criminal justice unit 5 study guides

Core Concepts and Theories

• Policing involves maintaining public order, enforcing laws, and preventing and detecting crime
• Sir Robert Peel established the London Metropolitan Police in 1829 based on principles of crime prevention, public approval, and minimal use of force
• Broken Windows Theory suggests that visible signs of disorder (broken windows) lead to more serious crimes if left unaddressed
  • Addressing minor offenses (vandalism) can prevent escalation to major crimes (robbery)
• Problem-Oriented Policing (POP) focuses on identifying and analyzing specific crime problems to develop targeted solutions
  • Involves scanning, analysis, response, and assessment (SARA model)
• Procedural Justice Theory emphasizes the importance of fair and respectful treatment by police to enhance legitimacy and public cooperation
• Situational Crime Prevention aims to reduce opportunities for crime by altering the environment (improved lighting, security cameras)
• Intelligence-Led Policing (ILP) uses data analysis and intelligence gathering to inform decision-making and resource allocation

Historical Development of Policing

• Early policing in the United States was influenced by the British model, with watchmen and constables responsible for maintaining order
• The first modern police department was established in Boston in 1838, followed by New York City in 1845 and other major cities
• In the early 20th century, policing focused on professionalization, with the introduction of formal training, specialized units, and scientific methods
  • August Vollmer, chief of the Berkeley Police Department, advocated for college-educated officers and the use of forensic science
• The 1960s saw a shift towards community policing, with an emphasis on building relationships between police and the communities they serve
• The 1970s and 1980s witnessed the rise of problem-oriented policing and the use of data-driven approaches to crime reduction
• The 1990s and 2000s saw the increasing use of technology in policing, including the adoption of CompStat (computer statistics) for crime analysis and deployment

Types of Policing Strategies

• Traditional Policing relies on reactive responses to crimes and calls for service, with a focus on arrest and enforcement
• Community Policing emphasizes partnerships between police and the community to identify and solve problems collaboratively
  • Involves foot patrols, community meetings, and youth programs
• Problem-Oriented Policing (POP) focuses on identifying and analyzing specific crime problems to develop targeted solutions
• Hot Spots Policing concentrates resources on high-crime areas to deter and prevent criminal activity
• Predictive Policing uses data analysis and machine learning to anticipate and prevent crime
• Evidence-Based Policing applies research and evaluation to inform best practices and decision-making
• Zero-Tolerance Policing involves strict enforcement of all laws and regulations, regardless of the severity of the offense

Community Policing and Engagement

• Community policing aims to build trust and collaboration between police and the communities they serve
• Involves proactive engagement through foot patrols, community meetings, and problem-solving partnerships
• Encourages officers to develop a deep understanding of the unique needs and challenges of their assigned communities
• Emphasizes the importance of procedural justice, treating individuals with fairness, respect, and transparency
  • Procedural justice enhances police legitimacy and public cooperation
• Community engagement activities include youth programs (mentoring), neighborhood watch, and citizen police academies
• Requires a shift in organizational culture and training to prioritize community partnerships and problem-solving
• Challenges include resource constraints, resistance to change, and maintaining community trust in the face of high-profile incidents

Technology in Modern Policing

• CompStat (computer statistics) revolutionized policing by using data analysis to inform deployment and resource allocation
  • Allows for real-time crime mapping and identification of emerging trends
• Body-worn cameras provide transparency and accountability, recording interactions between police and the public
  • Can help resolve complaints and provide evidence in court proceedings
• Automated license plate readers (ALPRs) scan and record vehicle license plates, aiding in investigations and locating stolen vehicles
• Facial recognition technology assists in identifying suspects and persons of interest, but raises privacy concerns
• Predictive policing software uses historical crime data and machine learning to anticipate and prevent crime
  • Helps allocate resources to high-risk areas and times
• Drones and unmanned aerial vehicles (UAVs) provide aerial surveillance and support for search and rescue operations
• Social media monitoring allows police to gather intelligence, engage with the community, and disseminate information during emergencies

Challenges and Ethical Considerations

• Racial profiling and biased policing erode public trust and undermine the legitimacy of law enforcement
  • Requires ongoing training, monitoring, and accountability measures to address implicit bias
• Use of force, particularly against minority communities, has led to increased scrutiny and calls for reform
  • Emphasizes the need for de-escalation training and alternatives to lethal force
• Balancing crime control and community trust is a constant challenge, requiring open communication and transparency
• Privacy concerns arise with the use of surveillance technologies (facial recognition) and data collection
  • Requires clear policies and oversight to protect individual rights
• Militarization of police, with the use of military-grade equipment and tactics, can escalate tensions and undermine community relations
• Mental health and wellness of officers is a critical concern, given the high-stress nature of the job and exposure to trauma
  • Requires access to support services and a culture that prioritizes mental health
• Corruption and misconduct erode public trust and require robust internal affairs processes and external oversight

Case Studies and Real-World Applications

• The LAPD's Community Safety Partnership (CSP) program embeds officers in high-crime housing developments to build relationships and reduce violence
  • Resulted in significant reductions in crime and improved community trust
• The Milwaukee Police Department's Homicide Review Commission brings together police, community members, and service providers to analyze homicide cases and develop prevention strategies
• The Camden County Police Department (New Jersey) underwent a complete reorganization in 2013, emphasizing community policing and data-driven strategies
  • Achieved significant reductions in crime and improved community relations
• The Seattle Police Department's Crisis Intervention Team (CIT) provides specialized training for officers responding to individuals in mental health crisis
  • Emphasizes de-escalation and connecting individuals with appropriate services
• The Rialto Police Department (California) implemented a body-worn camera program, resulting in significant reductions in use of force incidents and citizen complaints
• The High Point Drug Market Intervention (North Carolina) used a problem-oriented approach to close open-air drug markets and connect offenders with social services
  • Achieved significant reductions in crime and improved community quality of life

Future Trends and Innovations

• Continued integration of technology, including artificial intelligence and machine learning, to support data-driven policing strategies
• Expansion of community policing and engagement efforts, with a focus on building trust and legitimacy
  • Increased use of social media and digital platforms for community outreach
• Greater emphasis on evidence-based policing, using research and evaluation to inform best practices and decision-making
• Addressing the root causes of crime through partnerships with social service agencies, mental health providers, and community organizations
• Increased focus on officer wellness and resilience, with the development of peer support programs and access to mental health resources
• Reimagining public safety, with the exploration of alternative response models (mental health professionals) for certain types of calls
• Continued efforts to diversify police departments and build workforces that reflect the communities they serve
• Emphasis on procedural justice and implicit bias training to ensure fair and equitable treatment of all individuals
