Fourth Amendment Flashcards
(63 cards)
What is a search?
First question you need to figure out to analyze if this is a search
Is this a Katz (expectation of privacy) analysis or a Jones (trespass) analysis?
What is a Search?
Jones / Physical trespass
Good ole fashion trespass to the things enumerated in the Fourth (persons, houses, paper, and effects) = search. Easy.
Jones = beeper on his car.
What is a search?
Dog sniffs
If you/your stuff is in a place where the cop/dog can lawfully be, the dog can sniff it.
- Airport = no problem (Place)
- Lawful traffic stop = no problem (Cabelles)
- Dog sniffing porch after no one answered doorbell = SEARCH (Jardines)
— Even though normal people can come up to porch (cartilage) and knock, having a doorbell doesn’t invite a canine forensic investigation. That’s a trespass, and therefore, is a search under Jones.
Two ways to argue that it wasn’t an unreasonable search
- Not a search
- Not unreasonable
What is a search?
Katz test
In Katz, the Court made clear that a physical trespass is not essential to a 4A search.
Rest:
1. Government upended someone’s actual (subjective) expectation of privacy
2. The expectation is one that society recognizes as “reasonable” (aka recognized by the majority of SCOTUS as reasonable)
What is a search?
Katz analysis: 4 major categories for analysis
- If any random citizen could have done it
- Third party doctrine
- Open fields doctrine
- Sense enhancing technology
What is a search
Katz analysis: if any random citizen could do it
Greenwood (trash on the curb)
Since any random citizen walking past could gave gone through the trash (it was abandoned property), cops can do it too. There is no expectation of privacy.
- Police are not expected to “avert their eyes” from publicly observable criminal activity
What is a search
Katz analysis: observing cartilage from the air
This falls in the Greenwood “if any random citizen could do it” theory.
Ciraolo (weed growing inside fenced cartilage)
- Even though the weed we within cartilage, that fact does not bar itself from public observation—anyone could have flown 1k ft above the house and saw it…
- The fact that one POV was blocked doesn’t prevent the officer to observe from a different vantage point he has the right to be.
Riley (greenhouse observed from 400 ft chopper)
- Court: helicopter was flying within FAA regulations, so anyone could have done it. No expectation of privacy if anyone could do it.
- Strongly suggesting that as long as pilots obey the law like FAA regulations, Katz will not prevent their observations
What is a search
Katz: Third party doctrine
Anything given knowingly to a third party does not have a reasonable expectation of privacy because the third party could have handed over your stuff. (Smith v. Maryland)
Exception:
- location data given to phone company… (Carpenter)
Court afraid of the slippery slope. Not getting rid of 3P doctrine. Just not going to apply it here since the consequences would be so great.
Allowing this would open the gates to all texts, emails, etc.
What is a search
Katz: Open fields doctrine
All “real property” is not protected by the Fourth. Only houses are enumerated. This includes the cartilage (area immediately surrounding and associated with the home), but not “open fields”
What is a search
Katz: Open fields doctrine
How to define curtilage
- Proximity to the home
- WAYYY more important than the rest of the factors (if you are far from the house, you lose (Dunn lost)) - Whether it is included within an enclosure
- Nature of use of area
- Steps taken by resident to protect the area from observation by people passing by
What is a search
Katz: Sense enhancing technology
COULD the information have been obtained without the use of the technology and without trespassing on [thing enumerated in 4A]?
- if yes = no reasonable expectation of privacy
Knotts beeper on meth ingredients to track car
- Public roads mean police could have totally tracked you with their eyes if they were better at their job.
- Why isn’t this a Jones trespass??
- - Beeper put in ingredient tub BEFORE it was knotts property so no trespass. - If no = definitely a search
- Using sense enhancing technology to obtain information that could not otherwise be obtained w/o intrusion into a constitutionally protected area is a search.
- at least where the technology is “not in general public use” (BT: what the hell does this mean though? prob just like “not weird” for someone to have it)
What does probable cause have to do with unreasonable searches?
Reasonableness generally requires obtaining a warrant. Obtaining a warrant requires probable cause.
Probable cause defined
Whether given the totality of the circumstances in the affidavit, there is a fair probability that contraband or evidence of a crime will be found in a particular place.
- Fair probability (doesn’t require an actual showing). Not a high bar.
Probable cause & the subjective opinions of officers
If there is actual probable cause, we won’t look at the actual subjective opinions officers.
So you can 100000% use probable cause on one crime to investigate another within reason.
- If you have PC that they are committing traffic violation, you can pull them over even if the real reason you want to pull them over is you think they have drugs.
Warrants and searches
SCOTUS has repeatedly stated that searches without a warrant are presumptively “unreasonable” and accordingly are presumptive violations of the Fourth Amendment
Warrants
Particularity requirement & why it matters
General warrants that do not specify the persons or things to be seized are prohibited by 4A.
- need some sort of specificity but don’t have to list exactly what it is.
This constrains where police may search.
- If searching for a stolen grand piano, police can look in any room, but can’t open drawers/cabinets (that would be unreasonable). If drugs were found when searching the cabinets that would be an unlawful search even though they had a warrant to search for the piano.
Warrant Execution
Knock & Announce
Common law knock & announce rule is part of conducting a “reasonable” search
- Exceptions:
a. Under circumstances presenting a threat of violence OR
b. Reason to believe evidence would likely be destroyed if advance notice were given
However, the fact that a certain type of investigation may frequently present these circumstances is not enough to dispense with K&A in every investigation of that type (no blanket exceptions). Fact & circumstance based decisions must be made each time.
Warrant execution
How long after knock & announce do police have to wait?
Depends on factors such as what the police seek, anticipated, dangerousness, etc.
US v. Banks found 15 seconds justified. Lower courts have approved shorter (CoMo 5 seconds)
- BT doesn’t think the time allotted provides sufficient time for people to get to the door without being in harms way
Warrant Execution
How must police treat persons present during the execution of a search warrant?
If a person is there (in house/curtilage), police can detain the person for the length of time that it takes to reasonably conduct the search, which is “surely less intrusive than the search itself”
Rationale/Justification
1. Preventing flight in the event incriminating evidence is found
2. Minimizing the risk of harm to the officers and
3. Facilitating the completion of the search (help unlock doors so we don’t have to knock them down)
Officers can then for sure ask detained person questions (they don’t have to answer)
BUT CAN’T
- Go grab you if you happen to have just left the scene before cops arrived
- Search the person detained absent separate reasonable suspicion required for Terry stop
- Arrest the person just for being present
Warrant Execution
Mistakes
Police don’t have to be perfect when executing. If officers made a reasonable mistake, it can still be a reasonable search.
Needs to be some sort of boneheaded unjustifiable mistake to be unreasonable.
Warrant exceptions list
- Plain view
- Automobile
- Search incident to lawful arrest (SILA)
- Consent
- Exigent circumstances
- Borders / points of entry
- Checkpoints
- Protective sweep
- Public school students & public employees
- Persons in Jail/Prison
- Probation / Parole
- Inventory searches of arrested persons
- Administrative searches
- DNA tests of arrested persons
Warrant exception
Plain view
Applies
(1) when incriminating evidence or contraband is discovered in a place where the officer has the lawful right to be (warrant, warrant exception, public place); and
- this means if warrant/warrant exception police need to be acting reasonable re: what they are searching for (think piano hypo)
- plain view exception doesn’t GET the police any place they otherwise can’t be.
(2) the officer has probable cause to believe the object is subject to seizure
- officer can’t pick up a stereo that looks like the one they know is stolen and flip it over (seize) to check if serial number matches.
Allows police to:
- Seize evidence in plain view without a warrant. Objects are subject to seizure if they are contraband or are otherwise evidence of, fruits of, or instrumentalities of a crime
Warrant exceptions
Plain feel?
If an officer feels seizable stuff during terry stop it works the exact same as plain view. Need probable cause that the thing felt was seizable (starfish hypo)
