The Fourth Amendment - Foundations of Search and Seizure
- Probable cause:
- justifies full custodial arrests and the absolute constitutional
prerequisite for a judge to issue a warrant to search a home or seize
property
- when the facts and circumstances within the officer’s knowledge are
sufficient to warrant a person of reasonable caution in the belief that
an offense has been or is being committed or that contraband will be
found in a particular place
Olmstead v. United States (1928) - Trespass Doctrine (later
overruled)
Fourth Amendment law was entirely tethered to English common law
property rights in physical trespass. The rule was remarkably rigid. It
was all about tangible things the government had to physically encroach
upon your property.
Situation
- During the Prohibition era, Roy Olmstead was suspected of operating
a massive, multimillion-dollar bootlegging ring.
- Federal agents tapped his home and office telephone lines to gather
incriminating evidence.
- The wiretaps were placed on the phone wires in public streets and
the basement of his office building, without ever physically
trespassing onto his actual property.
Ruling
Chief Justice William Howard Taft (textual and property based):
- Wiretapping was not a search because there was no trespass
- 4th Amendment protects persons, houses, papers and effects
- -> because there was no physical trespass, the 4th Amendment was
completely inapplicable
Katz v. United States (1967) - Reasonable Expectation of Privacy -
Phone Booth Case
As the 20th century progressed, that strict property based rule
really began to suffocate personal liberty. Parabolic listening devices
could pick up conversations through walls. The trespass doctrine left
citizens completely exposed to sophisticated electronic surveillance.
This overturned the previous Olmstead
doctrine.
Situation
- Charles Katz was suspected by the FBI of transmitting illegal
wagering information across state lines.
- Federal agents attached a listening and recording device to the
exterior of a public glass telephone booth that Katz frequented to make
his calls.
- The agents never physically penetrated the inside of the booth.
Based entirely on the recordings of his end of the conversations, Katz
was convicted of illegal gambling.
- Katz appealed, arguing that the warrantless
wiretap violated his Fourth Amendment rights.
Ruling
- Majority opinion by Justice Potter Stewart:
- “The 4th Amendment protects people, not places.” An
individual seeks to preserve as private, even in a space accessible to
the public, may be constitutionally protected.
- The Court reasoned that by stepping into the phone booth and closing
the door, Katz had a reasonable expectation that his conversation would
remain private.
- Attaching the listening and recording device was in fact a
constitutional search, despite the total absence of physical
trespass
- Concurring opinion - The Harlen 2 prong
test:
- The individual must have exhibited an actual
subjective expectation of privacy
- The expectation must be one that society is prepared
to recognized as objectively reasonable
- Dissent - Justice Hugo Black (an uncompromising textualist):
- the text of the 4th Amendment explicitly lists tangible things,
persons, houses, papers, and effects. It protects those tangible things
from physical search and physical seizure. (you cannot search a
conversation)
- Privacy literally does not appear anywhere in the 4th Amendment and
that elevating it to a constitutional standard was a dangerous act of
judicial overreach.
- Practical warning - how on earth do lawyers and judges know what
society finds objectively reasonable? it’s totally subjective.
California v. Greenwood (1988) - Trash case
Situation
- The Suspicions: Police suspected Billy Greenwood was dealing drugs
from his home in California, but they did not have enough evidence to
get a search warrant.
- The “Trash Pulls”: Investigators asked Greenwood’s regular trash
collector to pick up the garbage bags left on the curb and turn them
over directly to the police.
- The Warrants: Upon searching the garbage, police found items
indicative of narcotics use. They used this evidence to obtain a search
warrant for Greenwood’s house, where they discovered controlled
substances and made an arrest.
Ruling
- No Expectation of Privacy: The Court stated that an individual does
not have a “reasonable expectation of privacy” in garbage that is left
(abandoned) in a public area
- Public Accessibility: Because garbage bags placed on the street are
“readily accessible to animals, children, scavengers, snoops, and other
members of the public,” they cannot be considered private. Additionally,
the trash was placed on the street explicitly for a third party (the
sanitation department) to collect and take away.
Oliver v. United States (1984) - Open field (not curtilage)
Situation
- Narcotics officers went to Ray Oliver’s farm to investigate reports
of marijuana cultivation.
- They drove past his home, ignored a locked gate and
“No Trespassing” signs , and walked around a gate onto
a footpath.
- About a mile from his house, they found marijuana growing in a
field.
Ruling
- Unreasonable searches and seizures does not extend to open
fields
- An open field is not a person, a house, a paper and it is not an
effect.
- The Framers drafted the 4th Amendment to protect the
intimacies of the home, not vast expanses of rural
land
- Fences and no trespassing signs might give you civil trespassing
claim, but they DO NOT transform 100 acre forest into a constitutionally
protected area
Florida v. Jardines (2013) - Curtilage is Part of the Home
Situation
- The Tip: Miami-Dade police received an unverified tip that Joelis
Jardines was growing marijuana in his house.
- The Dog Sniff: Officers brought a drug-detection dog
up to Jardines’ front porch. The dog sniffed the base
of the front door and gave a positive alert for narcotics.
- The Arrest: Using this alert as evidence, officers obtained a search
warrant, discovered marijuana plants inside, and arrested Jardines.
Ruling
- The Supreme Court ruled that as unconstitutional search. The porch
is the curtilage.
- The government argued that anyone, a mail carrier, … a neighbor has
an implied license to walk up to the front door and knock. The police
argued they were just doing what any citizen could do.
- Justice Scalia: while a mail carrier has an implied license to walk
up and drop off a package, they absolutely DO NOT have an implied
license to bring a piece of highly trained forensic equipment (in this
case the drug dog) to conduct a physical investigation on
your doorstep.
United States v. Miller (1976) and Smith v. Maryland (1979) - Third
Party Doctrine
You lose your 4th Amendment expectation of privacy in any information
you voluntarily share with a 3rd party.
Situation
Ruling
- The Supreme Court held that bank customers have NO reasonable
expectation of privacy in their financial records because
they voluntarily share this information with their bank in the
ordinary course of business
- The Court ruled this was not a Fourth Amendment search because a
person voluntarily conveys dialing data to the phone company.
Carpenter v. United States (2018) - Exception to the Third Party
Doctrine - cellphone
Ruling
- Under strict mechanical application the Smith v. Maryland 3rd party
doctrine, the government would win easily.
- But Justice John Roberts (majority):
- applying the old doctrine to modern technology would functionally
destroy the 4th Amendment
- cell phone is no longer a luxury, it is almost a feature of human
anatomy. You cannot participate in modern society/economy without
one
- the phone pings towers automatically without any
affirmative act by the user
- differ from the CSLI from the bank records in Miller based on the
sheer volume, precision and inescapable
nature of modern digital tracking
- -> seizing 7 days or more of historical CSLI does violate a
reasonable expectation of privacy and therefore law enforcement must get
a warrant
United States v. Mendenhall
A person is seized only when, by means a physical force or show of
authority, their freedom of movement is restrained. e.g. Were the police
displaying weapons, were there multiple officers surrounding the suspect
in a physically threatening way? Did they retain the suspects ID or
plane ticket?
Illinois v. Gates (1983) - Totality of Circumstances
Gates Revolutionized how police departments use anonymous
informant tips to build probable cause. Before Gates, courts
relied on the strict Aguilar-Spinelli test, which required
search warrants based on informant tips to meet two rigid, independent
requirements:
- Basis of Knowledge: The informant must reveal how they
obtained their information.
- Veracity/Reliability: The police must establish why the
informant is credible or their information is reliable
(They have to prove this specific informant had a track record of being
truthful)
If you have a brilliant, incredibly detailed tip, but it was
completely anonymous, meaning you couldn’t prove the veracity of the
author, then the judge has to throw the whole tip away as it fails the
veracity/reliability test. The Supreme Court realized the rigid test was
tying the hands of law enforcement, so they threw out the 2 prong test
and adopted the totality of curcumstances.
Situation
- In May 1978, the Bloomingdale, Illinois, Police Department received
an anonymous handwritten letter. The letter alleged that Lance and Susan
Gates were drug dealers, describing in detail an operation where the
wife would drive their car to Florida, leave it to be loaded with drugs,
and the husband would fly down to drive it back.
- Police independently investigated these claims and verified several
key details. They found that Lance Gates had booked a flight to Florida,
stayed in a motel room registered to his wife, and was driving
northbound back toward Illinois on a major interstate used by
travelers.
- Police presented this corroborated information and the anonymous
letter to a judge, who issued a search warrant. Upon searching the
couple’s car and home, police discovered large quantities of marijuana,
weapons, and other contraband
Ruling
- The Court concluded that the letter writer was completely anonymous,
low veracity was overcome by the fact that the letter predicted future,
highly specific innocent travel behavior that the police independently
verified.
- A judge issuing a warrant must simply make a practical, common-sense
decision based on all the circumstances set forth in the affidavit
(including the “veracity” and “basis of knowledge” of the
informant).
- A deficiency in one of these areas can be compensated for by a
strong showing in the other, or by other reliable details discovered
during a police investigation.
Raucous v. Illinois - Constitutional Standing
Horton v. California (1990) - The Plain View Doctrine
Situation
- Police suspected Terry Brice Horton of an armed robbery and obtained
probable cause to search his home for the stolen property and the
robbers’ weapons. * However, the search warrant issued by the magistrate
only authorized a search for the stolen proceeds, not the weapons.
- During the authorized search, officers did not find the stolen
property but discovered the weapons in plain
view and seized them
Ruling
- lawful presence: the officer must be
constitutionally allowed to stand in the exact spot they are standing
whey they see the item.
- lawful right of access: they must have
legal path to physically reach the object
- immediately apparent: the incriminating
character of the object must be immediately apparent.
- it means the officer must have probable cause to believe the item is
contraband or evidence of a crime just by looking at it without
conducting any further physical manipulation or search.
- BH: remember Breaking Bad - “How could you have known that they
(the bullet holes) were there before you took off the tape?”
Review
- Step 1: Is it the
- government or
- private citizen acting as a directed agent?
- Step 2: Was there
- a physical trespass onto a protected effect to gather info under
United States v. Jones
- or a violation of a subjective expectation of privacy that is
objectively reasonable under Katz v. United States (The phone
booth case)
- Step 3: Did the search fall into categorical public exception?
- did they abandoned the property on the public curb like
California v. Greenwood? (The trash case)
- was it in a open field like California v. Greenwood or
within the protected curtilage like Florida v. Jardines?
- did they voluntarily share the data with a third party like
United States v. Miller or Smith v. Maryland?
- Step 4:If a person’s liberty is restricted, pinpoint the exact
moment of the seizure
- Apply the Mendenhall Free to leave test, but
- if they are running, apply Hodari D -> there is no seizure until
the physical force is applied or they actively submit to authority.
- Step 5: Does this specific defendant have a personal substantive
standing to complain about it?
- Were they an overnight guest with a recognized privacy interest
- or a casual afternoon visitor who gets no constitutional
protection?
