**Abstract.** Crime is a reality that effects everyone in the world. Even developed countries such as the United Kingdom, Canada and Germany are not exempted from crime occurrences. Although these indicators are substantially less than developing countries such as South Africa, the existence of crime is a worldwide phenomenon. In this paper we explore the extent to which social media, in particular Facebook are used in the fight against crime.

The study adopts a social technical approach in its investigation, considering the symbiotic relationship between communities (the organisation), Facebook and the utilisation of Facebook to complete tasks (technical subsystem), team members and structure to report crime in virtual communities (social subsystem) and current governance structures (environmental system). Based on a study of 297 crime fighting Facebook communities in South Africa, we found a positive correlation between the number of Facebook crime fighting communities per region and the crime rates for a particular region. Furthermore, we noticed that the regions with the most crime communities also had the most Internet connectivity per household. Both findings are indicative of a functional symbiotic relationship between the technical subsystem and the social subsystem. However, it highlights the fact that these structures are initiated by communities therefore lacking strong intervention from the environmental system, in this instance governmental bodies. We propose that governmental agencies formally recognise social media platforms as social crime fighting tool. Secondly, we suggest that governmental entities should focus on infrastructure related challenges as part of their attempt to combat crime.

**Keywords:** Social Media, Crime Prevention, Facebook, Cohesive Community.

## 1 Introduction

Crime is a reality that affects everyone in the world, irrespective of their developmental classification status. Although a substantial difference between the number of crime occurrences and crime type exist between countries from different developmental classifications, the fact remains that crime occur. For example, when violent crimes (such as murder) are investigated, a country such as South Africa is listed as having three cities in the top 50 in 2017/2018 [1]. On the other hand, developed countries such as United Kingdom, Canada or Germany do not appear on the list.
In a developing country such as South Africa, local authorities have called for local
communities to work together to actively participate to combat crime. After the release
of the 2014/2015 crime statistics the local Police Minister, Nkosinathi Nhleko, said that
businesses, communities and the police need to work together to curtail crime in South
Africa [2]. This call is a repeat of an earlier call by the Member of the Executive Council
(MEC), Nomusa Dube-Ncube, who expressed his shock at the brutal killing of one of
its members [3]. He stated that “*It is incidents such as this heinous crime that remind us that crime and violence remain a grave challenge in our communities and that as society we need to galvanise each other's strength to isolate the criminal elements that threaten social cohesion and harmony in our communities*” [3].

Communities have been ‘taking up the fight’ against crime in the form of Social Networking Crime Fighting communities – specifically Facebook. These “crime fighting communities” were established with the specific purpose to combat crime in the area. In [4] it was reported how a CPF uses Facebook to execute their mandate and found that the CPF community shares two types of information: firstly information relating to the building of a cohesive community. Secondly, information related to the creating of awareness of crime in the area. In a second study [5] investigated how Facebook is used to locate people who have been reported missing by family or friends in South Africa. Graphs were used to indicate differentiated roles of the Facebook communities. Whilst some communities act mainly as originators of the messages, others act more as distributors or end points of the messages.

On an international level similar studies, where communities act both as originators
and distributors of messages to contribute to a specific cause, have been conducted.
One such instance was the utilisation of a Facebook group to assist with the finding of
an Australian woman, Gillian “Jill” Meagher that went missing after an evening out.
Although the study reported on the “*collective practices of meaning-making in response to public crime events*” [6], it was a good example of how Facebook communities were
utilised. This is in line with the findings of Hattingh [4] and Powell et al. [6] that con-
firms that social networking sites, such as Facebook, are used in the fight against crime
and crime related activities.

This paper will extend on previous studies by answering questions regarding the
representation and focus of communities on Facebook and the probable correlation be-
tween said communities and crime levels. The study will furthermore add to the existing
understanding of the use of technology and community participation in the fight against
crime in developing countries. This will be achieved through a structured review (using
specific keywords) of Facebook communities/groups. The study is based on a socio-
technical approach as the main theoretical underpinning considering the assumed sym-
biotic relationship between communities (the organisation), Facebook and utilization
of the Facebook environment to complete tasks (technical subsystem), team members
and structure in the virtual community (social subsystem) and current governance struc-
tures (the environment). This will hopefully expose the weak points in the socio-tech-
nical value chain.

The remainder of the paper follows the following structure: in section 2 we provide
an introduction to the socio-technical theory [7]. In section 3 the literature will be pre-
sented in accordance with the socio-technical theory introducing the environment, the
organizational system and the social and technical subsystems. The approach to this
study is discussed in section 4 where after we discuss the results in section 5. We con-
clude the study in section 6.

## 2 Social Technical Theory

Socio-technical theory focus on the interrelationship between technical subsystems and social subsystems with the main objective of creating a balanced, effective, symbiotic relationship in the context of an organisation or social system governed by the rules and regulations of a bigger environmental system [7]. It is postulated that, the more effective the interrelationship, the greater the benefits as a result of the interaction between the subsystems [7]. Socio-technical systems refer to the interaction between team members in a social system or organisation whilst the technical system refers to the utilisation of technical tools and techniques that enable the interaction (referred to as tasks) [7].

In the instance of Facebook communities, the organisation sub system refers to a
virtual community, i.e. CPF in Facebook. The community interacts within the virtual
community through the utilisation of Facebook, in this instance the social networking
site (or Web 2.0 tool) [8] enabling connectivity and information sharing amongst mem-
bers. The virtual community share the same values, i.e. to contribute to a safer commu-
nity through collaboration. These values are built into the use and capabilities of tech-
nology (the technical subsystem). For example, strict security measures by means of
membership only groups can be enforced in order to vet members for membership eli-
gibility prior to joining the group. As a result, potential members with criminal intent
is identified prior to the allowing membership.

This virtual FB community is a classic example of a self-organising community [9]
with a shared interest of contributing to a safer local community. The environmental
system provides the overall governance and unspoken rules to the other systems/sub-
systems (organisation, technical and social). For example, the prevention and possible
prosecution of ‘hate speech’ when using the virtual community is governed by the in-
herent rules and regulations of the local government.

## 3 The Organisational System: Cohesive Communities

The causes, impact and response to crime as well as the relationship between these
factors have been a much researched area internationally [10–12]. One study of much
importance is research conducted by Leverentz and Williams [10] that investigated how
physical communities react to, and subsequently attempt to control crime by adopting
various crime-control strategies. They have identified three responses or strategies to
crime namely “reliance on public alliances, tentative public-parochial partners and
grassroots public engagement”. Bendler et al [13] has investigated the utilisation of
social media data (Twitter) to predict crime related activities using predictive analysis
and virtually published their results as part of a “virtual neighborhood watch” group.
Using predictive analysis to predict crime based on historic events are perceived by
many authors as key to combat future crime.

Research on the impact of crime in South Africa has increased significantly, partic-
ularly with publications such as this one, dedicated to report on the state of, and the
progress in the fight against crime in South Africa. Crime patterns are not evenly dis-
tributed which makes it difficult to predict and manage [14]. Recent statistics indicated
that the Western Cape has the highest level of reported crime experience at 9.7%, fol-
lowed by Gauteng with 9.1%. The lowest level of reported crime experienced was in
Limpopo with 4.2%. There has been a focus on two main areas in the fight against
crime: Cohesive community participation and the use of technology. A cohesive com-
munity is defined as a community where “there is a common vision and sense of be-
longing for all communities, the diversity of people’s different backgrounds and cir-
cumstances is appreciated and positively valued” [15]. The cohesive community is also
referred to as the organisation in the social-technical theory, whilst the use of technol-
ogy forms part of the technical subsystem. In the sections to follow each of these two
areas or subsystems will be elaborated upon. However, first the environment in which
these two subsystems exist need to be considered and will be discussed next.

**3.1 Environment: Governance Structures.**

Any community initiative needs to occur within the confines of the law. This include
community initiatives that support the fight of crime. In support of the CPF initiative
of the SAPS, Choi, Lee and Chun [16] state that the police force (the environmental
system) needed the support of communities in order to be effective in providing com-
munity safety. In their extensive literature survey they identify a number of factors that
motivate citizens to participate in crime prevention activities: (1) confidence in the po-
lice, (2) personal safety, (3) attachment to the area, and (4) crime problems in the com-
munity.

The importance of CPFs are further highlighted in research by Rey [17] where the
author focused on the identification and measuring of online crime prevention commu-
nities to ensure the healthy (and therefore effective) only communities.

Even though the South African Police Service (SAPS) has a social media presence,
the platforms are only used to engage with citizens. They urge citizens not to use social
media platforms to report a crime as the type of information required (normally by an
operator) is too specific and the response time to these posts cannot be guaranteed [18].

**3.2 Social subsystem: Using Cohesive Communities to Combat Crime.**

Sampson and Raudenbush [15] found that cohesive communities display lower levels
of crime and social disorder due to the collective effort by the community to meet their
common goal. Lee [19] found that socioeconomic status, lifestyle and neighborhood
characteristics have no influence on the possibility of be-coming a victim of violent
crime, such as robbery and assault, when one is part of a cohesive community because
of high levels of social control. Even though Roberts and Gordon and Gordon [12] found that social cohesion can pull citizens apart due to the fear of crime, it was found in a previous study [4] that community cohesion had a positive effect on the community. This was also supported by an earlier study conducted by Wedlock [11] found that there was a 3% decrease in residential burglary, 4% decrease in motor theft, 2% decrease in theft from motor vehicles and 3% decrease in violent crime with every 1% increase of sense of community experienced by neighborhood communities.

## 3.3 Technical subsystem: Using Technology to Analyse and Predict Crime.

The use of technology in the fight against crime can take two forms: using technology in the analysis of crime statistics and using it to predict the possibility of crime occurrence. Firstly an example of the former is the interactive crime statistics map(s) based on the annual crime statistics released by the SAPS and created by the Institute for Security Studies. The visual representation of the SAPS crime statistics allow citizens to view the crime trends since 2004 per category, per municipality and per police station. In addition to the SAPS' statistics the Crime Hub provides information on public violence per region [20].

Secondly technology allows for the prediction of crime. Cherian and Dawson [21] employed machine learning and other statistical techniques to classify and predict average crime incidents in the coming weeks and months. Also, the illustrative study of Lancaster and Kamman [22] proposed a data linking methodology that can analyse the demographic characteristics of police precincts to predict the murder rate at precinct level. This methodology allows for more sophisticated measurements to investigate certain associations between the risk factors identified in the ecological framework (consisting of the individual, relationship, community and societal). One of the most important indicators that could be identified using this methodology will be that between crime and the community which includes "feelings of belonging or perceptions of social or group integration, and a willingness to show solidarity". This connects the "technology" aspect to the community aspect.

The previous discussions have considered community participation independent of the usage of technology to combat crime. Web 2.0 technologies and more specifically social networking platforms allows normal citizens to partake of the content creation platforms, especially in the form of social networking participation. In the following section we will discuss how communities utilize Web 2.0 technologies to combat crime.

## 3.4 Interaction between social and technical subsystems: Communities using Web 2.0 technology to combat crime.

The increased Internet access of South Africans have enabled more citizens to take part in digital activities. According to World Wide Worx and Ornico's South African Social Media Landscape 2018 study there has been a sharp increase in social media uptake. 31% (16.74 million) of all South Africans now use WhatsApp and 26% (14.04 million)
of all South Africans use Facebook [8]. Social networking platforms such as Facebook provide an ideal tool for citizens to participate in the fight against crime. Citizens can now “post” about an event or upload photos and videos with GPS coordinates without much effort. The most prominent use of social media in the fight against crime was during the Boston Marathon bombings where it was used to identify the bombers successfully. In response to this successful use of social media McCullagh [23] stated that “a traditional manhunt becomes something much different in the age of Twitter, Instagram, and face recognition”.

Twitter has been used in the fight against crime. Wang, Gerber and Brown [24] developed a model that predicts hit-and-run incidents uniformly across all days. Bendler, Brandt, Wagner, and Neuman's [13] research focused on how Twitter can be used to create a sort of virtual neighborhood watch (NHW) which will create a secure environment for tourists and residents. It will also help the police and authorities in identifying patrol spots. The latter is accomplished through the live prediction from media streams. Gerber [25] further analysed the use of Twitter to predict crime by analysing the tweets using kernel density estimation. He identified a number of “performance bottlenecks” that could have an impact on the use of Twitter in an actual decision support system.

In South Africa Featherstone [26] investigated how Twitter can make communication more useful in terms of data gathering, prediction and plotting broader patterns. She showed in a second paper how Twitter can be used to identify vehicle descriptions to assist in reducing or predicting crime [27].

In [14] the Internet access at home, at work, using mobile devices and at other facilities were reported. It should be noted that a citizen can access the Internet at more than one location, therefore the total percentage of Internet access can exceed 100%. Taking this into account, Gauteng has the highest level of Internet access with 119.7% followed by Western Cape with 113%, Kwa-Zulu Natal with 76.7%, Free State with 75.4%, Mpumalanga with 75.1%, Northern Cape with 73.4%, Eastern Cape with 69%, North West with 67.7% and Limpopo with lowest level of access at 49.4%.

Mobile Internet access is by far the most accessible option of accessing the Internet as it can happen anytime, anywhere. This is not surprising as currently there are 20.8 million smart phone users in South Africa [28].

## 4 Research Methodology

The aim of this research project is to explore the extent to which communities fight crime using Facebook groups/pages as part of a bigger socio-technical system. In reaching the aim the following questions need to be answered: (1) To what extent are crime fighting communities represented on Facebook? (2) What is the focus of these communities? (3) Is there a correlation between the number of crime fighting Facebook communities, the membership rate of the crime fighting Facebook communities and the crime rate on provincial level? (4) What are the weak areas considering the various subsystems (organisation, technical, social and environmental) in the bigger socio-technical system?
In answering the first research question the researchers conducted a review of Face-
book communities between 22 March and 30 May 2016. Facebook’s built-in search
engine was used to search the following key words to identify “crime fighting commu-
nities” on Facebook: “CPF”, “Community polic (to pick up “Policing” and “Police”)”,
“Crime”, “Concerned citizens”, “Crisis”, “Emergency”, “Intelligence bureau”, “Neigh-
borhood watch”. The search was restricted to South African groups/pages that were in
English. The keywords were derived by following a snowball sampling approach,
where the first keyword “CFP” derived from the first study [4] was used as the initial
community. The researchers then observed which pages/groups were linked to the inti-
tial community to derive the remaining keywords.

The researchers recorded, in an MS Excel spreadsheet, the keyword used in the
search, whether it was a group or page, the title of the group/page, membership num-
bers, the description of the group/page, which province the group/page covered and
whether mention was made of any other means of communication, like WhatsApp and
interesting observations. The researchers also captured the latitude and longitude of
each area obtained from the LatLong.net in the spreadsheet which helped them to plot
all the Facebook communities that were identified through the search, on a map of
South Africa. This map is generated by MS Excel Powerview and is illustrated in Figure
1. The size of the bubble is related to the number of communities in that particular area.
The overlapping bubbles indicate the concentration of members in a specific area as an
individual can be a member of more than one community and the number of commu-
nities in a very small area.

<figure><img src="image_2.png" /><figcaption>Fig. 1. Facebook communities in South Africa</figcaption></figure>

In order to answer the second research question thematic content analysis [26] was used
to analyse the descriptions (as stated on their Facebook profiles) of the top member
groups, as well as all the posts for the past week (6 July 2016 – 13 July 2016) which
will be used to obtain an understanding of the focus of each group/page. In order to
answer the third research question the researchers utilised the results illustrated in Fig-
ure 1. No further data was gathered to answer the fourth research question as data gath-
ered to answer question one to three will be used to apply to the concept of a socio-
technical system.
# 5 Discussion of Results

The aim of this paper was four-fold: firstly, to identify the number of crime fighting communities on Facebook in South Africa, secondly to understand the focus of said communities thirdly to determine if there is any correlation between the communities and the crime levels and fourthly to use the data gathered in order to identify possible weak links in the various subsystems of the socio-technical system. The results will be discussed in accordance with these question.

## 5.1 The number of “crime fighting communities” on Facebook in SA

In meeting the first aim, the Facebook search, using the keywords stated above, have revealed 297 dedicated crime fighting Facebook communities throughout South Africa. The Eastern Cape has 18 communities (91 364 members), Free State has 7 communities (12 645 members), Gauteng has 114 communities (299 336 members), Kwa Zulu Natal has 29 communities (65 935 members), Mpumalanga has 10 communities (16 884 members), North West has 11 communities (23 44 members), Western Cape has 71 communities (153 712 members) and Limpopo has 6 communities (3820 members). Furthermore, there were 31 national communities which are not associated with any specific area/province. In total more than 1.1 million in South Africans belong to crime fighting communities. (It is possible for a citizen to belong to more than one community simultaneously). The communities considered is by no means an exhaustive list of crime fighting communities, it was observed that a number of the communities also had websites, WhatsApp groups, Zello accounts, Twitter accounts or use “old fashioned” citizen band radios. The usage of multiple (mainly) social media platforms by the communities are in line with a previous study by Hattingh [4] where a single CPF used multiple platforms.

Although the number of communities dedicated to crime in SA was impressive the most interesting finding of this study is that, by using the keyword listed previously, no Facebook crime fighting communities were found for the Northern Cape Province.

## 5.2 The focus of the “crime fighting” Facebook communities

Facebook Communities typically had a description that invites community members to partake in the fight against crime. From the quotes below, it can be seen that these communities were dedicated to “fighting crime”.

> "Reporting and fighting crime - by the community for the community" [Concerned Citizens page, GP]

Communities are now standing together to make headway in the fight against crime by supporting one another. The following post illustrates the call from the community for the community to assist.

> "The Time Has Come......we have to all pull together and watch over each Other. Crime is out of hand and out of touch. Everyone needs an immediate update of Crime and emergencies in your Area, so that anyone in the Vicinity can Respond and assist immediately, like all Good and caring Citizens should. ..." [Crime group, KZN]
In addition to identifying the “mission” of each Facebook community by reviewing their descriptions, a total of 210 posts were reviewed across the top five communities. The analysis have generated a number of themes which supported those that have been identified in a previous study [4] which included “reporting”, “awareness”, “alertness”, and “update”. The cohesive community principle of cohesive community as introduced in [4] was extended by requesting “assistance” from the community members. For example, community input was requested on a vehicle accident that occurred (assistance theme), general information regarding awareness tips (awareness theme), information sharing regarding activities in the community to “Be On the LookOut” (BOLO) for armed robbery suspects, missing people, suspects involved with a murder/robber/vehicle theft etc. (alertness theme). The reporting and updating activities in followed in the same vein as previous studies. However, there have been much more updates provided to the community members compared to the first study. 12% of the posts were updates to “crime events” that occurred. This includes updates regarding armed robberies, vehicle theft, ATM bombings etc. Research has shown that updates are important and seen as “rewards” for communities when communities help by providing the intelligence when solving a problem [4].

The data revealed a few more crime categories identified compared to the first study. This includes posts related to drugs which includes updates on successful drug busts but also awareness regarding the dangers of using drugs and who to contact when help is needed with regards to rehabilitation. Furthermore, hi-jacking's, ATM bombing and public violence/protests were the other new crime categories that were identified. The new crime categories can be a result of firstly, the larger “affected area” as three of the five groups under consideration were “National groups” (i.e. not related to a specific area) and secondly due to the time the snapshot of posts were taken – just before the government elections.

Finally, even though three of the five groups were “National”, the theme of cohesive community, identified in the previous study persist as there were 73 information sharing posts which included posts with photos/videos/newspaper articles on incidents such as drug busts, substation being on fire, road collisions that happened in the past week etc. These posts were not updates per say (an update is defined as a response to a specific incident) but it kept the communities informed about activities in their area/surrounding areas.

## 5.3 Correlation between the communities and the crime levels

When comparing the number of communities to the crime statistics as presented above, it shows that Limpopo province has the lowest level of experienced crime events [14]. Limpopo only has six crime fighting communities with a mere 3820 members in total. With a population of more than 5.72 million [14] people the Facebook crime fighting communities are only accounting for 0.0007% of the population of Limpopo. One reason for this might be that Limpopo has the lowest Internet access level of 49.4% [14].

On the opposite end of the scale, Gauteng, the smallest province have a total of 114 different crime fighting Facebook communities, with a total membership of more than
299 000. Gauteng also has the second highest experienced crime level and has the larg-
est Internet access level. The high crime rate, high population and high Internet access
level might explain why Gauteng has by far the most crime fighting communities on
Facebook, in South Africa. It can therefore be argued that there is a correlation between
the crime levels, the number of social media crime fighting communities and to a lesser
extent the availability of Internet access in the province.

**5.4 Possible weak links in the various subsystems of the socio-technical system**

Based on the discussion above it is therefore evident, and safe to say, that the organisa-
tion system is a strong, functional subsystem although it was anticipated that a stronger
focus on the objective of crime fighting would prevail. The majority of the communities
work together with the SAPS and security companies (as illustrated in the quote below)
in the fight against crime.

"Independent Group to report Crime, creating a vigilant community helping each other bringing the Community, Police, Sector Police and Security companies together in fighting crime". [Crime group, WC].

Figure 2 illustrates the socio-technical system of crime fighting communities on Fa-
cebook.

<figure><img src="image_3.png" /><figcaption>Fig. 2. Facebook as a socio-technical used by crime fighting communities</figcaption></figure>

However, the utilisation of the technical subsystem by means of a computer mediated
communication platform (Facebook) has enabled members to contribute to a greater,
common cause despite geographical dispersed challenges.

The technical subsystem, (the social media platform, in this instance Face-book), is
an effective tool to use in the fight against crime. Internationally social media platforms
are used as a crime prevention tool [29]. Citizens of South Africa, through the utilization
of Facebook Communities and other social media platforms have already showed a
willingness to work with the SAPS and other security organisations, however the im-
pression is that this initiative is driven from the citizens' side. The environmental sys-
tem (SAPS and other governmental institutions) perhaps need to formally recognize the
potential of social media as a crime fighting tool and dedicate resources to assist citizens
in the monitoring of social media crime reports and deploy the necessary members to
act on these reports. If this issue can be addressed it can contribute to a stronger envi-
ronmental subsystem to the benefit of the organisation subsystem. Social media plat-
forms or the technical subsystem is an inexpensive medium to formulate a crime
fighting network.

6 Conclusion

This paper has confirmed and extended previous findings on the successful use of Fa-
cebook as a crime fighting tool by communities in South Africa. The paper has found
that 297 Facebook communities, over eight provinces, exist that are dedicated to the
fight against crime. The findings indicated a correlation between the number of crime
communities and crime rates. As the power of social media as a crime fighting and
prevention tool has been confirmed in this study and previous studies, it is recommend
that the SAPS formally recognise and adopt social media platforms as a crime fighting
and prevention tool. Government needs to develop a formal strategy, incorporating all
relevant departments, to enable citizens through the provision of affordable data and
infrastructure to participate in the fight against crime. It is envisaged that, if these chal-
lenges are addressed, the environmental subsystem, which have been identified as a
weak link, will contributed to a stronger, much more effective socio-technical system.
