Title: Searches


1
Chapter 4
  • Searches

2
Fourth Amendment
  • The right of the people to be secure in their
    persons, houses, papers and effects, against
    unreasonable searches and seizures, shall not be
    violated, and no warrants shall issue, but upon
    probable cause, supported by oath or affirmation,
    and particularly describing the place to be
    searched , and the persons or things to be seized

3
Conditions of a Legal Search
  • A search warrant has been issued
  • Consent is given
  • An officer stops a suspicious person and believes
    the person may be armed
  • The search is incident to a lawful arrest
  • An emergency exists

4
Illinois v. Gates
  • The test for probable cause under the Fourth
    Amendment should be a totality of the
    circumstances test
  • This case modified Aguilar v. Texas, and Spinelli
    v. U.S.

5
A Search Warrant can be Issued for
  • Stolen or embezzled property
  • Property designed or intended for use in
    committing a crime
  • Property that indicates a crime has been
    committed or a particular person has committed a
    crime

6
Illinois v. McArthur
  • Police officers may detain residents outside
    their homes until a search warrant can be
    obtained if necessary
  • A police officers refusal to allow residents to
    enter their homes without a police officer until
    a search warrant was obtained was a reasonable
    seizure that did not violate the Fourth
    Amendment

7
Terry v. Ohio
  • The Terry decision established that a pat-down or
    frisk is a protective search for weapons and as
    such must be confined to a scope reasonably
    designed to discover guns, knives, clubs and
    other hidden instruments for the assault of a
    police officer or others
  • NOTE The officer may only pat-down for weapons

8
Florida v. J.L.
  • The Court held that police could not stop and
    frisk someone based on an anonymous tip

9
Chimel v. California
  • A search incidental to a lawful arrest must be
    made simultaneously with the arrest and must be
    confined to the area within the suspects
    immediate control
  • Immediate control means within the persons reach

10
Additional Cases
  • N.Y. v. Belton (1981) established that the
    vehicle of a person who has been arrested can be
    searched without a warrant. This search is
    limited to the passenger compartment and
    containers therein
  • N.Y. v. Quarles (1984) a warrantless search in
    the absence of a lawful arrest or consent is
    justified only in emergencies or exigent
    circumstances where probable cause exists and the
    search must be conducted immediately
  • Mincey v. AZ. (1978) the Fourth Amendment does
    not require police officers to delay a search if
    to do so would gravely endanger their lives or
    the lives of others

11
The Exclusionary Rule
  • The exclusionary rule established that courts may
    not accept evidence obtained by unreasonable
    search and seizure, regardless of its relevance
    to a case
  • Weeks v. U.S. (1914) made the rule applicable at
    the federal level Mapp v. Ohio (1961) made it
    applicable to all other courts

12
Related Principles
  • Fruit of the Poisonous Tree Doctrine established
    that evidence obtained as a result of an earlier
    illegality must be excluded from trial
  • Good Faith Doctrine established that illegally
    obtained evidence may be admissible if the police
    were not aware they were violating a suspects
    Fourth Amendment Rights

13
Goals of the Crime Scene Search
  • Establish that a crime was committed and what the
    specific crime was
  • Establish when the crime was committed
  • Identify who committed the crime
  • Explain how the crime was committed
  • Suggest why the crime was committed

14
Crime Scene Search
  • A true or uncontaminated crime scene is one that
    no evidence has been introduced into it or taken
    from it except by the person committing the crime
  • The elephant-in-a-matchbox doctrine requires
    that searchers consider the probable size and
    shape of evidence

15
Search Patterns
  • Exterior Searches
  • Lane Search Pattern
  • Strip Search Pattern
  • Grid Search Pattern
  • Circle Search Pattern

16
Search Patterns cont.
  • Zone/Sector Search Pattern
  • Interior Searches
  • Starts at point of entry
  • Floor first, then walls, then ceiling
  • Move clockwise or counterclockwise around room
    then search in opposite direction

17
Plain View Evidence
  • U.S. v. Henry (1958) Unconcealed evidence seen by
    an officer engaged in a lawful activity, is
    admissible in court
  • U.S. v. Lueck (1982)
  • Plain smell rationale

18
Other Types of Searches
  • Building Searches
  • Trash or Garbage Can Searches
  • Allowable if trash is accessible to the public
  • Restriction Curtilage-the portion of residence
    not open to the public
  • Vehicle Searches
  • Suspect Searches
  • Dead Body Searches
