Policing Roles, Operational Styles, and Departmental Functions

Foundations and Roles of American Policing

Position of Police in the Criminal Justice System:
- The police stand at the forefront of the criminal justice process.
- For the vast majority of citizens, personal contact with a local police officer represents their only direct experience with the criminal justice system.
- Most members of the public have never entered a courthouse for a criminal proceeding, nor have they been detained in a jail or incarcerated in a prison for any reason.
Societal Role Definitions and Conflict:
- Role: The rights and responsibilities associated with a particular position in society.
- Role Expectation: The specific behaviors and actions that members of society expect from an individual occupying a particular role. Expectations of police behavior depend heavily on how different individuals and groups perceive the police's societal function.
- Role Conflict: The psychological stress and frustration that results from attempting to perform two or more incompatible responsibilities simultaneously. This typically arises when the public's expectations of police duties diverge sharply from the official, administrative role assigned to law enforcement officers.
Prevailing Perspectives on the Police Role:
- Although public perceptions vary, the majority of viewpoints share common assumptions about law enforcement officers:
  - Officers act as community leaders dedicated to public safety.
  - Officers possess broad discretionary authority in their daily operations.
  - Officers resolve short-term sociological and technological problems for community members.
  - Officers are required to perform their duties in environments that can be hostile or dangerous.

Characteristics of Police Work and Occupational Danger

Core Characteristics of Police Work:
- Quick Decision Making: Officers are routinely placed in high-stakes circumstances requiring immediate choices without the benefit of prolonged deliberation.
- Working Independently: Officers carry out their responsibilities with substantial autonomy and minimal direct on-scene supervision.
- "Dirty Work": Officers regularly handle situations involving distress, physical trauma, unpleasant human environments, and social degradation that the general public avoids.
- Danger: Officers face potential injury or death from unpredictable, hazardous, and combative encounters.
Law Enforcement Officers Assaulted in the United States (Table 6.1):
- Total recorded officer assaults across all circumstances: $50,212$ ( $100\%$ ).
- Disturbance Calls: $16,256$ assaults ( $32.4\%$ ) — includes family quarrels, calls involving an individual with a firearm, and related domestic disturbances.
- Attempting Other Arrest: $7,820$ assaults ( $15.6\%$ ).
- Handling, Transporting, or Custody of Prisoners: $6,143$ assaults ( $12.2\%$ ).
- Investigating Suspicious Persons and Circumstances: $4,647$ assaults ( $9.3\%$ ).
- Traffic Pursuits and Stops: $3,972$ assaults ( $7.9\%$ ).
- Handling Persons with Mental Illness: $1,710$ assaults ( $3.4\%$ ).
- Burglary in Progress or Pursuing Burglary Suspects: $840$ assaults ( $1.7\%$ ).
- Civil Disorder: $677$ assaults ( $1.3\%$ ) — includes mass civil disobedience, riots, and related group disturbances.
- Robbery in Progress or Pursuing Robbery Suspects: $398$ assaults ( $0.8\%$ ).
- Ambush Situations: $240$ assaults ( $0.5\%$ ).
- All Other Circumstances: $7,509$ assaults ( $15.0\%$ ).

Operational Styles of Policing

Development of Operational Styles:
- Following formal recruit training and the acquisition of field experience, officers develop distinct operational styles.
- The emergence of distinct personal styles indicates that a police department has not succeeded in systematically training and deploying its personnel under a single, uniform philosophy and practical approach.
- Empirical research demonstrates that police departments do not possess a monolithic culture; officers serving within the exact same agency frequently exhibit significantly different attitudes and orientations toward their professional duties.
James Q. Wilson's Typology of Policing Styles:
- Legalistic Style:
  - Prioritizes strict adherence to violations of the letter of the law.
  - Relies heavily on threats of formal action or actual arrests to resolve disputes and handle infractions.
- Watchman Style:
  - Prioritizes public order and maintenance of community peace.
  - Emphasizes informal means of resolving disputes and addressing local problems rather than invoking formal legal sanctions.
- Service Style:
  - Prioritizes assisting citizens and serving the community over strict enforcement of criminal statutes.
  - Focuses on problem resolution, public support, and informal collaboration.

Core Police Functions: Patrol Operations and Strategies

Foundations of Patrol:
- Patrol is universally designated by police administrators as the "backbone" of the department.
- Patrol functions consume the largest amount of departmental time and require the greatest proportion of resources.
- Standard patrol duties encompass:
  - Responding to burglar alarms
  - Investigating traffic accidents
  - Administering care to injured persons
  - Intervening in and resolving domestic disputes
  - Answering dispatched radio calls for service
Preventive (Random) Patrol:
- Officers patrol city streets with minimal structured direction.
- Characterized as being "systematically unsystematic" and observant during the intervals between dispatched radio calls.
- Designed to prevent crime through a visible police presence while simultaneously ferreting out active offenses.
Directed Patrol and Crime Mapping:
- Patrol officers operate under specific departmental guidance or strategic orders detailing how to allocate their uncommitted patrol time.
- Empirical evidence confirms that directed patrol effectively decreases the incidence of targeted crimes, such as robberies and thefts from automobiles.
- Geographic Information System (GIS) Crime Mapping:
  - A technical tool used to enhance directed patrol strategies.
  - Charts and analyzes geographic crime patterns within defined boundaries.
  - Generates multi-layered visual maps displaying numerous distinct fields of data, enabling close tracking of active criminals and crime hot spots.
Aggressive Patrol and Field Interrogations:
- Aggressive Patrol: The systematic practice wherein an entire patrol division executes a high volume of traffic stops and field interrogations.
- Field Interrogation: The temporary detention and questioning of pedestrians or motorists observed under suspicious circumstances.
- Drawbacks of aggressive patrol:
  - Causes significant inconvenience and irritation to innocent citizens subjected to random stops.
  - Presents managerial challenges in maintaining uniform officer motivation to execute assertive, proactive enforcement tactics.
Foot Patrol:
- The practice of assigning officers to patrol specific neighborhood beats on foot.
- Research indicates that foot patrol has not been proven to provide a statistically significant deterrent effect on crime rates.
- Foot patrol does, however, generate significant improvements in working relationships and trust between citizens and police officers.

Criminal Investigation: Functions, Roles, and Technological Advances

Definition and Scope of Criminal Investigation:
- A lawful search for people and physical things designed to reconstruct the factual circumstances surrounding an illegal act.
- Determining the identity of and apprehending the guilty party.
- Assisting the state's official prosecution of the accused offender.
- While detectives receive the greatest degree of media attention and public glorification, they represent only one functional operational unit within a police department.
- Investigators handle diverse assignments, including hit-and-run accidents, undercover operations, and comprehensive background investigations on department applicants.
Two-Part Investigative Structure:
- Preliminary Investigation: Conducted primarily by uniformed patrol officers who first arrive at the scene (except in homicide investigations or other unusually complex crimes where detectives assume immediate control).
- Follow-Up Investigation: Carried out by plainclothes detectives once the initial scene has been stabilized and processed.
Core Investigative Duties:
- Locating witnesses and identifying suspects.
- Apprehending and arresting criminal offenders.
- Collecting, preserving, and analyzing physical evidence.
- Interviewing witnesses and victims.
- Interrogating criminal suspects.
- Writing detailed official case reports.
- Recovering stolen property.
- Seizing illegal contraband.
- Preparing cases for prosecution and providing sworn testimony in court proceedings.
Working Conditions and Roles of Detectives:
- Advantages over Patrol Officers:
  - Exemption from wearing standard police uniforms.
  - Capacity to operate with personal anonymity during duty hours.
  - Steady work hours, typically concentrated during daytime shifts with weekend days off.
  - Dedicated office space and personal desks.
  - Elevated occupational prestige and community standing.
  - Higher compensation levels and higher formal rank within many agencies.
  - Substantially greater day-to-day freedom in scheduling and task execution.
- Productivity Obstacles and Pressures:
  - Crimes are frequently difficult or impossible to solve with the evidence available.
  - Witnesses who possess vital information are often unwilling to cooperate or become involved with law enforcement.
  - Overall statistical clearance rates and chances of successfully solving crimes remain low, creating ongoing professional stress.
Technological Identification Advances in Investigation:
- Integrated Automated Fingerprint Identification System (IAFIS):
  - An expensive computerized database that provides investigators with the capability to search through and compare thousands of fingerprint records to locate matching sets rapidly.
- DNA Profiling:
  - Analyzes blood, semen, hair, or other biological substances to establish an individual's unique genetic profile.
  - Serves three vital investigative functions: linking suspects to specific crime scenes or eliminating them from suspicion; identifying "cold hits" by comparing unknown biological evidence from crime scenes against national databases; and exonerating wrongfully convicted individuals serving prison sentences for murder and rape.

Specialized Police Functions: Cybercrime and Traffic Operations

Cybercrime Operations:
- Defined as the deployment and use of computer technology to perpetrate criminal offenses.
- Represents a rapidly escalating concern for modern law enforcement agencies, with annual financial losses totaling approximately $\$10\text{ billion}$ .
Traffic Enforcement and Accident Investigation:
- Motor vehicle accidents on American highways and streets result in more than twice as many deaths annually as criminal homicides.
- A significant percentage of fatal vehicular crashes involve alcohol impairment.
- Special Traffic Accident Investigation Crews: Dedicated units deployed in specialized agencies to perform focused traffic safety duties:
  - Educating motorists on highway safety principles.
  - Enforcing motor vehicle laws, targeting violations directly linked to accident causation.
  - Recommending structural and engineering changes to roadways to mitigate traffic hazards.

Drug Enforcement and the War on Drugs

Local Drug Enforcement Strategies:
- While national drug interdiction is prioritized by federal and state agencies, the operational burden of the "War on Drugs" is predominantly borne by local municipal police departments.
- Agencies implement eight primary enforcement strategies:
  - Street-Level Enforcement: Visible tactics such as buy-bust operations, dealer arrests, and aggressive patrol in drug markets.
  - Mid-Level Investigations: Targeting wholesalers and local distributors using undercover operations, informants, and surveillance.
  - Major Investigations: Prolonged, complex operations directed at dismantling drug trafficking organizations and leadership cartels.
  - Crop Eradication: Destroying illicit drug crops (such as domestically grown cannabis) at the point of cultivation.
  - Smuggling Interdiction: Intercepting narcotics along domestic supply lines, transit routes, and entry points.
  - Problem-Oriented and Community Policing Strategies: Engaging residents and local merchants to eliminate open-air markets and secure drug-prone properties.
  - Drug Demand Reduction: Department-sponsored educational initiatives to discourage potential users.
  - Asset Forfeiture: Seizing funds, real estate, and personal property purchased with drug profits or utilized to facilitate trafficking.
Extent of Illicit Drug Use in the United States (Persons Aged 12 or Older, 2015 - Table 6.3):
- Marijuana:
  - Lifetime: $117,865\text{k}$ individuals ( $44.0\%$ )

  - Past Year (2015): $24,539\text{k}$ individuals ( $9.2\%$ )
  - Month Before Survey: $9,273\text{k}$ individuals ( $3.5\%$ )
Criticisms of the War on Drugs:
- None of the standard law enforcement enforcement models have produced meaningful, long-term reductions in drug availability or consumption.
- Government policies exaggerate the inherent dangers of illicit drug use.
- Drug law enforcement disproportionately impacts racial minorities, rendering the campaign racially biased in execution.
- The immense profits of the illicit drug trade have led to widespread corruption among police personnel.
- Enforcement operations require immense financial expenditures, draining scarce public resources away from more pressing societal needs.

Community Policing Philosophy, Components, and Problem Solving

Shift Away from the Professional Model:
- For several decades, policing adhered strictly to the professional model, which was anchored by three core strategies:
  - Routine preventive patrol
  - Rapid response time to emergency calls
  - Follow-up investigations conducted by detectives
- Broken Windows Theory:
  - Formulated by James Q. Wilson and George Kelling.
  - States that if visible physical and social disorder (signs of crime) are left unaddressed in a neighborhood, more serious, violent, and costly criminal activity will inevitably follow.
  - Concludes that to resolve community crime patterns and diminish citizen fear, police officers must maintain continuous, close personal contact with residents.
Philosophical Foundations of Community Policing:
- Community policing redefines safety as a shared responsibility divided equally between citizens and law enforcement.
- Officers and residents act in close collaboration across a four-stage joint process:
  - Identifying community problems
  - Proposing practical solutions
  - Implementing planned actions
  - Evaluating the tangible results within the community
Community Partnerships:
- The foundational element of community policing is establishing and preserving mutual trust between the public and police officers.
- Operational strategies to build partnerships:
  - Conducting direct dialogues with local business proprietors.
  - Visiting residents directly in their homes.
  - Supporting and collaborating with local neighborhood watch organizations.
  - Maintaining regular, two-way communication channels with residents.
The SARA Problem-Solving Model:
- Effective problem solving requires officers to devote time to uncovering real neighborhood concerns and officially acknowledging their legitimacy.
- Scanning (S): Identifying specific, recurrent problems within the community.
- Analysis (A): Conducting in-depth inquiry into the underlying causes, conditions, and dynamics driving the identified problems.
- Response (R): Formulating, selecting, and executing targeted, customized intervention solutions.
- Assessment (A): Evaluating the post-intervention data to determine the actual effectiveness and impact of the implemented solution.
Change Management for Implementation:
- Adopting community policing requires substantial internal structural transformations:
  - Transitioning from rigid paramilitary hierarchies toward flexible management systems.
  - Re-evaluating and placing central institutional value on the role of the patrol officer.
  - Decentralizing authority by shifting decision-making discretion and operational responsibility downward through the rank structure.
- Full operational success requires a shared philosophical understanding and authentic commitment from both police agency personnel and community members.

Terrorism and Homeland Security

Historical Development and Core Elements:
- Terrorism is one of the oldest manifestations of human conflict, utilized by individuals and factions before organized societies initiated formal warfare.
- The Federal Bureau of Investigation (FBI) dates the modern era of terrorism to the late 1960s.
- Domestic U.S. soil remained largely insulated from significant international terrorist attacks until the February 1993 World Trade Center bombing.
- Universal Core Elements of Terrorism:
  - Fear
  - Panic
  - Violence
  - Disruption
- FBI Definition of Terrorism: "The systematic use of terror or unpredictable violence against governments, publics, or individuals to attain a political objective."
Domestic Terrorism:
- Defined as the unlawful use, or threatened use, of force or violence committed by a group or individual based and operating entirely within the United States or its territories without foreign direction.
- Carried out against persons or property to intimidate or coerce a government, the civilian population, or any segment thereof, in furtherance of political or social objectives.
- Four Subcategories of Domestic Terrorism:
  - Right-Wing Terrorist Groups: Factions characterized by hostility toward government authority in general and resistance to federal and state government regulations in particular.
  - Left-Wing Terrorist Groups: Factions adhering to revolutionary socialist ideology, aiming to establish radical systemic changes entirely outside the legal political process.
  - Special Interest Terrorist Groups: Radical fringe components of broader social causes, including antinuclear, environmental, pro-life, and animal rights movements.
  - Individual or "Lone Wolf" Terrorists: Independent actors operating alone or in small, isolated cells, deliberately avoiding organizational ties to evade detection by intelligence and law enforcement agencies.
International Terrorism:
- Defined as violent acts dangerous to human life that constitute criminal violations under United States federal or state statutes (or that would constitute crimes if committed within U.S. jurisdiction).
- Intended to intimidate or coerce a civilian population, influence state policies through intimidation or coercion, or affect the conduct of a government via assassination or kidnapping.
- Three Categories of International Terrorists:
  - State Sponsors of Terrorism: Sovereign nations that systematically utilize terrorism as a deliberate instrument of foreign policy.
  - Formal Terrorist Organizations: Autonomous, transnational organizations maintaining independent command hierarchies, trained personnel, operational infrastructures, financial funding streams, and dedicated training centers.
  - Loosely Affiliated Extremists and Rogue International Terrorists: Unaffiliated individuals or fluid networks driven by radical ideologies without structured transnational oversight.
United States Counterterrorism Policy Principles (Bush Administration):
- No Concessions: Make no concessions to terrorists and strike no deals under any circumstances, including scenarios where U.S. citizens are held hostage.
- Relentless Justice: Bring all terrorists to justice for their criminal acts, regardless of the operational duration required.
- State Isolation: Isolate and apply severe economic, diplomatic, and political pressure against state sponsors of terrorism to compel changes in state conduct.
- Allied Capability Enhancement: Actively bolster the counterterrorism infrastructure and defensive capabilities of foreign nations that cooperate with the United States and request assistance.
