Fourth Amendment Flashcards
Fourth Amendment (a)
The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated,
Fourth Amendment (b)
and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized
remedies when there is a 4th amendment violation
- application of the Exclusionary rule (where this does not apply then the civil remedies below do)
- Equal Protection violation of the 14th Amendment
- Ds can get relief from racially motivated prosecutions if they can demonstrate 1) that they were inentionally singled out for prosecution on the basis of race; and 2) that similarly situated person of a different race were not prosecuted
- section 1983 Civil Rights Act
*Civil suit if not arrested
application of the 4th amendment
applies only to searches and seizures conducted by government actors
Katz v. United States
(Katz test)
- the reasonable expectation of privacy test
- a person in a closed telephone booth does have an actual (subjective) and reasonable expectation of privacy such that the attachment of electronic eavesdropping devices on the exterior of the phone booth constitutes an impermissible search.
- Test:
- a person having exhibited an actual (subjective) expectation of privacy and
- that the expectation be one that society is prepared to recognize as reasonable
Purpose of 4th amendment
Limits discretion by government officials by requiring a signifcant degree of justification before police can intrude on the right of libery, privacy, and possessory rights
Where a defendant has no expectation of privacy
- a defendant has no expectation of privacy in things held out in public
- a defendant does not have a reasonable expectation of privacy in the following items, even if they are not held out in public
- Informants
- garbage
- bank records
- pen registers, which record telephone numbers dialed
- private conversations, including eavesdropping
- fields
- driveways for visitors and one might be a police officer
the setting in which the government action takes place is the most important factor in determining the existence of a “search”
- Open fields - unoccupied and undeveloped oopen areas have no 4th amendment protection
- curtilage- an area adjacent to and intimately connected with the home are protected
Oliver v. U. S.
Facts: 2 narcotic agents acting on reports, arrived on Oliver’s farm to investigate the growing of marijuana. There was a trespassing sign. A mile from Oliver’s house, the officers came across a crop of marijuana.
ROL: The framers did not intend the 4th Amend to extend to open fields when it stated a person shall be free on their persons, houses, papers, and effects. An individual may not legitimaely demand privacy for activities conducted outdoors, except in the area immediately surrounding the home
United States v. Dunn
Facts: Dunn owned a ranch which was completely encircled by a perimeter fence and which contained several interior fences. Outside of the resident fence were 2 barns which were encircled by fencing. Without a warrant, DEA agents crossed over the ranch’s perimeter fence and one interior fence. From direction of the barns, one of the agents smelled phenylacetic acid. The officer’s crossed over fence and looked into one of the barns and saw what he thought was a phenyl acetone laboratory. The officers left and returned with a search warrant. Search revealed chemicals, equipment, and amphetamines.
ROL: The barn was in an open field. 1st, the barn was not proximate to the house, 2nd, the bar was outside the fenced-in area surrounding the house, 3rd, the use to which the barn was put could not fairly be characterized as so associated with the activities and privacies of domestic life that the officers should have deemed the barn as part of respondents home and 4th, the steps taken by Dunn to protect the barn from observation by those standing in the open fields were minimal.
Dunn test (curtilate test)
- proximity
- enclosure
- uses
- steps taken to protect
- Note: only use these if not sure what the search fits into
*police officers do not engage in a search when they approach the front door of a residence and seek to engage in what is termed a “knock and talk”
Assumption of the risk
(search analysis)
engagement in conduct despite conscious awareness of the risk that certain informatino will not be kept private
Secret agent cases:
- there was no reasonable expectation of privacy when an informant reported his conversation with a Defendant to govt agents, or when govt agents overheard such a conversation transmitted by a radio device worn by informant
United States v. White
Facts: the govt wired an informant with a radio transmitter, as White and the informant convered, the govt listened in.
Held: One contemplating illegal activites must realize that his companions may be reporting to the police
United States v. Knotts
(electronic tracking devices)
Facts: officers installed a battery-opperated radio transmitter - a beeper- inside a 5-gallon container of chloroform. After receiving a tip, that a former employee had been stealing chemicals to make to make illegal drugs and was buying them from Hawkins Chemical Co. The officers Hawkins consent to install the beeper. When the former employee purchased the beeper planted container, the officers used video surveilance and monitored the beeper from a car then to a cabin. Relying on the beeper and additional information, the officers contained a search warrant, finding inside the cabin a drug laboratory.
Held: A person traveling in an automobile on public thoroughfares has no reasonable expectation of privacy in his movements, because those movements are open to the public
United States v. Karo
Beeper use had gone too far. The beeper had been used to reveal activities inside a private residence, a location not open to visual surveillance. That use invaded reasonable expectations of privacy, because even though visual surveillance was possible up t entry into the house, the beeper enabled the police to determine what they otherwise could not have known
United States v. Jones
(Global Positioning System (GPS))- trespass as search test
Facts: A task force attached a GPS to Jone’s vehicle in the course of a criminal narcotics investigation. The task force monitored the location of the vehicle for one month around the clock and eventually charged Jones for conspiracy to distribute cocaine.
Held: Attachment of a GPS device to the car was a 4th amendment search. Because the conduct of the task force would have been a common law trespass and such government trespass would have constituted a “search” at the time of the 4th amendment; and the court relied on reasonable expectation of privacy from long term monitoring
Kyllo v. United States
(Thermal Imaging Devices)
Facts: agents employed a thermal imager without a warrant to scan D’s home for infrared radiation emanating from the roof after receiving a tip that D was growing marijuana inside his home.
Held: a 4th amend. search takes place when govt agents employ a device that is not in general public use in order to explore details of a home that would previously have been unknowable without physical intrusion
container searches
(California v. Greenwood)
Facts: Police suspected D of narcotics trafficking, and they asked the neighborhood trash collector to pick up the plastic garbage bags that D left on the curb in front of his house and hand them over. An officer searched the bags, found items indicative of drug use, and then obtained a warrant.
Held: Plastic garbage bags on a public street are readily accessible to animals, children, scavengers, and snoops. This is assumption of the risk. The police could cannot reasonably be expected to turn their eyes from criminal activity that could have been observed by any member of the public
trunk search
requires probable cause to believe that fruits, contraband, or evidence of a crime will be found in the trunk
search at common law
trespass of a constitutionally protected area
- there is no search where police examine previously protected property in which an owner has voluntarily relinquished his or her proprietary interest
Social custom
(Minnesota v. Olsen)
facts: D was arrested in the home of two women with whom he was staying and claimed that the police violated his expectations of privacy when they entered and searched that home.
Held: D had a privacy interest in the premises because of his status as an “overnight guest.” Social custom- we seek temporary shelter. Officers are able to go to the guest house with the same arrest warrant as the original place.
Minnesota v. Carter
Facts: A cocaine transaction was observed by a police officer who peered through an apt’s window blinds. D had no connection to the apartment and had only been there just over 2 hours.
Held: a cocaine dealer who spent approximately two hours inteh apt of an acquaintance did not have a reasonable expectation of privacy
Illinois v. Caballes
Facts: 10 min traffic stop, 2nd officer walked dog around D’s car and searched the car after the dog alerted and found marijuana
Held: A drug dog sniff of a lawfully-seized car did not violate the 4th amendment. The drug dog sniff did not prolong the length of the lawful stop beyond what was justified by the traffic offense and the ordinary inquiries incident to such a stop
*the use of a drug-sniffing do at the entrance to a home is a “search” because it is engaging in a trespass, violating property rights and thus implicating the 4th amendment
Vantage Point
Permits police to stand in a certain public areas using enhancement devices, so long as those devices simply enable police to see more clearly something that they could otherwise see without the devices
*no reasonable expectation or privacy inheres in physical characteristics ordinarily observable by the public, such as the sound of a voice, physical appearance, and the characteristics of handwriting and fingerprints
Plain View Test
The police may seize property that is clearly visible in plain view without a warrant if the police are
- lawfully positioned and
- it is immediately apparent that the evidence is incriminating
Plain feel doctrine
Similar to plain view, but with feeling
Florida v. Jardines
Seizure
- Being told to do something and obeying
- touching
*need reasonable suspicion
Kinds of seizure
- arrest
- stop- you need “reasonable suspicion” to believe a person is committing a crime
- reasonable suspicion is less than probable cause
- suspicion that criminal activity is or will be afoot; its an objecttive test based on specific and articulable facts
Seizure
a seizure requires the deprivation of a constitutionally protected interest
- a seizure of a person occurs when a government actor significantly interferes with a person’s freedom of movement (arrest, or when the car is pulled over)
- a seizure of a thing occurs when the government significantly interferes with an individual’s possessory interests in that property
The Rakas Test
Rakas v. Illinois
A defendant whose rights are violated must establish standing to assert a 4th amend claim
- An ownership or possessory interest in the premises is sufficient (reasonable expectation of privacy in the area searched)
Facts: Passengers in a car, who did not claim to own the car and did not even claim to own the property seized did not have standing to object to the legality of the search simply because they were present at the time of the search.
Held: A passenger in an automobile lacks standing to challenge the validity of a search of the vehicle. The court considered whether the passengers had complete dominion and control over and the right to exclude others from those areas.
Standing
- Whether D was legally authorized to occupy the premises searched
- D has burden of proof
*no possessory interest in contraband
Government action requirement
- the search or seizure must have been accomplished by a government actor as opposed to a private party, in order to be considered illegal under the 4th Amend
- if a private individual conducts a search or seizure and subsequently reveals to law enforcement officials, evidence obtained during such a search or seizure, that evidence is admissible if offered by the govt
- degree of govt knowledge of participation in, the private person’s action, as well as the purpose of the private person are taken into consideration in deciding govt action
Skinnver v. Railway Labor Executives Ass’n
Facts: FRA promulgated regulations that authorized private railroads to take breath and urine samples from their employees for alcohol and drug testing purposes.
Held: When a private party acting on his own acquires evidence that the govt later seeks to introduce in a criminal prosecution, the 4th and the exclusionary rule are not triggered BUT when a private party acts at the direction of the govt agent or pursuant to an official policy, any search conducted and evidence seized is subject to 4th amend.
*even where a private individual has acted without the encouragement, endorsement, and participation” of the government, the 4th Amendment might be implicated if the later govt conduct intrudes further on the aggrieved aprty’s 4th amendment interests than the private party’s conduct
Probable Cause (required for search, seizure, and arrest)
quantity of facts and circumstances within the police officer’s knowledge that would warrant a reasonble person to 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 (for a search)
Maryland v. Pringle
Facts: Officer stopped speeding car at 3am. The officer saw money in the glove compartment when the driver went to retrieve his license and registration. The driver, denied having weapons or narcotics and consented to a search. There were 5 bags of cocaine found inteh back-seat armrest. None of the men admitted ownership of the drugs or money and were then arrested and taken in. D waived his miranda rights and gave confessions.
Held: Probable cause is evaluated in terms of what was known at the moment of the government intrusion. Police may establish Probable cause by considering events leading up to the moment of arrest to decide whether, viewed from the standpoint of an objectively reasonable police officer they amount to probable cause.
How much suspicion do you need?
Probable cause (less than 50%)
- if police don’t know a crime has been committed then it would be mroe than 50 %
- if the police know there has been a crime committed but they just don’t know who then it would be a little less
Ybarra v. Illinois
Facts: Police executing a warrant to search a tavern and its bartender evidence of possesion of a controlled substance conducted pat down searches of all the customers present, and seized six packes containing heroin from a cigarette pack retrieved from Ybarra.
Held: The search was invalid. It was based on insufficiently individualized suspicion as to Ybarra and mere propinquity to others independently suspected of criminal activity does not, without more, give rise to probable cause to search that person.
An arresting officer acts appropriately if he makes an arrest
- based on a valid warrant obtained by another officer who had probable cause for the warrant or
- based on orders from an officer who had probable cause
requirement of probable cuase
requires individual suspicion-suspicion that this suspect is guilty of a crime or that this place harbors contraband, fruits, evidence, or instrumentalities of crime
Aguilar-Spinelli Two Pronged test
- Was the informant credible (was he likely telling the truth?)
- was the informant reliable (was it likely that he had a sound basis of knowledge?)
*if police testimony failed to establish either prong, the tip could not be used in the probable cause determination
*evidence hearsay rule protects credibility and reliablity
Credibility/Veracity prong
- whether the tip was against interest, whether it implicated the informant in criminal activity ( Fed. Evi. Rule 803(b)(3) excepts from the hear say rule, a statement which at the time of its making so far tended to subject the declarant to criminal liability that a reasonable person in the declarant’s position would not have made the statement unless believing it to be true)
- Whether the informant had given prior accurate tips
- whether the informant had a reputation for truthfulness
*ex. Police officer, citizen with nothing to lose and no reason to lie, informant who has given info on previous occasions
Basis of knowlege Prong
- whether the informant personally observed or participated in the activities reported in teh tip
- whether the tip was so detailed that the informant must have first-hand knowledge
- whether the nature of the information contained in the tip, or the manner in which it was gathered, indicate that it could have come only from personal knowledge or a highly reliable source
*if weak in this prong, officer can use corroborating evidence
The Gates Test (Illinois v. Gates)
Facts: Respondents were indicted for violation of state drug laws after police officers, executing a search warrant, discovered marijuana and other contraband in their automobile andhome. The Police Dept received an anonymous handwritten letter.
Held: Relevant considerations in the totality of the circumstances analysis traditionally has guided probable cause determinations: a deficiency in one may be compensated for, in determining the overall reliability of a tip, by a strong showing as to the other, or by some other indicia of reliability. The totality of circumstances analysis, permits a balanced assessment of the relative weights of all the various indicia of reliability attending an informant’s tip.
*officer found future corroboration with the letter, future corroboration is more important because it shows that the basis of knowledge is stronger, not everyone will be able to find out
*no warrant to search if there is consent
Arrest
- Must be reasonable (the authority of arrest is given by statute)
- probable cause is always required
Atwater v. City of Lago Vista
Facts: Police officer arrested Atwater for violating a TX law mandating the use of seatbelts for children and passengers in the front seat.
Held: When officers have probable cause to believe that a person has committed a crime in their presence, the 4th Amend permits them to make an arrest, and to search the suspect in order to safeguard the evidence and ensure their own safety. 4th amend permits warrant/warrantless arrests for traffic misdemeanors committed in police officers presence.
The requirement of an arrest warrant
- governed by the location on the action
- if the arrest is in a public place, the police can arrest without a warrant, so long as they have probable cause
- if the arrest or seizure takes place in a place protected by the 4th amend, a warrant is required
- if D’s home, only arrest warrant necessary
- if 3rd part home or premises, the police must have a search warrant as well as arrest warrant to protect the privacy expectation of 3rd party
- the warrant requirement is excused in exigent circumstances; the 4th amend does not require police officers to delay in the course of an investigation if to do so would gravely endanger their lives or the lives of others
Use of force
- if making any arrest, with or without a warrant, the arresting officer may be required to use force if the suspect resists
- the force used must be reasonable since its a seizure
- requies careful attention to the facts and circumstances of each particular case, including the severity of the crime at issue, whether the suspect poses an immediate threat to safety of the officers or others, and whether he is actively resisting arrest or attempting to evade arrest by flight
Tennesee v. Garner
Facts: The officers were dispatched to answer a “prowler inside” call. The officer asked the yourth to halt, but when Garner tried to climb over a fense, the officer shot Garner, who later died. The officer was sure that Garner was unarmed but feared Garner’s escape.
Held: Where the suspect poses no immediae threat to the officer and no threat to others, the harm resulting from failing to apprehend him does not justify the use of deadly force to do so.
California v. Hodari
Held: a fleeing suspect has not been seized unless he stops, either because he is physically forced to do so or because he submits to an officer’s show of authority; if an officer shoots at an individual and misses, the 4th amend does not apply becasue the person was not seized
Scott v. Harris
Facts: Speeder did not slow down when Scott flashed his lights. Scott applied his push bumper to the rear of respondent’s vehicle causing it to veer off the road and crash at the bottom of an embankment. As a result Harris was rendered quadriplegic from the injuries suffered.
Held: Law enforcement may, consistent with the 4th amend reasonableness, take actions that place a fleeing motorists at risk of serious injury or death in order to prvent that flight from endangering the lives of innocent bystanders
Escalating force
- officers should use no more force than is necessary or reasonable, or that force should be used only as a last resort
- police use force to affect civilian’s conduct, they do so most often by employing the least degree of force available to them, their mere presence
- when officers’ mere presence fails to produce desire conduct police resort to verbalization
- when officers do speak they are asked to do so persuasively
- the next step up is command voice
- next step is the firm grip in which the officer grips parts of the body that let their subject know that an officer is present and that he/she wants the subject to remain still or to move in a certain direction but that does not cause pain
- pain compliance consists of grips designed to gain subjects submission by inflicting pain without causing lasting physical injury
- impact techniques involve actual physical contact or the use of chemical sprays or stunning electronic weapons designed to overcome resistance that is forcible, but less than imminently life-threatening
Stop and Frisk
(Terry v. Ohio)
Facts: While an officer was patrolling in plain clothes his attention was attracted by two men.
Held: If a police officer reasonably believes, based upon the officer’s own observations or those of an informant, that criminal activity may be afoot, then the officer may stop and briefly question a criminal suspect. In order to frisk a stopped individual, the police must articulate reasonable suspicion that the suspect is armed and dangerous. If the stop and frisk give rise to probable cause to believe that the suspect has committed a crime, then the police should be empowered to make a formal arrest, and a full incident search of the person.
Stop
Need “reasonable suspicion” to believe a person is committing a crime
- a brief on the scene detention that is strictly limited in time (ex. temporary detention of a pulled over car)
Frisk
a form of search
- need reasonable suspicion in the circumstances to believe that the person is armed and dangerous; poses a threat to the officer or some other person in the area
- a pat-down for weapons on the outer clothing, limited in scope and intensity to its justification
- once inside the clothing it is a search
- can also frisk an area if the officer has reasonable suspicion that a person within the area is armed and dangerous
- can have consent
*cannot frisk without stopping but can stop without frisking
Interaction levels between individual and law enforcement
- voluntary “encounter” the individual is free to leave without answering any questions and in whcih no 4th amend search or seizure occurs
- “stop and frisk” the individual, for a brief period, is not free to terminate the encounter
- “arrest” where the invasion of an individual’s freedom is so intrusive that probable cause is required as justification; and it evolves into a full search where the invasion of privacy is so great that probable casue is demanded
United States v. Mendenhall
Facts: Mendenhall had been approached by federal agents as she walked through an airport concourse. The agents identified themselves, requested her identification and airline ticket, and asked her some questions about herself.
Held: A person has been seized within the meaning of the 4th Amend only if, in view of all of the circumstances surround the incident, a reasonable person would have believed tht he was not free to leave. Mendenhall was not seized because the event took place in a public place, the officers did not wear uniforms and displayed no weapons. The requested but not demanded her identification
Circumstances giving rise to a reasonable belief that one is not free to leave: (Mendenhall factors)
- The threatening presence of several officers
- the display of a weapon by an officer
- some physical touching of the person of the citizen or
- the use of language or tone of voice indicating that complaince with the officer’s request might be compelled
Florida v. Bostick
Facts: Florida Cnty had a practice of routinely boarding buses at scheduled stops and asking passengers for permission to search their luggage. Passengers on buses are not ordinarily free to leave. Two officers, with badges, holding a recognizable zipper pouch, containg a pistol boarded a bus. The officers picked out D and asked to inspect his ticet and identification. The 2 officers persisted and explained their presence as narcotic agents. They then requested the Ds consent to search his luggage. The police advised that D had the right to refuse consent though he disputes that knowledge. At no time did the officers threaten D with a gun. After the consent cocaine was found.
Held: The appropriate test of seizure is whether sucha person would feel free to decline the officer’s requests or terminate the encounter. The presence of inquisitive officers ona bus does not necessarily create 4th amend seizure.
United States v. Drayton
Facts: 3 officers questioned passengers on a bus. Their weapons were concealed. The officers asked Ds if they had any bags and they pointed to a green bag which revealed nothing. The officer noticed Ds clothing being big for the warm weather. The officer asked Ds to check their person, they both consented. The officer detected hard objects between their thigh, which turned out to be packages of drugs.
Held: The “free to terminate” test necessitates a consideration of all of the circumstances surround thei encounter. There was no application of force, no intimidating movement, no overwhelming show of force, no brandishing of weapons, no blocking exits, no threat, no command, not even an authoritative tone of voice. Not suppressed because Ds consented.
Arizona v. Johnson
Facts: Police ordered Johnson, a passenger in a lawfully stopped vehicle, out of the car and conducted a Terry frisk upon his person.
Held: . For the “frisk” test, the police had to have reasonable suspicion that the person frisked was herself armed and dangerous. 1) an officer’s inquiries into matters unrelated to the reason for the stop do not convert the encounter into something other than a lawful seizure, so long as such inquiries do not appreciably extend the stop’s duration.; 2) no new justification was needed for such inquiries, at least on the facts before the Court.
Hiibel v. Nevada
Facts: A deputy sheriff had been dispatched to investigate a telephone call by someone who reported seeing a man assault a woman in a red and silver truck. The man asked the officer why he wanted to see his identification. After 11 requests for identification and the passage of several mins, and after warning the man that he would be arrested if he continued to refuse to comply, the officer did arrest him.
Held: A police officer is justified in requesting a suspect’s name as identification during a Terry stop as long as the request has an immediate relation to the purpose of the stop. Terry may permit an officer to determine a suspect’s identity by compelling the suspect to submit to fingerprinting only if there is “a reasonable basis for believing that fingerprinting will establish or negate the suspect’s connection to that crime.
Brendlin v. California
Stop v. Arrest
- Terry stops must be brief, and they must be conducted at the scene of the stopo
- once the individual is detained for a considerable length of time or removed to another location, a reviewing court is likely to hold that the encounter escalated to an arrest
- 20 min detention is a terry stop but if 90 minutes its deemed to long and the detention is deemed to have ripened into a full blown seizue and no longer amenable to a terry justification
Place of detention
- Pennsylvania v. Mimms
- Officers are permitted to order drivers out of their vehicles after Terry traffic stops, as a matter of public safety
- Maryland v. Wilson
- Passengers may be ordere out as well but detentions that move beyond the immediate vicinity of the stop are likely to be considered arrests
- Florida v. Royer
- Royer was taken from an airport concourse to about 40 ft away. Suspects forcibly taken to police headquarters will undoubtly be viewed as having been arrested
- Kaupp v. Texas
- Forcible transportation to police headquarters constitutes an arrest and requires probable cause or judicial authorization to be legal. 17 you awaken at 3 in the moring by 3 officers that stated “we need to go and talk”
United States v. Arvizu
Facts: The agent justified the terry stop of a minivan on the basis of a number of facts that he claimed gave rise to reasonable suspicion to beliee that the occupants of the van were trafficking in drugs.
Held: Reviewing courts must look to the totality of the circumstances of each case to see whether the detaining officer has a particularized and objective basis for suspecting legal wrongdoing. An agent is entiteld to make an assessment of the situation in light of his specialized training and familiarity with the customs of the area’s inhabitants
Illinois v. Wardlow (exception to Terry’s free to leave standard=High crime area)
Facts: Police on narcotics patrol had conducted a Terry stop of Wardlow after he looked in their direction and fled. The officers frisked Wardlow and found a gun and Wardlow later was prosecuted and convicted for unlawful use of the weapon.
Held: Nervous or evasive behavior is a relevant consideration, and flight is the consummate act of evasion. Sudden flight from a high-crime area may be an adequate reasonable suspicion for an investigative stop
Anonymous tip under Terry standard
- anonymous tip may be sufficient to support a finding of reasonable suspicion that a crime was in progress or was about to be committed
- reliability will be enhanced by the tipster’s obvious eyewitness perspective
- an anonymous tip that lacks all indicia of reliability does not satisfy the reasonable suspicion standard and would warrant no police response or require further investigation before a forcile stop of a suspect would be authorized
Florida v. J. L.
Facts: Police had conducted the Terry stop of J.L., a juvenile after an anonymous caller informed them that a young black male standing at a particular bus stop and wearing a plaid shirt was carrying a gun. Police arrived at the bus stop and observed 3 black males. The police notice nothing suspicious about the individuals, but based on the tip stopped and frisked J.L, finding a gun.
Held: The anonymous tip lacked sufficient indicia of reliability to give rise to reasonable suspicion. The holding would not preclude a stop and frisk if police receive a man with a gun tip from a known informant.
Drug Carrier Profiles
(Reid v. Georgia)
Facts: The petitioner arrived at the airport on a commercial airline flight from FL. The Petitioner was observed by an agent of the DEA, who was in the airport for the pourpose of uncovering illicit commerce in narcotics. Separated from the petitioner by several people was another man, who carried a shoulder bag like the one petitioner carried. The men left the terminal together. DEA agent asked them to show their tickets and identification.
Held: the agent could not as a matter of law, have reasonably suspected the petitioner of criminal activity on the basis of these observed circumstances. Nor could the manner in which the petitioner and his companion walked through the airport reasonably could have led the agent to suspect them of wrongdoing.
United States v. Sokolow
Held: The stop was justified because Sokolow was making a quick round trip to a drug source city, had paid for his tickets in cash, had checked no baggage, and appeared nervous.
*Courts reviewing Terry stops cannot rely exclusively on the fact that an individual matched a profile, but they may defer to accumulated law enforcement experience, embodied in profiles when they evaluate for themselves the suspiciousness of certain behaviors and characteristics that form the asserted basis for the stop
