1 Police Patrol Management Question: How do you most effectively allocate police personnel? Answered with the tools of scientific management. PATROL - the backbone of policing Majority of officers assigned to Patrol provide the bulk of police services Patrol officers as “Gatekeepers” to CJS Patrol is the formative part of an officer’s career Assignments based upon seniority New officers start where? Patrol Street experience is shared among all officers: bonding Patrol considered least desirable assignment

2 Police Patrol FUNCTIONS OF PATROL Deter Crime
Enhance sense of public safety through police presence To make officers available for service delivery by physically distributing them throughout space

3 ORGANIZATION & DELIVERY OF PATROL
Police Patrol ORGANIZATION & DELIVERY OF PATROL Number of Officers: Police-Population Ratio Has little relationship to crime rate or calls for service Cities with high crime often have more officers Allocation & Distribution of Officers to Patrol Based on workload formulas Time of Day (more serious crime at night) Location (crime/disorder more common in poorer areas; lower income disproportionately racial minority) Questions: -No standard among police depts. -Geographic changes in neighborhoods

4 ORGANIZATION & DELIVERY OF PATROL
Assignment to Shifts & Areas Variety of Assignment Methods Seniority System Rotation Research (PERF) on frequent shifting shows effects include loss of sleep, health probs, on-the-job accidents, family probs, low morale Hot Spots: Areas that receive a disproportionate number of calls for service Sherman (1989) Minneapolis Study: 5% of addresses account for 64% of calls (60% no calls)

5 Hot Spots

6 Mapping and Patrol

7 TYPES OF PATROL Most (84%) police patrol is automobile
Cars provide more efficient patrol than foot Cover more area, pass each point more often Patrol in an unpredictable manner Respond quickly to calls for service Shift from foot to car occurs from s Consequences of patrol cars loss of direct contact with citizens (especially law-abiding) citizens may begin to see police as “occupying army”

8 Police Operations Foot Patrol
Police-community relations crises of 1960s restores use of foot patrols Also important in community policing models Costs: coverage area is much more limited expensive Benefits: gains in police-community relations

9 More on Patrol as the Modal method of Policing
Number of officers per patrol unit: How many officers do you commit to a unit? 1 or 2 Most involve single officer, though police rank and file have traditionally called for more 2 officer units. Why? Rank and file concerns about 1 officer units unfounded: Assaulted less often Made more arrests Wrote more crime reports

10 Styles of Patrol Individual Styles of officers are important
Amount of work accomplished (productivity: volume of arrests, response to calls for service) depends on officer work style Active Officer-initiated actions (stops, questioning, traffic, frisking) Re-active Citizen initiated work: Officers may be passive or active in their response to complaints

11 Styles of Patrol Supervisory Styles also important
How closely is patrol work scrutinized by shift supervisor? Expectations for appropriate police behavior & productivity impact patrol Research on Patrol Sergeants supports this idea Active role of Sergeants often is in terms of suggestion: protection of discretion as a fundamental part of police work Organizational Styles JQ Wilson: 3 Styles: Watchman: emphasizes peacekeeping; not aggressive in law enforcement; little control over officers Legalistic: aggressive crime-fighting; greater control over officers Service: responsiveness to community expectations; more common in low-crime communities

12 How effective is Patrol?
Aspects of evaluating the effectiveness of police patrol: Response Time is the gold standard for Police & Public Response time should increase likelihood of arrest Should increase satisfaction with police Research does not support Response Time Little direct impact on clearance rates Largely due to cold crime phenomena Discovery time by citizens Reporting time to police Both are largely beyond police control

13 Use of Time on Patrol How is patrol time utilized by cops? Largest breakdown is b/t committed vs. uncommitted time Lots of contradictory evidence about how much time is committed time Regardless, police presence is always provided by patrol, even if officers are “evading” duty.

14 How effective is Patrol?
Random Patrol Kansas City Preventive Patrol Experiment Landmark event in American policing 1st scientific experiment of patrol effectiveness Funded by 3rd party (Police Foundation) - objectivity Research Design 15 Beats divided into 3 groups Reactive Beats: no preventive patrol, officers only respond Proactive Beats: beats patrolled 2-3 times normal rate Control Beats: normal level of patrol Measured impact of different levels of patrol

15 Patrol Effectiveness Research Design
Measured impact of different levels of patrol Criminal Activity Reported Crime Arrest Victimization Survey Community Perceptions and Attitudes Officer Behavior and Dept Practices Findings & Implications No significant effect on: criminal activity citizen feelings of safety citizen attitudes toward the police crime rates citizen recognition of different levels of patrol

16 Patrol Effectiveness Explanations for non-findings?
Patrol spread too thin Crimes occurring indoors unaffected “Phantom” effect of patrol Levels of patrol were only thing tested, not officer activities Stimulated interest in application to tests of Foot Patrol (Newark Foot Patrol Experiment ) Similar design Findings: Little or no impact on measurable serious crime Significant improvement in community perceptions: less fear of crime More positive attitudes about police (vice-versa)

17 Patrol Effectiveness Effectiveness of Patrol can be improved
Crackdowns and Directed Patrol Hot Spots Patrol in KC (Sherman & Rogan –B/B) Focused on specific type of crime: Gun Crimes Crackdown upon illegal possession Did this type of patrol reduce specific crimes? Reduce all crimes? Was deterrent effect constrained to hot spot areas? Did adjacent areas experience increases in crime? (this “spillover” idea is known as displacement)

18 Crimes that define Contemporary Police Work
Drugs/Gangs Crack has been the defining influence on police work in the past 20 years – replaced by others? Business competition & no legitimate channels for grievance/accountability in illicit markets creates violence Decrease over the past decade Proactive Approach is somewhat unique relative to police responses to other kinds of crime Chambliss: Policing the Ghetto Underclass RDU tactics Rips Vehicle Stops Search Warrants Moral Panics & the Culture of Crime/Fear

19 Contemporary Police Work: Drug Enforcement Strategies
Supply Reduction Buy & Bust: undercover officers pose as buyers Trading Up: (Identify “kingpins” through lower level dealers as informants) Penetration of Drug Networks through long-term undercover work (Rips) Crackdown: intensive enforcement in specific areas (neighborhoods - RDUs) Effective? Generally no… Threat of arrest is not effective as a deterrent – why? Replacement effect in network Trading Up ineffective Demand Reduction Drug Education Programs (DARE) Largely ineffective Continue to operate proactively Generate positive publicity High profile “busts” create the appearance of effectiveness Goes to Police Legitimacy

20 Police Operations Police Investigations
1) Police are expected to help prevent crime (most frequently through patrol) Basic element of COP & POP Rejects traditional model that police are responsible for crime control 2) Apprehend Criminals Requirements: a. learning of a crime b. official recording c. attempt to ID and arrest

21 Police Operations Police Investigations
Factors influencing the reporting of crime: Learn through reactive response most common Citizen reporting highly discretionary (gatekeepers) Police rarely discover crimes in progress Victims report roughly 35% of the time Influences on reporting: seriousness, violence, injury, expense of loss Reasons for not reporting: crime unimportant, pessimistic about anything being done, crimes as private

22 Police Operations Police Investigations
Myths about Detective Work: The CSI complex: Exciting, Requires courage/skill, all crime is “solvable” Organization of Investigations: located in different unit, size varies tremendously Detective Position: high status, discretion, autonomy, no uniforms, defined measures of performance Status varies by unit (homicide highest)

23 Police Operations Police Investigations
Investigation is 2 Staged Process: 1) Preliminary Investigation (5 Steps) - ID and arrest of suspect - Aid to victims (medical) - Securing crime scene - Collecting physical evidence - Preparing preliminary report Patrol makes 80% of all arrests (suspect near the scene)

24 Police Operations Police Investigations 2) Follow up investigations
case is assigned to detectives for follow up - routine activities: interviews, crime scene - secondary activities: canvassing witnesses, discussing case with super., collecting evidence - tertiary activities: discussion of case with other officers, interviewing suspects, checking records, conducting stakeouts

25 Research on Police Investigations
Are some PDs better able to solve crimes? What explains differences in investigation outcomes across cases / investigators / departments? 2 Studies interested in those questions: Chaiken et al. (B/B) Brandl & Frank (B/B)

26 Police Operations Police Investigations
Arrest discretion: arrests occur in only about half of the situations where sufficient evidence exists to arrest (Black 1984) Officers influenced by situational factors: severity, evidence, victim behavior, victim/suspect relationship, suspect demeanor

27 What is an arrest? 4 Perspectives:
Legal: When a suspect is not free to leave Behavioral: may include command to stop; physical restraint (cuffs) Subjective: Citizen perception Official: arrest report filed, records vary in different departments and at different stages Consequence? Many people believe an arrest has occurred when no record of an arrest exists

28 Success/Failure in Crime solving
From a police standpoint, success is when an arrest is made Most important factor in successful arrest is knowledge of suspect identity Most common: violent crime; V/O relationship 21% of all reported Index Crimes are cleared Much of this is due to “structural” factors of the case. Evidence is mixed on whether police can have an impact on investigation success Technology is not as useful a tool as culture views it (3% of NYPD cases with usable fingerprints result in an arrest)

29 Improving Investigation & Special Techniques
Encourage more Cooperation: Between police and citizens Between patrol and detective units Special Investigation Strategies: Undercover work Problems: socializing officers to “lie”, going native, weakens ties to conventional others, lack of supervision Informants Especially useful in “victimless” crimes (drugs); basis of exchange creates appearances of conflicts of interest; integrity of police; quality of informant info
