unreasonable search/seizures Flashcards
3 things needed for a warrent
- particularity (particularly describing the place to be searched, the persons or things to be seized)
- reasonable execution
- probable cause
DC v. Wesby (2018)
Cant all the conduct be explained away innocently?
Key Question to ask for probable cause
whether a reasonable officer could conclude – considering all of the surrounding circumstances, including the plausibility of the explanation itself – that there was a substantial chance of criminal activity
Basis for arrest: unlawful entry
DC v. Wesby
Standard: knew or should have known entered without permission
Two things to look at when executing a warrent
- is it sufficiently particular? did the factual mistake invalidate the warrent?
- was the police conduct reasonable in executing the seach?
The place to be searched must be described in the warrant with
sufficient clarity that the officer executing it can identify it with reasonable effort
- Doesn’t have to be perfect and based on information known at the time presented to magistrate
If a mistake is made in executing a warrant, the Court will allow the evidence to be used if
the law enforcement mistake was objectively understandable and reasonable
does the 4th amendment warrent requirement require police officers to knock-and-announce prior to executing a warrent
yes, the police must knock and announce
exception to the requirement that the police must knock and announce when executing a warrent
“In order to justify a “no-knock” entry, the police
must have a reasonable suspicion that knocking and announcing their presence, under the particular circumstances, would be dangerous or futile, or that it would inhibit the effective investigation of the crime by, for example, allowing the destruction of evidence.”
Basic rules of applies when the
exigencies of the situation make the needs of law enforcement so compelling that a warrantless search is objectively reasonable
So what may constitute an exigent circumstance, allowing warrantless entry of a
home?
- Imminent harm to others
- a threat to the officer herself
- destruction of evidence
- escape from the home
- flight
Test in determining whether a situation is an exigent circumstance:
Under a totality of circumstances analysis – on a case-by-case basis - the delay required to obtain a warrant would bring about some real immediate and serious consequences
Extingent Circumstances always present in felony drug cases
Results in assumption that all felony drug crimes will involve
“an extremely high risk of serious if not deadly injury to the police as well as the potential for the disposal of drugs by the occupants prior to entry by the police”
Extingent circumstances must be
reasonable
For the exception of the extingent circumstances, the police officer must have a reasonable suspicion that knocking/announcing would be
dangerous, futile, or inhibit the effective investigation of crime
When is a Seizure Reasonable?
- Probable Cause
- Magistrate
(Arrest Warrent - so long as warrant is sufficiently descriptive (person) and reasonably executed)
Reasonable Seizure/Arrest
When is a Seizure Reasonable?
- Probable Cause
- Police
- No Arrest Warrant -arrest made in public
Reasonable Seizure/Arrest
When is a Seizure Reasonable?
- Probable Cause
- Police
- No Arrest Warrant -arrest made at home
unreasonable Seizure/Arrest
When is a Seizure Reasonable?
- Probable Cause
- Magistrate
- Search Warrant - so long as warrant is sufficiently descriptive (person/place to be searched) and reasonably executed
Reasonable Search
Probable cause relation to search/seizure
it helps make a search/seizure reasonable
- it can be determined by magistrate (when warrant is sought) or by judge (when police act under a warrantless search/seizure objection)
- is a totality of the circumstances analysis
What does a warrant require?
More probable cause and then warrants - particular description requirement, reasonableness in execution
Does the 4th Amendment forbid a warrentless arrest in the home, even if supported by probable cause
- No, to arrest an individual in his/her home, probable cause is not enough; instead, must have a warrant or an extingent circumstance
- “In terms that apply equally to seizures of property and to seizures of persons, the Fourth Amendment has drawn a firm line at the entrance of the house. Absent exigent circumstances, that threshold may not reasonably be crossed without a warrant”
2 requirements for getting an warrent
- Officers/Prosecutors must submit an “affidavit in Supoort of Search Warrant”
- “Probable cause must be determined by a neutral and detatched magistrate and not by the officer engaged in the often competitive enterprise of ferreting out crime.”
What is Probable Cause?
Probable cause exists where the facts and circumstances within the affiant’s knowledge and of which they have reasonably trustworthy information are sufficient in themselves to warrant a man of reasonable caution in the belief that:
- an offense has been committed by the person to be arrested; or
- evidence subject to search and seizure will be found in the place to be searched
Warrentless Searches and Seizures
Searches Incident to arrest
- Search of the Body – U.S. v. Robinson
- Search of the Home – Chimel v. California
- Search of the Vehicle – Arizona v. Gant
