Study Notes on Police Patrol

Purpose: Police patrol aims to maintain presence in the community to prevent crime.
Common Types: The most prevalent type of police patrol is vehicle patrol.

Reactive Policing: Involves responding to incidents after they have occurred rather than preventing them beforehand.

Geographic Jurisdictions: Police patrol areas are designated geographic jurisdictions known as beats.
Beat Size: The size of each beat is determined by factors such as the number and nature of calls received.
Police Patrol and Call Priority: Effective allocation of patrol units based on the urgency and type of calls received.

Prioritization of Calls: Critical calls are prioritized for a faster response.
Emergencies: Emergencies require more resources and quicker response times as they are of utmost importance.

The 311 System: A non-emergency number used for police and/or city services. It aims to reduce the volume of calls to 911, which are often still managed by police.

Definition: DPRs are response strategies that manage police workloads by allowing officers to focus on higher-priority incidents, optimizing the use of time and resources.
Characteristics: These responses may not always involve immediate dispatch and can limit proactive policing efforts.

Deterrent Effect: The presence of marked police vehicles in certain areas can deter criminal activity.
Engagement Variables: The effectiveness of preventive patrol is dependent on staffing and time available for patrol duties.

Assignment: Officers are strategically assigned to specific locations known as "hot spots" where crime rates are higher.
Critics' Concerns: This method is criticized for potentially leading to over-policing in certain areas that may be perceived as disproportionately targeted.
Target Categories:
- Hard Targets: Locations that are highly guarded.
- Soft Targets: Areas that are unprotected or vulnerable to crime.

Findings: The experiment's results indicated that variations in patrol levels did not significantly affect crime rates.
Public Perception: Although there was no effect on crime, public perception of safety increased in areas with more patrol.
Replication in Other Cities: Similar experiments in Newark, NJ, showed consistent results regarding public perceptions of safety.

Concept: Criminal activity is often concentrated in specific areas, necessitating targeted police efforts in these locations known as hot spots.
Characteristics of Hot Spots:
- These are areas with a high concentration of crime within small geographic spaces.
Additional Resources: Hot Spot Policing often involves deploying additional squad cars, enhancing focus on detecting and seizing illegal guns.
Results: Increased illegal gun seizures reported with potential deterrent effects noted in crime rates.

Effectiveness Recognition: Hot Spot Policing is widely accepted as an effective crime reduction strategy.
Community Relations: There are concerns that this approach may strain community relationships with law enforcement.

Overview: The strategy emphasized increased police presence and engagement with the community to deter minor offenses and prevent larger crimes.
Overpolicing Elements: The approach often led to increased scrutiny and resource allocation towards minor illegal conduct.

Definition: Police crackdowns involve concentrated efforts to deter crime through three major events: awareness, presence, and consistency in enforcement.
Temporary Deterrence: Intended to create an initial deterrent effect, leading to potential residual impacts on crime rates.
Relation to the War on Drugs: Crackdown strategies were notably utilized during the War on Drugs.

Commonality: Traffic stops are the most frequent reason for police contact, typically resulting from violations that can lead to further investigative actions.
Effectiveness Concerns: Limited evidence supports that these stops actively reduce crime; studies also indicate potential biases affecting their application and effectiveness.

Legal Basis: Conducted under reasonable suspicion, often involving frisking for weapons. Such stops account for about 1% of all citizen-police interactions, commonly referenced as Terry stops.
Case Law: Originating from the landmark case Terry v. Ohio, these stops and frisks are subjected to ongoing scrutiny with mixed research results regarding their impact on crime reduction.

Safety Benefits: Two-officer squads provide enhanced safety and support in high-risk situations, allowing for immediate backup that reduces risks during patrol in potentially dangerous areas.
Cost Efficiency: One-officer units may offer better cost efficiency, allowing police departments to allocate resources more effectively; however, they increase risks due to lack of immediate support during critical incidents.

Popularity: Foot patrol represents the second most common form of police patrol, particularly favored by larger police departments committed to community policing efforts.
Goals: Aimed at reducing crime and fear while improving personal relationships within the community.

Perceptions of Crime: Foot patrol has been shown to correlate with perceived lower crime levels.
Effectiveness: Crime reduction effects are particularly noted in hot spots, with increased perceptions of safety in the areas being actively patrolled.

Intelligence Use: Strategies depend heavily on gathering and utilizing criminal intelligence to identify repeat offenders.
Impact on Law-Abiding Citizens: These approaches are designed to be less intrusive to law-abiding citizens while being more precise in reducing crime overall.
