What is an arrest/when does it occur?
An arrest occurs when the police take a person into custody against their will for purposes of criminal prosecution or interrogation
Must be based on probable cause
Probable cause: trustworthy 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, based on the totality of the circumstances
Warrant generally not required for arresting in public place
But must generally have a warrant before arresting someone in their home
May only enter home if there is reason to believe the suspect is within it
Must also have full probable cause for arrest before bringing someone to the station for questioning or fingerprinting against the person’s will

Crim Pro
What is a Terry stop?
Police have authority to briefly detain a person even if they lack probable cause to arrest
If police have a reasonable suspicion of criminal activity or involvement in a completed crime, supported by articulable facts (more than a hunch), they may detain a person
If police also have reasonable suspicion that the detainee is armed and dangerous, they may frisk detainee for weapons
Reasonable suspicion: more than just a vague suspicion but less than probable cause, based on the totality of the circumstances
When reasonable suspicion is based on an informant’s tip, there must be an indicia of reliability to be sufficient (can include predictive info but doesn’t have to)
A Terry stop is not subject to a specific time limit
Police must act in diligent and reasonable manner in confirming or dispelling their suspicions
Police may ask the person to identify themselves and may arrest the detainee for failure to comply
Can turn into an arrest if during the detention, probable cause for arrest arises
Brief property seizures are valid if based on reasonable suspicion
Crim Pro
What are “articulable facts” in terms of Terry stops?
Articulable facts are far less than probable cause but more than a mere hunch - there must be something to go on - add up to reasonable suspicion, then probable cause
Police may briefly detain a person even if they lack probable cause to arrest, so long as they have a reasonable suspicion of criminal activity or involvement in a completed crime, supported by articulable facts
Crim Pro
When can an officer frisk someone for weapons during a Terry stop?
Terry stop is the brief detention when an officer has a reasonable suspicion based on articulable facts of criminal activity
If police also have reasonable suspicion that the detainee is armed and dangerous, they may frisk detainee for weapons
Crim Pro
What is “reasonable suspicion”?
More than a vague suspicion but less than probable cause, based on the totality of the circumstances
When reasonable suspicion is based on an informant’s tip, there must be an indicia of reliability to be sufficient (can include predictive info but doesn’t have to)
Crim Pro
What is the standard for when reasonable suspicion is based on an informant’s tip?
When reasonable suspicion is based on an informant’s tip, must be an indicia of reliability to be sufficient (can include predictive info but doesn’t have to)
Reasonable suspicion = more than vague suspicion but less than probable cause, based on totality of the circumstances
Crim Pro
Are Terry stops required to be a certain time limit?
No, they are not subject to a specific time limit
Police must act in a diligent and reasonable manner in confirming or dispelling their suspicions
Crim Pro
Can an officer arrest a detainee for not providing their name during a Terry stop?
Yes, police may ask the person to identify themselves and may arrest the detainee for failure to comply
Crim Pro
Can a Terry stop turn into an arrest?
Yes, although a Terry stop starts out as a brief detention based on reasonable suspicion supported by articulable facts - if they discover things so that probable cause arises, then they can arrest because arrests are based on probable cause
Crim Pro
Are brief property seizures valid during a Terry stop?
Yes, if they are based on a reasonable suspicion, like a normal Terry stop
Crim Pro
Can police make an automobile stop?
Yes, if they have at least reasonable suspicion to believe that a law has been violated
Crim Pro
During a routine traffic stop, can the police use dogs to sniff around?
Yes, during a routine traffic search, a dog sniff is not a search, as long as the police doesn’t prolong the stop for longer than is necessary to write a ticket, ask a few questions, etc.
If they prolong it, then that would be unreasonable and a search and would not be allowed without a warrant per the Fourth Amendment
A dog “alert” to the presence of drugs can form basis for probable cause for an actual search
Crim Pro
Does police’s mistake of law invalidate an automobile stop?
No, generally, police may stop a car if they have at least reasonable suspicion to believe that a law has been violated
Police’s mistake of law doesn’t invalidate that seizure as long as the mistake was reasonable
Crim Pro
Who is seized during an automobile stop?
The driver but also any passengers
This means passengers have standing to raise a wrongful stop as a reason to exclude evidence found during the stop
Crim Pro
Are informational roadblocks constitutional?
Yes, if set up for purposes other than seeking incriminating information about the drivers stopped
If special law enforcement needs are involved, police can set up roadblocks to stop cars without individualized suspicion that the driver violated some law
To be valid, roadblock must stop cars on the basis of some neutral, articulable standard (for ex: every car, or every other car - you’re not seeking out certain cars)
And be designed to serve purposes closely related to a particular problem pertaining to cars and their mobility (for ex: drunk driving)
Crim Pro
What are the two requirements for a valid informational roadblock?
A roadblock must stop cars on the basis of some neutral, articulable standard; and be designed to serve purpsoes closely related to a particular problem pertaining to cars and their mobility
