Police Strategies – What Works?
Police Strategies – What Works?
Response time to 911 calls
Incident-driven policing
Response time as a benchmark of efficiency
Differential response
“Cold” calls versus “hot” calls
Location intelligence
General vs. Directed Patrol
General patrol:
relies on officers to monitor
a certain area to detecting
crimes in progress or
preventing crimes due to
their presence.
Also called preventive
patrol, or random patrol.
Directed patrol:
is designed to respond to a
specific criminal activity at a
specific time.
Targeted areas are labeled
hot spots.
Kansas City Experiment
The Kansas City Random Preventive Patrol
Experiment: Control beats – same car patrol
Proactive beats – more car patrol
Reactive beats – no car patrol
Interpreting the Kansas City Experiment: Questioning the effectiveness of random patrol –
Lawrence Sherman – hot spots – foot patrol
Reactive and Proactive Arrest
Reactive Arrests:
Arrests that come about
as part of the ordinary
routine of police patrol
and calls for service .
Proactive Arrests:
Arrests that occur when
police take the initiative
to target a particular
type of criminal
behavior.
Broken WindowsBroken Windows Theory (Wilson & Kelling):
Destroyed neighborhood = criminal activity is tolerated
Target quality-of-life crimes = reclaim neighborhood
Based on order maintenance of neighborhoods
Problem Oriented Policing
Examine long-term implications –examines all elements of a crime –focused on prevention – Herman Goldstein
Elements of Problem Oriented
Policing
Scan – examine circumstances of crime(s)
Analysis – break down causes of crime
Response – do something sensible
Assessment – measure results
1. Patrolman Smith, a white man, frequently hears his fellow officers (all white men) make degrading remarks about various minority groups and women while they are away from the public and in the station. When the other officers make these remarks Smith ignores them.
2. Patrolman Lawrence, eats at a donut shop each day with his partner, a more senior officer, despite the fact that he is overweight and doesn’t actually want to eat there.
3. Patrolman Wilson likes to brag about how he is extra rough with arrestees who give him a hard time. He enjoys handcuffing them really tightly and shoving them into his squad car. His fellow officers seem to think his stories are hilarious.
Police Subculture
The values and perceptions that are shared by members of a police department. These values permeate agencies and are taught to new officers through a process of socialization.
Accepting Police Subculture Attending a recruit academy
Working with a senior officer who passes on the lessons of police work and life
First felony arrest
Using force to make an arrest for the first time
Witnessing major traumatic incidents for the first time
Blue Curtain
The Blue Curtain, aka the “blue wall of silence”
Police cynicism
Physical and mental dangers associated with police work Guns and crashes
Chronic stress
Health issues
Use of Force
Force = authority
Goal of force – use only for a credible threat – level of force should match threat
Garner v. Tennessee (1985) –unconstitutional to use force w/out threat
don't tase me, bro
don't tase me - what happened
Plain View Doctrine
1. What are the three elements needed in order to make a seizure of contraband under the plain view doctrine?
2. Make a scenario that follows the plain view doctrine properly.
3. Make a scenario that does not properly follow the plain view doctrine.
Stop and FriskA stop is the brief detention of a person by
the police for questioning. A stop requires
reasonable suspicion.
A frisk is a pat-down or minimal search by
police to discover weapons. It is conducted
for the protection of the officer.
Stop and Frisk Cases
Stops and Frisks are governed by:
Reasonable suspicion
Terry v. Ohio (1968)
The “totality of the circumstances”
Stops and Frisks cannot be instigated by:
Tips from anonymous informants
Racial profiling
Plain View Doctrine Seizure can take place if:
Officer is lawfully in the area
Contraband must be in plain view
Office must immediately recognize the item as contraband
What is an arrest?
Arrest – to take into custody a person suspected of criminal activity; police may use only reasonable levels of force when making an arrest
