Seizure generally
Fourth amendment provides that people should be free from unreasonable searches and seizures
Arrests are seizures so just needs to be reasonable
What is a seizure
Any exercise of control by a government agent over a person or thing
A seizure is when, under the totality of the circumstances, a reasonable person would feel that they were not free to decline the officer’s requests or otherwise terminate the encounter
When arrest occurs
An arrest occurs when the police take a person into custody against their will for purposes of criminal prosecution or interrogation
Definition of 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 totality of the circumstances
Requirements for an arrest
An arrest must be based on probable cause
A warrant generally is not required before arresting a person in a public place, but is needed for arresting someone in their home generally (unless exception)
Arrest in home
Need a warrant, unless exception
May enter the suspect’s home only if there is reason to believe the suspect is within it
Station house detentions
Police must have full probable cause for arrest to bring a suspect to the station for questioning or fingerprinting against the person’s will
Effect of invalid arrest
An unlawful arrest, by itself, has no impact on any subsequent criminal prosecution
Arrest with no probable cause, but later on does have probable cause, no problem that it originally was not there
Terry stops and frisks generally
The police have authority to briefly detain a person even if they lack probable cause to arrest
- brief detention for the purpose of investigating suspicious conduct
Can detain a person for investigative purposes if there is reasonable suspicion of criminal activity or involvement in a completed crime, supported by articulable facts
- not merely a hunch
Can also frisk for weapons if reasonable suspicion that the detainee is armed and dangerous
Reasonable suspicion definition
More than just vague suspicion, but less than probable cause
Whether the police have reasonable suspicion depends on the totality of the circumstances
Reasonable suspicion and informants
When reasonable suspicion is based on an informant’s tip, there must be an indicia of reliability, including predictive information
But predictive information does not have to be there to find it
Totality of the circumstances test - the informant’s reliability and credibility or their basis of knowledge are relevant factors in making the determination
Duration and scope of terry stops
Not subject to a specific time limit - must act in a diligent and reasonable manner in confirming or dispelling their suspicions
Detention can turn into an arrest if during the detention, other probable cause for arrest arises
Asking for identity during terry stops
The police may ask the detained person to identify themselves and generally may arrest the detainee for failure to comply with such a request
Property seizures - terry
Brief property seizures are similarly valid if based on reasonable suspicion
Automobile stops generally
Generally, police officers may stop a car if they have at least reasonable suspicion to believe that a law has been violated
Traffic stops and police dogs
During routine traffic stops, a dog sniff is not a search so long as the police do not extend the stop beyond the time needed to issue a ticket or conduct normal inquiries
Dog alert to the presence of drugs can form the basis for probable cause for a search
Police dogs and the home
Police, without probable cause, cannot use a drug sniffing dog outside the home of a suspected drug dealer
Mistake of law - terry stops
A police officer’s mistake of law (mistakenly believing that a vehicle must have two working brake lights) does not invalidate a seizure as long as the mistake was reasonable
