Fourth Amendment Flashcards
Fourth Amendment
Fourth Amendment protects people from unreasonable searches and seizures
DOES NOT apply to searches and seizures by US officials in foreign countries and involving an alien
Arrests
Must be based on PROBABLE CAUSE
Warrant generally not required if arresting someone in a PUBLIC PLACE. BUT, non-emergency arrest of someone in his home REQUIRES an arrest warrant
“Seizure”
Totality of circumstances, a reasonable person would feel that the was not free to decline the officer’s requests or otherwise terminate the encounter
Probable cause
trustworthy facts or knowledge sufficient for a REASONABLE PERSON to believe that the suspect has committed or is committing a crime
Stop & Frisk (Terry Stops)
No need for probable cause. Police merely need REASONABLE SUSPICION (based on totality of circumstances) of criminal activity supported by ARTICULABLE FACTS (more than a hunch)
FRISK is justified only if officer reasonably thinks suspect has a weapon. Limited to patdown of outer clothing, unless officer has specific info that weapon is hidden in a particular area of suspect’s clothing. May extend to passenger compartment of vehicle if reasonable belief.
During patdown, officer may seize ANY item that officer reasonably believes, by its “PLAIN FEEL,” is a weapon or contraband, and admissible as evidence
Police must act in a DILIGENT and REASONABLE manner in confirming or dispelling their suspicions
Can be basis for other probable cause for arrest.
Automobile Stops generally
Police may stop a car if they have at least REASONABLE SUSPICION (totality of circumstances) that a law has been violated
Vehicle Checkpoint Roadblocks
No reasonable suspicion requirement. To be valid, must
(1) stop cars on the basis of some NEUTRAL, ARTICULABLE STANDARD (e.g. every car);
(2) be designed to serve purposes CLOSELY RELATED to a particular problem pertaining to automobiles and their mobility
Ex: drunk drivers valid b/c of drunk driving problem
Ex: Border checkpoints valid
Ex: illegal drungs NOT valid reason b/c purpose of checkpoint is only to detect evidence of criminal wrongdoings
Traffic Stops and Police Dogs
during routine traffic stops, a sniff is not a search so long as police do not extend the stop beyond time needed to issue a ticket or conduct normal inquiries
Dog ALERT can be the basis for PROBABLE CAUSE
NOTE: can’t use dog directly outside the home of a suspected drug dealer
Government Conduct
Step one of search & Seizure analysis
includes: (1) publicly paid police, on or off duty, and (2) any PRIVATE individual acting at the direction of the public police
Ex of Privately paid police: Store security guards, subdivision police, campus police
Expectation of Privacy
Government Conduct must reach into your reasonable expectation of privacy in place searched or item seized
Essentially standing to bring a 4th amendment challenge. Automatic standing if:
(1) you own the premises searched (always have standing)
(2) you live on the premises searched, whether owner or not (ex: grandchildren)
(3) overnight guests have standing to object ot legality of the search to the place they are staying
Personal Property: standing only if you have a reasonable expectation of privacy in the item or area searched
No Expectation of Privacy
No standing. No expectation of privacy in things you HOLD OUT TO THE PUBLIC. Ex:
(1) sound of your VOICE, (2) style of your HANDWRITING, (3) PAINT on the outside of your car, (4) account RECORDS held by a bank, (5) monitoring the LOCATION of your car (but note installation of GPS device constitutes a search and thus needs probable cause), (6) OPEN FIELD doctrine, (7) anything that can be seen from FLYING over the public airspace, (8) the ODORS emanating from your luggage or car, (9) your garbage set out on the CURB for collection
Search Warrant
Two requirements: probable cause and particularity
Must have search warrant unless if search falls under six exceptions
Must be issued by a neutral and detached magistrate (AG is not neutral)
Can get warrant to search third party premises, even if no evidence that suspect is there. Just need PC to believe evidence will be there
Probable cause for Search warrants
Warrant issued only if there is probable cause (FAIR POSSIBILITY) to believe that seizable evidence will be found on the person or premises at the time the warrant is executed
Informants for search warrants
Must meet “totality of circumstances” test
Takes into account informant’s credibility and basis of knowledge. Identity need not be revealed, anonymous is fine
Particularity
Warrant must state with particularity the PLACE TO BE SEARCHED and the THINGS TO BE SEIZED
