Kaplan Pgs 371-396 Fourth Amendment Flashcards
When a private party acts on his own and acquires evidence and then the government wants to introduce that evidence into a criminal prosecution, is that OK?
Yes, because no state actor was initially involved in getting the evidence
If a police officer demands that an airline employee inspect a passenger’s bag before a flight, is the fourth amendment triggered?
Yes, because that made the flight attendant’s actions public action
Is an arrest warrant required before someone is arrested in a public place?
No.
If an arrest is not an emergency and you are doing it in a person’s home, what is required?
A warrant
What is the two-step approach to determine if someone is in custody?
– whether a reasonable person would have felt that he was at liberty to terminate the interrogation. This is based on these factors: location of the questioning, duration, statements made during the interview, presence of physical restraints, release of the interviewee at the end of the questioning
- if the environment presents the same coercive pressures as a station house questioning would in Miranda
In order to determine if someone is in custody, whose mindset is considered?
Only a reasonable person in the suspect’s position. It doesn’t matter what the actual suspect thought or what the interrogating officers thought
Who can police officers strip search?
People who have been arrested for a crime
If you have been arrested, can police collect DNA from you?
Yes
What is needed to arrest someone?
Probable cause
From where can police get information in order to develop probable cause to arrest someone?
- their own observations (like witnessing a crime or observing behaviour prior to a stop)
– third parties (indirectly through an informant)
If police develop probable cause through information that came from an informant, what is required?
The informant’s tip had to have specific details, and those details must be reliable and confirmed before the moment of seizure
Police must have an arrest warrant before they can arrest someone in their own home, unless what?
The person consents or there are exigent circumstances
How do the requirements for an arrest warrant compare to those for a search warrant?
They are virtually the same
What would be considered an exigent circumstance that would allow a warrantless arrest in a person’s home?
- an arrest attempt was being made outside of the home but was thwarted because the suspect retreated into the house
– insufficient time to get a warrant and the delay would let the suspect evade arrest or destroy evidence
– the police were in hot pursuit and had probable cause to effect a valid arrest of the suspect
If police officers see the sale of drugs happen in front of a residence, and when the suspect sees the police officers he runs into the house with the drugs, can police follow the suspect into the house to arrest him without a warrant?
Yes, because they have probable cause and there is insufficient time to get a warrant before the suspect will destroy the evidence
If police violate the knock and announce rule, does that trigger exclusion of the evidence?
No
When must police officers knock and announce their identity before entering a house?
Anytime unless exigent circumstances exist (which includes a reasonable suspicion that knocking and announcing would be dangerous, futile, or would inhibit effective investigation)
When can an arresting officer break windows or other property?
If reasonably required to execute the warrant
When can a private citizen make an arrest?
For felonies committed in his presence
When can a police officer arrest a person without a warrant?
If he has reasonable grounds to believe that the person committed a felony
If a police officer did not personally observe a misdemeanour occur in his presence, can he arrest the person without an arrest warrant?
No
When can deadly force be used to prevent the escape of a felony suspect?
If the suspect poses a threat of serious physical harm to the officer or to others
When is probable cause evaluated?
Based on what was known at the moment of the intrusion
What is an anticipatory or conditional warrant?
A warrant that is conditioned on an event happening such as the delivery of a package
What are the two showings that must happen in order for a court to issue an anticipatory warrant?
- if the triggering condition happens, there must be a fair probability that evidence of the crime will be found at a particular location, and
– there must be probable cause that the triggering condition will occur
Can an anonymous tip alone give adequate information for probable cause?
No, but an anonymous tip coupled with police corroboration of some of the information can
What is a frisk?
A limited pat down of a suspect’s outer garments looking for weapons
If during a frisk for weapons, an officer feels an item that reasonably feels like a weapon or contraband, can he seize that item?
Yes
Is flight enough for probable cause or reasonable suspicion?
It is not enough for probable cause but it is enough for reasonable suspicion
What is required in order for information to be considered a reliable tip in order to give a reasonable suspicion?
The objective evidence requirement says that the information has to be confirmed as reliable before actually doing the stop. The tip has to contain some predictive information.
Ie: if a tip just says someone is standing by a payphone with a plaid jacket, that does not give reasonable suspicion because it has no predictive information
Does a passenger in an automobile have standing to challenge the validity of a search of the vehicle?
No, because he does not have any ownership or possessory interest in the vehicle
Would a passenger in a car have standing to challenge a police stop of the vehicle?
Yes, because all of the occupants of a car are seized during a traffic stop. This means that the passenger would have standing to challenge the search and seizure of items inside the vehicle as fruit.
Do overnight guests in another person’s home have standing?
Yes
Do short term guests, non-overnight social guests, and commercial guests have a reasonable expectation of privacy in a host home such that they would have standing?
No
What are things that a defendant does not have a reasonable expectation of privacy in even if they are held out to the public?
– handwriting exemplars
– voice exemplars
– bank records
– pen registers that record things like telephone numbers that have been dialed
– private conversations that have been eavesdropped on
If police use a drug dog to sniff for drugs on a person’s front porch, is that considered to be a search?
Yes
Do canine searches constitute fourth amendment violations?
Only if they physically intrude on a constitutionally protected area such as the home, curtilage, or person
Why are administrative searches OK to do without a warrant?
Because they are protecting airline passengers from weapons and explosives. If a passenger doesn’t want to be searched, he can decline to board the plane
Are drug sniffing dogs allowed to be used at a traffic stop?
Yes, as long as the prolongation of the stop is brief
A search done by government authority without a warrant is presumptively what?
Invalid unless a specially carved out exception applies
A reasonable search under the fourth amendment must be done according to what?
Either a warrant or an exception
If probable cause is illegally obtained, can that still support a search warrant or a warrantless search?
No
