Search Definition Test 2 Parts:

  1. Physical intrusion on protected area AND

  2. Intent to gather information

13
New cards

Mendenhall v. US (USSC 1980)

Case: DEA agents approached Mendenhall in an airport, asked for her identification and ticket, questioned her, and later obtained consent to search her, where heroin was found.

Holding: The Supreme Court ruled that no seizure occurred because a reasonable person in her situation would have felt free to leave, creating the “free to leave” test for determining a seizure under the Fourth Amendment.

30
New cards

Informational Probable Cause

  1. Officers don’t observe the crime often, we rely on given information

  2. Sources: dispatch, wanted notices, & APB

  1. consensual encounters

  2. investigatory stops

  3. arrests

32
New cards

Consensual Encounters

A brief, voluntary encounter between police & citizens where a reasonable person would feel like they are able to leave at any point (ex. Consensual walk & talk)

New cards

California v. Hordari D. (USSC 1991)

Case: Police officers chased Hodari after he ran from them, and during the pursuit, he threw away what appeared to be crack cocaine before being physically tackled and detained.

Holding: The Supreme Court held that a seizure does not occur unless police use physical force or a person submits to an officer’s show of authority, so Hodari was not seized when he discarded the drugs.

Why does it matter if he was seized?

  1. If he were seized, it would be unreasonable & the drugs would be inadmissible

  2. If he was not seized, the drugs were abandoned & lawfully recovered by law enforcement

38
New cards

Florida v. Bostick (USSC 1991)

Case: Police officers boarded a bus and asked Bostick for consent to search his luggage, where they found cocaine.

Holding: The Supreme Court held that a police encounter on a bus is not automatically a seizure, and the proper test is whether a reasonable person would feel free to decline the officers’ requests or otherwise terminate the encounter.

39
New cards

Drayton v. US (USSC 2002)

Case: Police officers boarded a bus during a drug interdiction effort and asked passengers, including Drayton, for consent to search their bags and persons, leading to the discovery of drugs.

Holding: The Supreme Court held that no seizure occurred because the officers did not use coercion or force, and passengers would have reasonably felt free to refuse consent or end the encounter.

40
New cards

Peters v. US (6th Circuit 1999)

Case: Federal officers arrested Peters without a warrant after suspecting he was involved in illegal activity and searched him incident to the arrest, finding incriminating evidence.

41
New cards

Investigative Detention

A compelled, brief, & investigatory stop

  • in appropriate circumstances & in an appropriate manner, an officer may approach a person & detain them for purpose of investigating possible criminal behavior even through PC has yet to be established

42
New cards

Terry v. Ohio (USSC 1968)

Case: A police officer observed Terry and another man repeatedly walking back and forth in front of a store and believed they were preparing to commit a robbery. The officer stopped them, conducted a quick pat-down for weapons, and discovered a handgun on Terry.

Holding: The Supreme Court held that officers may briefly detain a person and conduct a limited frisk for weapons without probable cause when they have reasonable, articulable suspicion that criminal activity is occurring and that the person may be armed and dangerous.

Two Principles that come from this case:

  1. frisk / pat-down (weapons only)

  2. reasonable suspicion

43
New cards

Using rationale from _____, an officer may detain an individual based upon the officer’s _________, _________ suspicion that criminal activity was being planned or was in the process of being executed.

Terry; reasonable; articulable

44
New cards

What are two considerations an officer should be mindful of when making a Terry stop?

  1. Use the least intrusive means of detention & investigation reasonably available that will achieve the goal

  2. Conduct the business of the stop as quickly as possible so as to not prolong the period of involuntary detention

    1. If, during the detention, additional facts are uncovered that supply the officer with probable cause to arrest, the individual may be arrested

    2. If grounds for an arrest are not discovered in a reasonable amount of time, the detainee must be released amount of time, the detainee must be released or the encounter risks becoming a de facto arrest

45
New cards

When courts review a claim of reasonable suspicion, they tend to place great weight on factors collateral to the suspect’s behavior. The more ______ present, the more likely ________ _________ will be found.

factors; reasonable; suspicion

46
New cards

_____-____ rules are not realistic. A determination of reasonable suspicion will depend on the specific ____ surrounding a particular stop & how those interplay with one another

bright-line; facts

47
New cards

What are the five factors used in determining totality of circumstances?

  1. Time & location (of day, crime scene, or escape route)

  2. High crime area (not sufficient by itself by USSC)

  3. Suspect’s criminal history

  4. Suspect’s demeanor & actions (nervousness & flight)

  5. Law enforcement & official sources (informants)

48
New cards

What two specific pieces of information must an informant provide law enforcement to be sufficient?

  1. information on the crime

  2. information on the suspect

49
New cards

The greater weight given to an identified informant is due to the _____ & the informants _________, the basis of their knowledge, & their motivation are more clearly evident.

facts; identity

50
New cards

Informant

someone who furnishes information for a reason other than being just a good citizen (ex. Immunity or lighter sentencing)

51
New cards

Are informants presumptively reliable?

No

52
New cards

What two considerations regarding anonymous tips will be considered part of the totality of circumstances?

  1. method of contact

  2. duration of contact

53
New cards

Aguiliar v. Texas (USSC 1964)

Case: Police obtained a search warrant based mainly on an informant’s tip that Aguilar possessed narcotics in his home. The affidavit, however, gave little information about how the informant knew this or why the informant was reliable.

Holding: The Supreme Court held that when using an informant’s tip to establish probable cause, officers must show both the informant’s basis of knowledge and the informant’s credibility or reliability, creating the two-pronged Aguilar test.

Two-pronged Aguiliar test:

  1. Reliability of the informant

  2. Reliability of the information (can overcome the informant)

54
New cards

Spinelli v. US (USSC 1969)

Case: The FBI used information from an informant, along with surveillance, to obtain a search warrant against Spinelli for illegal gambling activities.

Holding: The Supreme Court ruled that an informant’s tip alone is not enough for probable cause unless officers show the informant’s reliability/credibility and the basis of the informant’s knowledge, reinforcing the Aguilar two-prong test.

55
New cards

Gates v. Illinois (USSC 1983)

Case: Police received an anonymous letter claiming the Gates couple was trafficking drugs and used an independent investigation to verify parts of the tip before obtaining a search warrant.

Holding: The Supreme Court held that probable cause involving informants should be evaluated using the “totality of the circumstances” test rather than the strict Aguilar-Spinelli two-prong test.

56
New cards

Totality of circumstances test

A method of analysis where decisions are based on all available information rather than “bright-line” rules. Under the TOC test, courts focus “on all the circumstances of a particular case, rather than just one factor.”

Factors:

Conduct of the suspect

  1. Criminal or suspicious behavior

  2. Flight from officers

  3. Persons associated with known criminals are not a basis for arrest

57
New cards

Navarette v. California (USSC 2014)

Case: Police received a 911 call reporting that a specific truck had run the caller off the road, and officers stopped the vehicle and discovered marijuana inside.

Holding: The Supreme Court held that the anonymous 911 tip provided reasonable suspicion for the traffic stop because the report was sufficiently reliable under the totality of the circumstances.

58
New cards

What are the four permitted procedures for investigative stops?

  1. Requests for ID & questioning are the two most common techniques used during investigative stops

  2. Miranda warnings are not necessary because we haven’t established probable cause

  3. Subjects are not required to answer questions & their refusal to do so are not grounds for arrest (5th amendment violation)

  4. Subjects detained in a public place must provide their name, address, and date of birth if an officer reasonably suspects the subject…

    1. ORC 2921.29 Failure to Disclose Personal Information

59
New cards

What are the two NOT permitted procedures for investigative stops?

  1. Any significant movement of the subject

    1. Moving to a secondary location is permitted for a very few limited reasons (safety)

      1. If poor weather, take them a couple blocks up the road to better conditions (only short distance)

  2. Searching detainees for evidence or anything besides a weapon unless voluntary consent is given

60
New cards

Does the desire for officer safety supersede the requirements for a Terry frisk?

No. Under Terry v. Ohio, officer safety alone does not automatically justify a frisk. An officer must still have reasonable, articulable suspicion that the person is armed and dangerous before conducting a Terry frisk.

61
New cards

What are the two requirements that must be established before a Terry pat down/frisk is conducted?

Officers are required to articulate a reasonable belief that…

  1. The subject is armed AND

  2. The subject poses a threat to them

62
New cards

State v. Evans (OSC 1938)

Case: An officer stopped Evans for a traffic violation and conducted a pat-down after observing suspicious movements and concerns for officer safety, leading to the discovery of drugs.

Holding: The Ohio Supreme Court held that during a lawful traffic stop, officers may perform a protective frisk when they reasonably believe the suspect may be armed and dangerous, emphasizing officer safety during investigative detentions.

63
New cards

Plain Feel Doctrine

  1. While an officer may not search for objects other than weapons on a Terry stop, if the officer physically feels an object that the officer immediately recognizes as contraband, the object may be seized even if the officer knows it is not a weapon

    1. This only applies when the identity of the object is immediately apparent to the officer from its shape & the way it feels

    2. When the incriminating nature of the object is immediately apparent, seizing it does not invade the subject’s privacy beyond what is allowed in a Terry frisk

  2. The officer may not seize an object that, unmistakably, is not a weapon, or if determining its identity, requires further manipulation

    1. When determining if an object requires further manipulation (ex. Going into pockets, repeatedly squeezing the object), an additional invasion of privacy is necessary

    2. This action is not permitted during a Terry frisk

  3. Once it is determined that an object is not a weapon, the search must stop unless there is a warrant, probable cause for arrest, or consent

64
New cards

Terry Frisk of a Motor Vehicle

  1. Permitted to search the entire passenger compartment & any unlocked containers in which a weapon could be concealed

  2. Seize any weapons in plain view

  3. Seize any contraband, other than weapons, that the officer discovers during the course of the search for weapons

  4. Length of Duration

    1. No hard & fast rule

    2. Must not be longer than necessary to fulfill its purpose

    3. No more intrusive than needed to verify or dispel suspicions

    4. Officers must be able to justify the duration

    5. Unreasonably lengthy detentions turn into de facto arrests

65
New cards

Miranda Warnings

  1. When custody & interrogation are clearly present, Miranda must be advised

  2. Custody occurs when a reasonable person would feel that they are not free to leave

  3. Interrogation occurs when an officer asks investigative questions that the officer should know are reasonably likely to elicit an incriminating response

  4. When in doubt, read Miranda

  5. Miranda Requirements

66
New cards

For non-seizures with voluntary contact under a hunch, is Miranda required?

No

67
New cards

For a seizure from an investigatory stop with reasonable, articulable suspicion, is Miranda USUALLY required for interrogation?

No

68
New cards

For a seizure from an arrest with probable cause, is Miranda required for interrogation?

Yes
