is based on in-depth case studies on „several hundred individuals known
to be involved in, or closely associated with, violent extremist
activity“ ranging from fundraising to planning suicide bombings in
Britain.
The main findings include:
The majority are British nationals and the remainder, with a few
exceptions, are here legally. Around half were born in the UK, with
others migrating here later in life. Some of these fled traumatic
experiences and oppressive regimes and claimed UK asylum, but more came
to Britain to study or for family or economic reasons and became
radicalised many years after arriving.
Far from being religious zealots, a large number of those involved in
terrorism do not practise their faith regularly. Many lack religious
literacy and could actually be regarded as religious novices. Very few
have been brought up in strongly religious households, and there is a
higher than average proportion of converts. Some are involved in
drug-taking, drinking alcohol and visiting prostitutes. MI5 says there
is evidence that a well-established religious identity actually protects
against violent radicalisation.
