Lecture 4 - Patrol Work Flashcards
Patrol Strategies
- Foot Patrol
- Motorized Patrol (vehicles)
- Biking Patrol (can access places cars cannot)
- Air Patrol (helicopter; aerial view)
- Marine Patrol (boats)
- Mountain Patrol (Horses)
- ATV Patrol (beaches)
Theoretical Frameworks: Routine Activities Theory
(TEST Q)
When 3 Elements Converge in space and time the crime is more likely to occur:
- Motivated Offender - Person who is willing to commit a crime
- Suitable Target - Anything or any person that crime can be committed against
- Absence of Capable Guardian - No Person or nothing that can prevent a crime from occurring (security guard, house alarm, etc.)
How Does This Theory Apply To Policing?
- Police Officers act as Capable Guardians, and therefore eliminate 1 of 3 elements
Theoretical Frameworks: Deterrence Theory (TEST Q)
People are rational minded and do not commit crime because cost of crime outweighs the benefit
- If we speed, we’ll get caught and punished (ticket outweighs benefit of getting to destination faster)
Theory relates to policing as police officers are the ones that deter people from committing crime
Patrol Strategies
Do Police Prevent Crime? NO
* Would mean police stopped crime occuring everytime and everywhere
Do Police Displace Crime? YES
* Means stopping it temporarily or moving the time and location of crime
2 Ways to Displace Crime?
Spatial Displacement: Move it elsewhere
Temporal Displacement: Move it around the clock
Kansas City Preventive Patrol Experiment (1972)
Kansas City PD conducted an experiment to analyze the effectiveness of routine preventive patrol
Divided City Into 3 Groups:
- Reactive Group - No routine preventive patrol - officers only respond to calls of service
- Proactive Group - 2-3x more preventive patrol than regular
- Control Group - Regular amount of patrol
Results: Did not significantly impact crime levels.
* Shows routine preventive patrol may not be valuable means to impact crime
Flaws:
* Implementation
* Volume
Spacial Unit Concern:
- Even if there was different levels of policing, public would not see changes because city is so big
4 Forms of Data & What They Aim To Measure
Survey Data - Collected through surveys or interviews
Aim: To measure public opinions on crime, attitudes towards police
Crime Data - Collected by police, represents reported criminal accidents
Aim: Measures frequency, type, location of reported crime
Arrest Data - Records of individuals that were arrested
Aim: To see who is being arrested, what offences, demographic of arrestees
Observation Data - Collected through direct observation of individuals or groups in natural settings
Aim: Measures Behaviour, Interactions, Situational Factors that cannot be captured through other data sources
Minneapolis Hot Spots Policing Experiment (Focused Patrol) (NEED TO KNOW AUTHOR (GROFF et. al) & NAME OF STUDY)
Identified 110 hotspots of crime and divided them by two.
* Intensified but intermittent patrol (3 hours per day at hotspots
Results:
* 2x Observed Patrol Presense
* Total crimes reduced by 6-13%
* Observed disorder reduced by 50%
Suggests that increases in police presence can reduce crime and disorder in high crime locations (hotspots).
Problems:
* Fidelity (Officer Boredom)
* Displacement
* Study did not account for police actions at locations (officers engaged with business owners vs. officers sleeping in car) (Groff et. al, 2015)
Philadelphia Policing Tactics Experiment (NEED TO KNOW AUTHOR (Lawrence W. Sherman) & NAME OF STUDY)
Randomized controlled field experiment to test 3 policing tactics. (Groff et. al).
- Foot Patrol (Increase Visibility and Access)
- Problem-Oriented Policing (Identifying and Solving Problems)
S.A.R.A Model (TEST Q):
S - Scanning (What is the problem)
A - Analyzing (What is Contributing)
R - Response (How can we improve problem)
A - Assessment (Did Response Work)
Ex. Kids Loitering Outside 7/11
- Offender-Focused Policing
- Increasing certainty of arrest for a small group of highly active offenders (police can deter others by doing this)
Results:
* Foot Patrol and Problem-Oriented Policing sites experienced no reductions in violent crime
* Offender-Focused Policing experienced 42% reduction in all violent crime
