My interest in security was sparked when I was at university and my beloved uncle Phil was kidnapped in Colombia. Suddenly, I was thrust into a world of private security companies and response consultants, and felt like an extra on a Hollywood movie set. It led me to ask a few basic questions: who had taken him? Why would they want him? How would we get him back? And, importantly, what could be done to help others who might suffer the same anguish as his family did for 7 long months?

I now dedicate part of my life to the final challenge – running a small charity called Hostage UK, which supports the families of hostages during a kidnap and the family and hostage post-release. We offer pastoral care, put the families in touch with others who have been through the same experience, provide them with any professional support they might need, and offer advice and guidance on how best they can cope with their experience.

When I am not running Hostage UK, I am Research and Policy Director at the Institute for Strategic Dialogue. There, I oversee our work on extremism and counter-terrorism, where – amongst other things – we have recently launched the Against Violent Extremism Network (AVE) to bring together former extremists with the survivors of violent extremist attacks to work to counter radicalization and help reintegrate extremists looking to leave their movements.

I have been reflecting on where these two worlds collide, and it strikes me that there are lessons to be learned from the reintegration of hostages and former extremists back into their family environments. I am not seeking to make light of the experiences of hostages, or draw parallels between their suffering and the choices of extremists. But if we look at the specific challenge of reintegration, there are some parallels. Here are five lessons that those looking to reintegrate former extremists could learn from our work at Hostage UK.

First, both the hostage and the family experience extreme forms of trauma. Hostages always say that their family experiences more stress than they do, because they always have the luxury of knowing whether they are alive or dead. When the hostage is released, the family is often not in a position to support fully, because they are in need of support themselves.

Second, the hostage and the family go through different experiences, and this can mean that they feel estranged from one another when the hostage returns.

Third, while the hostage has been away, the family has inevitably moved on. It is so often the main breadwinner who has been taken, and in their absence their wife (it is usually a female partner at home) has assumed the position of head of household, taken on responsibility for finances, and usurped the hostage’s role within the family. This can make reintegration difficult, as the hostage will not be able simply to slot back in and might feel excluded. It is mainly for this reason that there can be higher than average incidences of divorce post-release.

Fourth, the hostage may have experienced things during their captivity that they do not wish to share with their families due to a sense of shame and an inability to communicate. This only increases the sense of division between them and their family members.

Fifth, there is so often a reluctance on the part of both the former hostage and their family to accept that they might need help and support.

Applying these lessons across former hostages and former extremists may not be entirely intuitive. But it is vital to acknowledge that extremism – like kidnapping – is a human crime with a human solution, of which families must be a part. It is vital that these lessons are learned.
