Probable Cause, Exclusionary Rule, Ethics and Misconduct Flashcards
Definition of Probable Cause
a reasonable belief grounded on facts… must contain specific items associated with a crime… MUST BE SHOWN BEFORE AN ARREST WARRANT OR SEARCH WARRANT MAY BE ISSUED
In order to issue a search/arrest warrant, a magistrate must interpret an officer’s statement of probable cause in a _______ and ________ manner
Common sense and Realistic
Brinegar vs. US
Probabilities are not technical… they are factual and practical considerations of everyday life on which reasonable, prudent men act. THE STANDARD OF PROOF IS ACCORDINGLY CORRELATIVE TO WHAT MUST BE PROVED (THIS IS OFTEN SAID TO BE THE DEFINITION OF PROBABLY CAUSE).
District of Columbia vs. Wesby
DC Metro Police arrest 21 partiers in what was supposed to be a vacant home. Probable cause was brought into question afterwards.
When considering magistrate’s duty, what concept is basic to the concept of probable cause and its application to the legal system?
A judicial officer must make an independent judgment as to whether the 4th Amendment standard has been met.
For an arrest, there must be probable cause that…
- an offense has been committed
- the person to be arrested committed it
For a search, there must be probable cause that…
- An offense has been committed
- Certain items are connected to this criminal activity
- the items will presently be found in the place to be searched
(an affidavit containing facts to satisfy the probable cause requirement must be filed before a search warrant can be issued.)
U.S. vs. Ventresca
officers intruding on the privacy of citizens are well-advised to seek a disinterested determination of probable cause from an impartial magistrate because in “doubtful or marginal cases, a search under warrant may be sustainable where without one it would fail”… BASICALLY, GET A WARRANT JUST TO BE SAFE… THE OFFICER IS RESPONSIBLE FOR COLLECTING FACTS, AND THE MAGISTRATE MUST ASSESS THOSE FACTS’ SIGNIFICANCE IN THE EYES OF THE LAW.
State vs. Smith
mere conclusory statements which give a magistrate no basis to make a judgment regarding probably cause are insufficient to support the issuance of a search warrant… AFFIDAVIT MUST CONTAIN SUFFICIENT UNDERLYING FACTS AND INFO UPON WHICH A MAGISTRATE MAY MAKE A DETERMINATION OF PROBABLE CAUSE.
State vs. Weston
The existence of probable cause cannot be determined by simply counting the number of days between the occurrence of facts and the issue of a warrant
How does South Carolina require probable cause facts to be presented to a magistrate?
clear, concise, WRITTEN WRITTEN WRITTEN form
State vs. McKnight
The Constitution and the state of SC require search warrants to be supported by oath or affirmation… STATE LEGISLATURE ALSO STATED THAT SEARCH WARRANTS MAY ONLY BE ISSUED UPON AN AFFIDAVIT SWORN TO BEFORE THE MAGISTRATE. SWORN ORAL TESTIMONY ALONE IS NOT ENOUGH.
Sources of facts:
- firsthand
- witnessed by officer
- secondhand
ANY RELEVANT, LEGALLY OBTAINED EVIENCE MAY BE CONSIDERED ON THE ISSUE OF PROBABLE CAUSE EVEN THOUGH THE EVIDENCE MIGHT NOT BE COMPETENT PROOF AT TRIAL.
Personal Knowledge
facts an officer can testify as elements as probable cause… “I saw/heard/found”
Can a person’s assertion of their constitutional rights give an officer probable cause to believe that a crime has been committed/is being commited?
NO
Types of sources for Secondhand Information
- identifiable source
- good citizen informant (not a paid criminal informant)
- anonymous tip (requires additional corroboration to establish probable cause)
- confidential criminal informant (NOT NECESSARILY CONSIDERED TO BE TRUSTWORTHY)
State vs. Bellamy
The informant’s unreliability was compensated for by the strong showing of specificity, 1st-hand observations, and partial corroboration
Evaluating Informant information
- Two Pronged Test
- Totality of the Circumstance
Two Pronged Test… AGUILAR VS. TEXAS
determining if information info is sufficient to establish probable cause… underlying circumstances that show…
- how the source obtained the info in the case
- additional info to show source is a reliable-credible person
Totality of the Circumstances
ILLINOIS VS. GATES… totality of circumstances established, affording a magistrate broad discretion in determining probable cause.
MASSACHUSETTS VS. UPTON… confirmed totality of circumstances and rejected the separate requirement of the “two-pronged test”
What is the current test for the sufficiency of information?
Totality of Information Test or Totality of the Circumstances… source must have provided specific and detailed info that can be verified by independent law enforcement investigation… magistrate can use totality of information as their basis for the determination of probable cause
What is corroboration?
confirmation or support by additional evidence or authority… ABSOLUTELY NECESSARY…
- officer’s own reports and observations can be used
- “WEIGHT” OR PERSUASIVENESS OF INFO MUST BE CONSIDERED
- detailed info implies personal knowledge as is very meaningful
- greater weight is given to non-confidential info
