Principles of Law Enforcement
  • Chapter 13
  • Police and the Law

2
Student Objectives
  • Acquaint the students with the amount and type
    crime in the U.S. and types arrests made by the
    police
  • Learn the role of the Bill of Rights and the
    U.S Supreme Ct in regulating the actions of
    police
  • Explain the role of the police in making arrests,
    search people and places, and stopping automobiles

3
Objectives Cont..
  • To familiarize students with the changing
    philosophy of the Supreme Court in areas of
    search and seizure, custodial interrogation, and
    identification procedures
  • Familiarize students with current standard
    police procedures using examples of case law in
    areas of search and seizure, custodial
    interrogation, and identification procedures

4
Introduction
  • This chapter is perhaps the most important one in
    the text. The role of the police is a very
    special one in our society. The police do much
    more than enforce the law and make arrests but
    police power is what comes to mind when we think
    of the police. When police arrest people they
    take away a persons freedom and liberty. The
    police must know the law and apply it correctly.

5
Crime in the U.S.
  • Crime is part of life in the United States
  • We see crime on TV and we read about it daily in
    our newspapers
  • Crime is measured by two major methods
  • Uniform Crime Report
  • National Crime Victimization Survey
  • Both plan to make significant changes

6
Uniform Crime Reports
  • The UCR is published annually by the FBI based on
    crimes reported to the police across the U.S.
  • The publication Crime in the United States has
    4 sections
  • Crime Index
  • Crime Index Offenses Cleared
  • Persons Arrested
  • Law Enforcement Personnel

7
UCR Cont..
  • The Crime Index consists of the FBI part 1 crimes
    which are the seven most serious crimes
  • Murder, Non-negligent manslaughter, Rape,
    Robbery, Aggravated Assault, Burglary, Larceny
    Theft, and Motor Vehicle Theft
  • Prior to 1972 it was the only major crime source
    but people had concerns about crimes that were
    not reported to the police

8
National Crime Victimization Survey
  • The NCVS is prepared by the institute of justice
    which is the research arm of the Dept of Justice
  • Here a survey is conducted covering a six month
    period by surveying persons door to door to find
    out if anyone in the household was a victim of a
    crime
  • Questions are asked about the incident and the
    information is published yearly

The Police and the Constitution
  • The primary law regulating life is the U.S is the
    Constitution
  • We now want to look at the Bill of Rights, the
    14th Amendment, and the role of the Constitution
    in regulating the police
  • And look at the exclusionary rule

12
Bill of Rights and the 14th Amendment
  • The 1st 10 amendments are known as the Bill of
    Rights
  • Five of the first ten amendments address the
    freedoms or rights people possess when involved
    with the criminal justice system
  • The 1st , 4th, 5th, 6th, and 8th were amendments
    were ratified in 1791
  • The 14th came in 1868

13
Bill of Rights and the 14th Cont
  • The Bill of Rights were the direct result of
    oppression of the people in England before they
    came and settle in America
  • The 14th had a major affect on the US Criminal
    Justice System because it extended the Bill of
    Rights to the states

14
14th Amendment
No citizen can be denied life, liberty, or
property without due process of law in both
Federal and State Jurisdictions
15
Role of the US Supreme Court in Regulating the
Police
  • Through its policy of judicial review the
    Supreme Ct has had a significant impact on police
    procedures as they have developed over the years

16
Role of the Supreme Ct Cont..
  • 1914 Weeks v U.S. -Brought about changes in
    search and seizures
  • 1936 Brown v Mississippi Ruled certain methods
    of police interrogation were unconstitutional
  • Rights of the individual vs the Rights of Society
  • Example You (rights of society) want a safe
    classroom but a classmate (rights of the
    individual) brings a gun to school

17
Balance of Rights
  • The Supreme Court has always had conflicting
    goals when weighing the rights of society vs the
    individual
  • If we give society too many rights we give up our
    individual liberties
  • If we give individuals too many rights our
    society will not be safe from crime

18
Exclusionary Rule
  • It is not part of the constitution
  • It holds based on the 14th amendment that any
    evidence seized in violation of the constitution
    cannot be used in a court of law against a
    defendant
  • Since 1914 the Supreme Court has been concerned
    with the use of illegal means by which police
    obtain evidence

19
Exclusionary Rule Cont..
  • At first the Exclusionary Rule only applied to
    Federal Agents and officers
  • The court continually warned the states to comply
    until 1961 when they applied the exclusionary
    rule to state courts

20
Four Supreme Cases that Shaped Police Policy
  • 1914 Weeks vs U.S.- Agents entered the home
    without a warrant and seized evidence. The
    Supreme Ct overturned the conviction and
    established the exclusionary rule
  • 1949 Wolf vs Colorado- Wolf was an abortionists
    and his appointment book was seized w/o a warrant
    whereas clients told on him. Wolf was convicted
    and later released. By then 31 states had
    rejected the exclusionary rule

21
Four Supreme Cases that Shaped Police Policy
Cont..
  • 1952 Rochin vs California- Police raided Rochins
    home w/o a warrant. Upon seeing him place illegal
    narcotics in his mouth they forcefully tied to
    extract evidence from his mouth. After an
    unsuccessful attempt they went to the hospital
    and forcefully pumped his stomach and recovered
    the capsules. Case was overturned and the supreme
    court sent out another warning

22
Four Supreme Cases that Shaped Police Policy
Cont..
  • Mapp vs Ohio 1961- Again police used a
    warrantless entry to enter a womans home and
    search for a man linked to a bombing.
  • While in her home police found obscene
    materials and arrested and convicted Ms Mapp
  • The Supreme Court had enough and imposed the
    Exclusionary Rule on all state courts

23
Is it Fair?
  • Many police officers and citizens feel the
    exclusionary rule is unfair
  • They feel it is procriminal and antipolice
  • They feel it allows hardened criminals a chance
    to escape in a technicality
  • Actually the Exclusionary Rule is used more on
    drug offenses and not violent crimes

24
The Police and Arrest
  • The power of the police is restricted by the 4th
    and 5th amendments
  • You cannot deprive citizens their right to life,
    liberty, or property w/o due process of law
  • Arrests can be made with or without a warrant or
    when directed to do so by a judicial officer

25
The Police and Arrest
  • Police can arrest for crimes committed in their
    presence
  • Felony crimes if they have P.C. to believe a
    crime has occurred
  • Under the authority of an arrest warrant

26
Probable Cause
  • Most arrests are made by officers on the street
    without a warrant because once they become aware
    that a crime has been committed, it necessitates
    immediately action
  • Most arrest are made by the probable cause
    standard
  • Probable cause is defined as evidence that may
    lead a reasonable person to believe that a crime
    has been or is about to be committed
  • It is less than beyond a reasonable doubt

27
Reasonable Force in Making Arrests
  • The amount of force an officer can use when
    making an arrest is called reasonable force
  • Reasonable force is the amount of force needed to
    overcome the resistance by the person being
    arrested
  • Example- Using fists Using Fists
  • As the offender escalates an officer may escalate
    his use of force
  • Kicking or hitting the offender after he/she is
    handcuffed would be unreasonable use of force

28
Deadly Force
  • Use of deadly force has long been a controversial
    topic
  • It is permitted when absolutely needed
  • Jeopardy, ability and opportunity must be present
  • Police can protect their life or the life of
    another

29
Stopping of Vehicles
  • In 1979 in Delaware vs Prouse the Supreme Ct
    ruled that it was no longer constitutional to
    make routine stops or random spot checks
  • Today the court still rules that
  • Officers may stop a car on reasonable suspicion
  • If a traffic violation has occurred
  • Using point checks or road blocks as long as
    every citizen is subject to the stop
  • Officers can also legally order persons out of a
    vehicle for their safety (Mimms vs Penn 1971)

30
Search Warrants
  • Generally officers should obtain a search warrant
    prior to any search an seizure
  • A warrant is a court order issued by a judge
    based on probable cause describing the person,
    place, or auto to be searched
  • Officers generally execute warrants during
    daylight hours but there are exceptions
  • No knock provisions
  • Generally search warrants are not procured
    before the search because of no time to act

31
Exceptions to Search Warrants
  • Search warrant exceptions are called exigent
    circumstances
  • This means evidence will likely be destroyed if
    officers dont act
  • The suspects might get away
  • The officer might be injured
  • Incident to lawful arrest an officer has the
    right to search the suspects immediate
    surroundings to avoid potential injury

32
Field Interrogations
  • In 1968 Terry vs Ohio established the standard
    that allowed a policeman to conduct a stop and
    frisk
  • A stop and frisk is the temporary detainment of a
    person by a law enforcement officer for the
    purpose of an investigation, accompanied by a
    superficial examination by the officer of the
    persons body surface or clothing to discover
    weapons, contraband, or other objects related to
    criminal activity

33
Hot Pursuit
  • Another circumstance in which a warrant is not
    needed
  • In hot pursuit or close pursuit if officers chase
    a suspect into a building, they do not have to
    stop and get a warrant.
  • It would be self-defeating to have to do this

34
Consent Searches
  • Police can search without a warrant if consent is
    given by a person who has authority to give
    consent
  • The request cannot be in the form of a command or
    a threat
  • It must be a genuine request for permission
  • An oral reply must be received but a head nod is
    not enough
  • The search is limited to the area where consent
    is given

35
Consent Search Cases
  • 1974 Matlock vs U.S- Ruled a person sharing a
    room with another could give permission
  • 1990 Rodriguez vs Illinois- Police entered a
    Chicago apartment after victim (girlfriend) told
    police boyfriend had assaulted her and the police
    found cocaine

36
Plain View
  • Plain view evidence is unconcealed evidence
    inadvertently seen by an officer engaged in a
    lawful activity
  • Seizure of the evidence without a warrant is
    totally legal

37
Abandoned Property
  • Searches of a persons discarded garbage is not a
    4th amendment violation(Abel vs U.S. 1960
  • Trash left at the curb is ok too (Calf vs
    Greenwood 1988)

38
Inventory Searches
  • If a vehicle is impounded, officers have the
    right to enter and search the vehicle without a
    warrant for the purpose of noting all contents
  • In Colorado vs Bertine (1968) he was arrested
    while driving intoxicated and upon an inventory
    search canisters of drugs were found case was
    upheld

39
Open Fields Searches
  • In Hester vs U.S. (1924) the supreme court
    established an open fields exception
  • In this case the court said that field not
    immediately surrounding the house did not have
    the protection of the 4th amendment
  • In 1989 in Florida vs Riley agents flew over his
    house with a helicopter at 400 feet and
    discovered marijuana growing in Rileys
    greenhouse which was legal

40
Automobile Exceptions
  • Many students dont like getting stopped by the
    police and consider it harassment
  • We have 4th amendment protection but not as much
    as if you were in your home
  • Vehicles are considered very mobile objects and
    the supreme court is lenient on vehicle
    warrantless searches

41
Good Faith Exception
  • If police conduct a search in good faith and it
    is later discovered that the warrant is fault or
    found to be unsupported by probable cause, the
    good faith exception then applies
  • The is where the police act in reasonable
    reliance and good faith on a search warrant
  • In 1995 Evans vs Arizona he was arrested for a
    traffic violation in which a computer erred
    showed him with an outstanding warrant that
    should have been removed. Police found contraband
    and the supreme ct said ok

42
The Police and Custodial Interrogations
  • When there is not enough physical evidence police
    often resort to gain a confession from a
    defendant particularly in murder cases
  • Historically there have been abuses such as
    tortures beatings by the police
  • This came to be the 3rd degree

43
Path to Miranda
  • From 1936 to 1966 the Supreme Ct attempted to
    make police stop misconduct and comply with the
    5th amendment
  • 1936 Brown vs Mississippi
  • 1957 The McNabb-Mallory Rule
  • 1964 Escobedo vs Illinois
  • 1966 Miranda vs Arizona

44
The Police and Identification Procedures
  • Lineups, showups, and photo arrays are important
    in establishing the investigation of a suspect
  • Lineup- Is placing the suspect with a group of
    other people of similar characteristics (hair
    color, race, age, height, weight)
  • Showup- Involves bringing a suspect back to the
    crime scene
  • Photo Array- Is showing a photo of the suspect
    with other similar photos to a victim or witness

45
Other Identification Procedures
  • In Schmerber vs Calif 1966- Blood was forcibly
    taken from the suspect who was drunk driving
    this was not a violation
  • In Winston v Lee (1985) The supreme ct ruled that
    it was ok to make minor intrusions into the body
    but here they removed a bullet from Lee for
    evidence and police overstepped their right to
    secure the evidence in this manner

46
Summary
The police must know the law and conform to it.
To allow the injustices of the past would serve
to erode our justice system whereas we would no
longer be a free society
