Prevent requires trust in order to be effective. The greatest threat to that trust comes from anecdotes of this type. Mohammadi’s case is not the only such example. Those who work in the Prevent programme will tell you that many of the cases which have made headlines are not all they seem. The Government is currently conducting a further review of Prevent. An authoritative rapid rebuttal process that can address such stories before they can be used by far left and Islamist groups who would prefer that we did not fight terrorism at all must be one of its recommendations.
