1a. Basic Features

  • Local Control
  • Highly Fragmented
  • Variety

1b. Scope of Police

  • Approximately 18,000 police agencies
  • Primarily local (about 70-75%)
  • Most are small (typically < 10 officers)
  • Top 1% of agencies employ about 40% of officers
  • Police are the largest component of the Criminal Justice System in terms of expenses and employees
    • Expenditure example: about $129B in 2020
    • Approximately 80-95% of that amount goes to salary/benefits

1c. Police–Population Ratio (overview)

  • Municipal Police: 2.41000\frac{2.4}{1000} (officers per resident)
  • State and Local Public Safety Officers per 1,000 residents: iglrace 6.5,\, 5.7,\, 4.9,\, 4.2,\, 3.4,\, 2.6,\, 1.9 igrrace
  • Notes:
    • Staffing level does not straightforwardly imply deterrence; the relationship between staffing and crime rate is unclear
    • More police does not necessarily mean less crime
    • City vs county/metro comparisons illustrate variability in coverage and crime dynamics

Police–Population Ratio (illustrative examples)

  • City-level patterns suggest that staffing levels per 1,000 residents vary widely across U.S. jurisdictions.
  • Illustrative per-1,000 figures and officer counts:
    • Detroit: extofficersper1,000=3.7extwith2,067extofficersext{officers per 1,000} = 3.7 ext{ with } 2{,}067 ext{ officers}
    • San Diego: extofficersper1,000=1.3extwith429extofficersext{officers per 1,000} = 1.3 ext{ with } 429 ext{ officers}
    • Flint: extofficersper1,000=1.0extwith1,230extofficersext{officers per 1,000} = 1.0 ext{ with } 1{,}230 ext{ officers}
    • Virginia Beach: extofficersper1,000=1.6extwith88extofficersext{officers per 1,000} = 1.6 ext{ with } 88 ext{ officers} (note: 88 appears to be a data artifact; context suggests a larger force in reality)
    • Rockford: extofficersper1,000=2.0extwith1,430extofficersext{officers per 1,000} = 2.0 ext{ with } 1{,}430 ext{ officers}
  • Summary: high variation in ratios across cities; there is no simple one-size-fits-all staffing rule

2. Types of Police Agencies (Overview)

  • 2a. Local/Municipal – Broad role; comprise a majority of U.S. agencies (~12,000)
    • Big City Agencies (Top 15) – Primary focus on Order Maintenance (OM) and Law Enforcement (LE)
    • Crime is concentrated in big cities, which cover about 9% of the population but account for about 21% of violent crime; hence, they shape the dominant view of policing
  • 2a. Continued (Small Municipal & County)
    • Smaller city departments are more “average” in size and tend to perform OM more than LE
    • County Police Departments – 3 of the Top largest 15 agencies (about 20%)
    • Examples: Miami-Dade, Nassau County, Suffolk County
    • 6 of the Top 25 (about 24%) include: Baltimore County, Charlotte-Mecklenburg, Honolulu Police Department

2a. Type Continued (Sheriff)

  • Approximately 3,081 Sheriffs in the US
  • In 37 states, constitutional provisions define Sheriff responsibilities; all states except Alaska, Connecticut, and Hawaii (and Rhode Island excludes elected sheriffs)
  • Sheriffs are elected in all but Rhode Island
  • Roles can span multiple Criminal Justice System (CJS) functions:
    • Full Service (All 3): Law Enforcement (LE) + Court/Judicial + Corrections
    • Law Enforcement (LE) only
    • Civil-Judicial (Courts only)
    • Correctional-Judicial (all but LE)

2b. State Agencies

  • State Police are organized into three categories:
    • State Police: Traffic Regulation and Criminal Investigation
    • Highway Patrol: Traffic Regulation
    • State Investigation: Investigation
  • All 50 states have at least one state agency; some states have more than one
  • Examples of multi-agency structures:
    • California: Highway Patrol & Bureau of Investigations
    • Arkansas: Highway Patrol & State Police
    • Texas: Rangers, Criminal Investigation Division (CID), and Attorney General’s LE Division
  • Jurisdiction can be primary or secondary
  • State agencies provide services to local police, such as:
    • Lab services
    • Training facilities (academies)
    • Investigation assistance

2c. Federal Agencies

  • Employ about 133,000 sworn personnel
  • Narrow role: about 65% of federal law enforcement work is investigative
  • Creation and structure:
    • Homeland Security Act (2002) established the DHS
    • Jurisdiction overlaps with DOJ, Judicial Branch, and Independent agencies
  • Some federal agencies are obscure, e.g.:
    • FDIC Investigators
    • Bureau of Reclamation
    • Postal Inspectors
    • Odometer Fraud Investigators

3. Minimum Standards for Police Organizations

  • Federal level: Supreme Court decisions guide constitutional policing and procedure
  • State level: Basic training requirements (examples: ILETSB, MCOLES)
  • CALEA Accreditation: Voluntary but widely recognized

13. Fragmentation (discussion prompt)

  • Question posed: What problems arise from having many different police departments in a small area?
  • Implications include coordination challenges, duplicate efforts, inconsistent standards, resource competition, and uneven service quality

3b. Alternatives to Fragmentation

  • 1) Consolidation – Two towns merge; police merged with fire services into Public Safety; often uncommon and context-specific
  • 2) Contracting – Small towns pay a neighbor to provide police service; more common and less drastic than full consolidation

3c. Private Security

  • Private security workforce: approximately 900,000 people in the US
  • Industry size: about $50B
  • Issues with security services:
    • Equity concerns: more affordable for affluent communities
    • Lack of personnel standards and organizational consistency
    • Difficult collaboration between public and private security sectors
  • Real-world example: Philadelphia BID (Business Improvement District) collaborations

Key Takeaways

  • The U.S. police system is highly fragmented with thousands of local agencies and multiple layers (local/municipal, county, state, and federal).
  • Fragmentation drives diversity in missions (OM vs LE), workforce, training, and resources, but also creates coordination and standardization challenges.
  • There are formal and informal pathways to address fragmentation (consolidation, contracting, and private security partnerships), each with trade-offs.
  • Minimum standards exist at federal, state, and accreditation levels, but participation in accreditation is voluntary.
  • Population-to-officer ratios vary widely across jurisdictions, and higher staffing does not guarantee lower crime.
