
in the item or area searched
The “No Standing” Categories.
You have NO expectation of privacy, and therefore no standing for anything that you hold out publically everyday.The following is a list of things held out to the public, the seizure of which implicates no right of privacy:
- the sound of your voice
- the style of your handwriting
- the paint on the outside of your car
- account records held by a bank
- Monitoring the location of your car on
a public street or in your driveway.- installation of a GPS device on a
suspect’s car constitutes a search within the 4th amendment and thus requires probable cause and a warrant
- installation of a GPS device on a
- Anything that can be seen across open fields (The Open Fields Doctrine)
- Anything that can be seen from flying over in the public airspace
- The odors emanating from your luggage or car.
- Your garbage set out on the curb for collection.
- still have standing if set at side of house
Step 3: two core requirements for a facially valid search
warrant:
- probable cause
- particularity
Probable cause
a fair probability that contraband or evidence of a crime will be found in the area searched.
Particularity
The warrant must state with particularity the place to be searched and the things to be seized
Warrants and the Use of Informants
- If an officer’s affidavit or probable cause is based on informant information, its sufficiency is determined by the totality of the circumstances
- the informant’s credibility and basis of knowledge are all relevant factors in making this determination.
- A valid warrant can be based in part on an
informant’s tip even though that informant is anonymous- cannot be solely based on an anonymous tip
- must be corroborated
“No Knock” entry:
permitted in the execution of search warrants if exigent circumstances exist:
- An officer need not “knock and announce” if
knocking and announcing would be dangerous, futile or inhibit the investigation - Biggest fear of inhibiting the investigation: Destruction of the Evidence
Step Four: If the warrant is not valid, does an officer’s Good Faith defense sace the defective warrant?
The general rule is that an officer’s good faith reliance on a search warrant overcomes defects with the probable cause or particularity requirements.
Four exceptions to a good faith reliance on a
defective search warrant:
- The affidavit underlying that warrant is so lacking in PC that no reasonable police officer would have relied on it.
- The affidavit underlying that warrant is so lacking in Particularity that no reasonable police officer would have relied on it.
- The police officer or prosecutor lied to or mislead the magistrate when seeking the warrant
- If the magistrate is biased, and therefore has wholly abandoned his or her neutrality.
