Last week the Guardian uncovered a report by MI5 suggesting there is no single pathway to Islamic extremism. What a surprise! And in a further deconstruction of preconceptions, the report found evidence that a well-established religious identity actually protects against violent radicalisation. If this is the case, what are the implications for racial and religious profiling? The report clearly dismantles any assumptions that can be made about the identity, background and religiosity of a would-be terrorist. The UK’s Muslim population is a mere 2.8% but is so ethnically diverse that the government could cynically use this report to sanction the continuing infringement of civil liberties of the entire population through ID cards, surveillance and so on. The sounding the death knell for racial profiling is something to celebrate, but I wonder whether my optimism is premature. Adam Khan, 28, from North London also has his reservations, after repeatedly being stopped and interrogated under schedule 7 of the Terrorism Act 2000 when trying to return to the UK.
