Crim pro Flashcards
Seizure
under the totality of the circum- stances, a reasonable person would feel that they were not free to decline the officer’s requests or otherwise terminate the encounter.
Arrest
An arrest occurs when the police take a person into custody against their will for purposes of criminal prosecution or inter- rogation.
An arrest must be based on probable cause
Terry Stop
police have the authority to briefly detain a person even if they lack probable cause to arrest. If the police have a reasonable suspicion of criminal activity or involvement in a completed crime, supported by articulable facts (that is, not merely a hunch), they may detain a person for investigative purposes
Reasonable suspicion
is more than just vague suspicion but is less than probable cause. Whether the police have reason- able suspicion depends on the totality of the circumstances.
Probable Cause
that is, trust- worthy facts or knowledge sufficient for a reasonable person to believe that the suspect has committed or is committing a crime for which arrest is authorized by law.
To be valid, the roadblock must:
Stop cars on the basis of some neutral, articulable stan- dard (for example, every car) and
Be designed to serve purposes closely related to a particular problem pertaining to automobiles and their mobility
Steps to analyzing search and seizure

FOURTH AMENDMENT— EXCEPTIONS TO THE WARRANT REQUIREMENT
SEARCH INCIDENT TO CONSTITUTIONAL ARREST
AUTOMOBILE EXCEPTION
PLAIN VIEW
Consent (a warrant negates consent)
HOT PURSUIT, EVANESCENT EVIDENCE, AND EMERGENCY AID
SEARCH INCIDENT TO CONSTITUTIONAL ARREST
Incident to a constitutional arrest (that is, one based on probable cause to believe a law has been violated and that meets other constitutional requirements),
the police may search the person and areas into which they might reach to obtain weapons or destroy evidence. The police may also make a protective sweep of the area if they believe accom- plices may be present.
SEARCH INCIDENT TO CONSTITUTIONAL ARREST (Automobiles)
The police may conduct a search of the passenger compartment of an automobile incident to arrest only if at the time of the search:
- The arrestee is unsecured and still may gain access to the interior of the vehicle; or
- The police reasonably believe that evidence of the offense for which the person was arrested may be found in the vehicle
AUTOMOBILE EXCEPTION
If the police have probable cause to believe that a vehicle contains fruits, instrumentalities, or evidence of a crime, they may search the whole vehicle and any container that might reasonably contain the item for which they had probable cause to search.
The probable cause necessary to justify the warrantless search of an auto under the automobile exception can arise after the car is stopped, but the probable cause must arise before anything or anybody is searched.
PLAIN VIEW
The police may make a warrantless seizure when they:
• Are legitimately on the premises
• Discover evidence, fruits or instrumentalities of crime, or
contraband
- See such evidence in plain view; and
- Have probable cause to believe (that is, it must be imme- diately apparent) that the item is evidence, contraband, or a fruit or instrumentality of crime
HOT PURSUIT, EVANESCENT EVIDENCE, AND EMERGENCY AID
Evanescent evidence is evidence that might disappear quickly if the police took the time to get a warrant.
Police in hot pursuit of a fleeing felon may make a warrant- less search and seizure and may even pursue the suspect into a private dwelling. If the police are not within 15 minutes behind the fleeing felon, it is not a hot pursuit that falls under the exception.
A police officer may enter premises without a warrant if the officer faces an emergency that threatens the health or safety of an individual or the public.
Public School Searches
A warrant or probable cause is not required for public school officials to search public school students or their posses- sions; only reasonable grounds for the search are necessary.
A school search will be held to be reasonable only if:
• It offers a moderate chance of finding evidence of wrongdoing
- The measures adopted to carry out the search are reasonably related to the objectives of the search; and
- The search is not excessively intrusive in light of the age and sex of the student and nature of the infraction
