Vancouver Police Data

Main findings

  • a methodology was developed for police to collect information on apparent substance use, violence and mental health issues during the course of their duties
  • a brief card was completed following 936 incidents judged by the officer to have involved substance use
  • there were some problems with recording the total number of incidents in every shift but it is conservatively estimated that 33% of all incidents police dealt with involved substance use
  • overall, alcohol was the main substance involved in incidents followed closely by crack
  • alcohol was significantly more likely to be associated with violent incidents compared with other substance use
  • of all the districts, the Beat Enforcement Team in the Downtown Eastside recorded the lowest proportion of alcohol-related contacts and the highest proportion of drug-related contacts
  • there was evidence of a substantial increase in substance related incidents on a Welfare Wednesday
  • findings suggest that police officers may benefit from specialized training as substance-related contacts form such a large part of their work

Background

In assessing the extent to which drugs and alcohol are related to criminal activity, researchers often rely upon official data such as charge rates and convictions for substance-related offences. However, anecdotal evidence suggests that a large proportion of police incidents are due either directly (e.g. driving under the influence) or indirectly (e.g. a methamphetamine- or alcohol-fuelled assault) to the influence of substances.

The Vancouver Police Department project goals were to shed light on the types and quantities of drugs on the streets in Vancouver as well as to collect information on the number of incidents police respond to in which alcohol and/or drugs are a factor. Collecting information at the time of police incidents directly from the police themselves allows for a better understanding of the extent to which police are routinely facing substance-related incidents in their daily duties.

The VPD is organized into four main districts, plus the downtown core (see Figure 1). Each of the four Districts is composed of five teams (Alpha, Bravo, Charlie, Delta and Echo) which correspond to overlapping 11 hour shifts with the exception of the Delta shift which is 12 hours in duration, with all of the teams working on a four days on/four days off rotation. In addition, there is a specialized team of officers that work exclusively in the Downtown Eastside (DTES) called the Beat Enforcement Team (BET). This consists of four teams each with 12 members.

Data collection was carried out in August and November of 2009 and in the winter of 2010. Indicators included in the substance tracking card included basic demographic variables (gender, age, ethnicity), location of the incident, time of the incident, whether the subject had ingested substances recently and/or appeared under the influence, the reason for contact with the police, the level of violence presented, the nature and extent of substances found on the person, the purpose of the substance, and the response to both the substance and the subject.

This data provides much needed information regarding the extent to which drugs and alcohol are commonly involved in police-related incidents. This information also provides empirical evidence upon which VPD can shape their training and response policies. With relatively few variations, this methodology should also prove to be easily replicable in other jurisdictions both within and outside of Canada. Download the full report and data tables.

Demographics

Of the 936 substance-related contacts, approximately three-quarters (74 per cent) involved males, and over three-quarters (78 per cent) involved an individual whose primary residence was the City of Vancouver. The average age of the contacts was 33 years old with a range of 14 years old to 79 years old; the most common age was 25. Less than 5% of the data involved contact with a minor. Generally speaking then, substance-related contacts involved local adult males who lived in Vancouver. Unfortunately, given that the data was anonymous, the number of repeat contacts with the same individual could not be determined.

More Project Findings


Substance Related Contacts by Data Collection Period
The more frequent reports of drug and alcohol related contacts during the day in Time 3, as was previously predicted, is very likely explained by the commonly held police hypothesis that there is a causal relationship between the dissemination of welfare cheques to individuals with major mental health problems, including addictions, and the increase in police contacts involving substance use.

Substance Related Contacts and Violence
The expected relationship between violence and alcohol was found; one-quarter of instances with either confirmed alcohol use (26 per cent) or suspected alcohol use (25 per cent) indicated violence, whereas violence was only recorded in 13% of cases without alcohol use.

Substance Related Contacts
When based on the analysis of the individual 936 cards, at the time of the police contact, nearly three-quarters of the individuals (71 per cent) were identified as being under the influence of alcohol, while nearly one-third (31 per cent) were coded as under the influence of drugs. Less than one-tenth (7 per cent) was coded as under the influence of both drugs and alcohol.

Substance Related Contacts by District
The BET District and District Two were the least likely to have alcohol-related contacts, and the most likely to have contacts with individuals under the influence or in possession of crack. The most common substance in the other districts was alcohol. Nonetheless, in these other Districts, it was unexpected that after alcohol, when a contact was impaired by a drug or in possession of a drug, the most common substance was crack.

Component Details

Over a period of many months, and with the contributions and insight of VPD, several revisions to the methodology and the data collection instruments were undertaken. In addition, data collection took place during four different calendar periods. To avoid putting disproportionate responsibilities on only a few officers selected through sampling, all officers working during the eight-day data collection period were asked to participate in data collection. Each officer was provided 15 data collection cards in each of four envelopes to be collected during each of their four shifts. Substance related information consisted of: whether the person of interest was suspected or confirmed to be under the influence of alcohol and drugs; and, specifically what substances were present. In addition, reasons for the police contact were recorded using the most common responses recorded on the PRIME system as a guideline.

As well as the type of substance and the reason for contact, the VPD was interested in the presence and degree of violence officers experienced during their contacts with the public. The degree of violence was measured as low, moderate, or high corresponding to the categories of simple or level one assault, assault causing bodily harm or level two assault, and level three; aggravated assault, a coding system familiar to the police.

Given the essential need to avoid a bulky card that would interfere with officer’s ability to both access and complete the card quickly, the card was restricted to four information sections: substance contact demographics (district, time, and date); person of interest demographics (gender, age, residential community); contact information (reason for contact, presence of violence); and substance related information (alcohol or specific type of drug). The back of the card was left blank to allow the recording of additional commentary (see research instrument).

Prior to data collection, this project received approval from the VPD and research ethics approval from the University of the Fraser Valley’s Research Ethics Board. The data was collected during a pre-test period followed by three periods of data collection (identified as Times 1 through 3). While the eight-day data collection period in the first two actual phases of the project deliberately avoided Welfare Wednesday to avoid potentially skewing the data, Time 3 specifically occurred over this period. The latter period facilitated an empirical assessment of the above hypothesized relationship between Welfare Wednesday and both the distinctive types and general quantities of substance-related police contacts.

VPD Districts

District One includes the West End, Yaletown, Coal Harbour, and the Central Business District, including such locations as GM Place, Canada Place, BC Place, and the Trade and Convention Centre. This area is populated by approximately 300,000 people during the day. However, during celebrations, such as the 'Celebration of Light' (fireworks), the night-time population substantially increases.

District Two consists of the areas of Grandview-Woodlands, Hastings Sunrise, and Strathcona. Each of these areas has a Community Policing Centre as the district emphasizes the principles of problem-oriented policing. District Two also operates a Waterfront Team, and foot- and bicycle-beat officers.

District Three is located in the southeast of Vancouver covering the areas of Mount Pleasant, Kensington-Cedar Cottage, Renfrew-Collingwood, Sunset, Victoria-Fraserview, and Killarney. Within District Three are Neighbourhood Integrated Service Teams who are tasked with responding to identified community problems such as maintenance of buildings, public safety, and problem tenants. District Three also operates two Community Policing Centres.

District Four is located in the southwest of Vancouver, encompassing a large area of West Point Grey, Kitsilano, Fairview, Dunbar Southlands, Arbutus Ridge, Shaughnessy, South Cambie, Riley Park, Musqueam, Kerrisdale, Oakridge, and Marpole. District Four represents almost half (48%) of the geographical area of Vancouver, with approximately 36% of the residents. There are 125 officers working rotating shifts in this district. Their tasks commonly include property-related incidents such as theft, house alarms, or break and enters. There is one Community Policing Centre in this region, staffed by approximately 90 volunteers.

Component Summary

The Vancouver Police Department component of the BC Alcohol and Other Drug Monitoring Project aims to shed light on the number of incidents police respond to in which alcohol and other drugs are a factor. Police data can be an important indicator of the impact of substance use on communities as well as on service provision by law enforcement agencies.
