Extremist offender rehabilitation- Innovative, multiple and overlapping approaches as the path to success

Extremist offender rehabilitation: Innovative, multiple and overlapping approaches as the path to success

According to EUROPOL (2021), there were 119 completed, failed, and foiled terrorist attacks reported within the European Union (EU) and the United Kingdom (UK) in 2020, which resulted in the killing of 25 people.

Moreover, 634 individuals were arrested under suspicion of terrorism-related offences (EUROPOL, 2021), ending the year with a total of 507 convictions and acquittals for terrorist offences (EUROPOL, 2021; Home Office, 2021).

As some of these offenders had been previously convicted of terrorism or other crimes (EUROPOL, 2021), the need for comprehensive disengagement and reintegration efforts, following a thorough risk assessment process, is stressed. This concern was already emphasised in a previous report; EUROPOL (2020, p. 13) warned about the serious security threat represented by “individuals prone to criminal activities, including those currently imprisoned, who radicalise to violence and engage in terrorism”.

Adding to this growing challenge is the concern that several violent extremist and terrorist offenders (VETOs) are now/will soon be released from prison (EUROPOL, 2020). This fact gains special attention considering that, in 2020 alone, Europe suffered several attacks1 perpetrated by recently released individuals (EUROPOL, 2021).


The use of specific-oriented risk assessment instruments

Unsurprisingly, VETOs’ risk assessment within penitentiary settings has emerged as a particularly critical issue within the counter-terrorism architecture (Silke, 2014), especially in the EU (Fernandez & Lasala, 2021).

Although several risk assessment instruments have been developed in recent years (Radicalisation Awareness Network [RAN], 2019), there is a clear tendency to address some concepts in their broader sense, including ‘ideology’, ‘radicalisation’, ‘extremism’, and ‘terrorism’. In most instruments, the discussion of processes and pathways to radicalisation focusses on the same dynamics and risk factors, regardless of the relevant ideology (Khalil, Horgan, & Zeuthen, 2019; McCauley & Moskalenko, 2017).

However, RAN (Ranstorp, 2019; Sterkenberg, 2019) shows that Islamist and far-right extremism are marked by different narratives, ideologies, symbols, vocabulary, and recruitment places. Therefore, although several push/pull factors (including protective elements) are, in a wider frame, transversally concomitant to various radical/extremist ideologies, these should be explored (and adapted) in greater detail. This would mean an increasing compliance to inherent characteristics related to each type of extremism (e.g., Hardy, 2018; Klausen et al. 2020; Skleparis & Knudsen, 2020) and bearing in mind risk variations due to the gender dimension (e.g., Brown, 2019; Jacobsen, 2017; Pearson & Winterbotham, 2018).

In particular, the three risk assessment instruments (i.e., VERA 2R, ERG 22+, RRAP Toolset) analysed in-depth by RAN (Cornwall & Molenkamp, 2018) lacked unique dimensions/indicators related to ideology and gender.

Additionally, radicalisation risk assessment instruments tend to focus solely on VETOs’ evaluation, therefore neglecting offenders who might be vulnerable to/at risk of a cognitive increment of a radical viewpoint. Thus, to broaden the assessment scope into the prevention sphere, procedures should also encompass the identification of (and vulnerability to) radicalisation risk factors within the general offender population (such as the IRS Individual Radicalisation Screening, which is a part of the previously mentioned RRAP Toolset).


Mixed-method and cross-sectoral immersive training approach

The use of virtual-reality (VR) technology in the criminal justice system (CJS) has been gathering growing support, particularly in risk assessment. Cornet and Van Gelder (2020) affirm that VR can help improve the predictive validity of risk assessment instruments by, firstly, offering the possibility to observe behaviour in simulated environments. This is crucial, as de-Juan-Ripoll et al. (2018) state, because the first-person experience leads to more realistic behaviour.

Secondly, it can expose offenders to situations that elicit behaviour without risking the safety of others (Cornet & Van Gelder, 2020). This technology allows real-life scenarios in which frontline and technical staff directly face situations that call for decision-making. The benefits include improved learning results and better assessment of the behaviour of those involved.

Given that the assessment process requires data collection, namely through interviews with inmates and professionals, it is essential that staff acquire competencies that foster the use of developed instruments for these to be effective. Thus, VR-based learning techniques together with e-Learning training would be an innovative way of training different professionals in the field of risk assessment. Ultimately, this training approach will contribute to the successful rehabilitation of VETOs.


The critical importance of assessing and selecting non-institutional actors

It is by now unimaginable to successfully promote a reintegration programme without the support of civil society, as its critical role is widely recognised.

By analysing volunteers’ work in prison, research (Matt, 2015) emphasises the closeness of the volunteer-inmate relationship inside the CJS (whose final goal is to promote offenders’ successful rehabilitation). Nevertheless, external actors’ collaboration with the CJS should be carefully regulated, as it leads to “volunteering in criminal justice (being) increasingly constructed as a hazard that needs to be carefully managed with risk assessment and safeguarding regulations” (Corcoran & Grotz 2015, p. 95).

Although such non-institutional actors have been provided with training, there has not been particular interest in understanding how they are selected and screened, nor in setting criteria for this process. Even though the “basis of good practice is a multi-method selection process” (Aproximar, 2016, p. 21), organisations do not pay due attention to the selection of volunteers, having a relatively simple and insufficient procedure (Aproximar, 2016). Considering that volunteering has become a cornerstone of CJS’s work, the screening exercise is of utmost importance due to the key role of these actors in the disengagement and deradicalisation processes.


In addition, regarding the vetting process of volunteers contacting with the CJS (as illustrated in Figure 2) and, more particularly, offenders and ex-offenders, it is understood that: 38% of respondents reported checking the volunteer’s familiarity with the area; 37% stated carrying a formal background or criminal record check; 16% reported checking for appropriate qualification; 9% reported checking if volunteers have any professional experience; and 5% reported not having a vetting system in place (Matt, 2015).

Thus, it is necessary to set up a comprehensive selection process of non-institutional actors, entailing a thorough screening and assessment vetting criteria towards their recruitment and final selection (to work in close connection with the CJS). This need assumes even greater importance when dealing with inmates who are/were radicalised or are vulnerable/at risk of radicalisation (e.g., NGO staff members working in disengagement or deradicalisation initiatives and programmes). The criterion should be homogenous across countries and programmes in order to establish a coherent and rigorous framework.

The importance of collaboration between stakeholders

Although the relevance of multi-agency work in P/CVE initiatives has been recognised, it is also acknowledged to be “less well-established” than when dealing with other violent crimes (Sarma, 2019, p. 3).

Indeed, RAN (2019) identified barriers to information-sharing across agencies, namely confidentiality issues and cultures of secrecy. Such obstacles pose significant challenges to multi-agency work in the field of exit work (i.e., work focused on deradicalisation or disengagement). Nonetheless, this collaboration is crucial and should include various organisations, such as law enforcement agencies, prison and probation services, social and health services, youth workers and other civil society groups.

Non-institutional partners, such as non-governmental agencies, are critical to guaranteeing the prison-exit continuum as key exit work practitioners and their roles can go from assessing the needs of radicalised offenders and those vulnerable to radicalisation, to supporting their reintegration into society (Walkenshorst et al., 2019).


MIRAD: A new (and innovative) European initiative built on best practices

In this context, the European Commission, through its DG for Migration and Home Affairs (Internal Security Fund – Police) funded the MIRAD project.

MIRAD, which stands for “Multi-Ideological Radicalisation Assessment towards Disengagement”, aims to achieve a longitudinal implementation of risk assessment tools by building upon the Individual Radicalisation Screening (IRS)2.

Consequently, MIRAD intends to enhance proficiency in the application and management of specific and tailor-made radicalisation risk assessment tools, according to the ideology in question, among prison and probation staff and NGOs working closely with prison and probation services.

Taking into consideration NGOs/CSOs’ (working closely with the CJS) trustworthiness and credibility concerns, MIRAD also strives to expand the collaboration in the field of disengagement between governmental bodies and non-institutional organisations through capability and appropriateness assessments of the latter.

MIRAD will therefore foster the implementation of EU Directive 2016/680 (and beyond), thus receiving heightened attention from key sectoral decision-makers on cooperative relations among prison and probation administrations, judicial practitioners, as well as NGOs.

In short, MIRAD intends to sustainably influence not only the intellectual and policy debate but also the practical application of radicalisation risk assessment tools in prison and probation settings, with the support of NGOs involved within the CJS.

The MIRAD partnership joins public and private organisations that have been selected because of their expertise in the areas of Justice, penological and counter-terrorism research, education and training. It comprises research institutions, NGOs, private companies, and sectoral associations. There are seven EU Member States in the MIRAD project consortium that geographically represent Western (France3,4, Belgium5, Central (Poland6), Southern (Portugal7, Spain8, Greece9), and Eastern (Bulgaria10) Europe.
