CEP Strategic Advisor Liam Duffy writes: "In his independent review of Prevent, published last week, William Shawcross came to the same conclusion: the overemphasis on vulnerability in the process of radicalisation strips individuals of their agency, obscures reality and sucks the politics out of political violence."

"Research by the Counter Extremism Project found that police sources had been told that the Abedis had to have known that Hashem and Salman were becoming more radical. After the attack, a mutual friend said the pair had discussed and expressed support for Isis."

CEP resources and experts quoted throughout: "Read William Shawcross CVO, the Independent Reviewer of Prevent’s report and how the government is responding to the recommendations outlined in the report."

"The recommendation was welcomed by Professor Ian Acheson, a senior adviser to the Counter-Extremism Project and a former prisoner governor.

'It’s the idea that everyone can be redeemed that is infecting the approach, which is always looking for improvement and for reduction of risk,' he said.

'It means officials are particularly vulnerable to psychologically sophisticated, ideologically-motivated terrorists. The terrorists don’t have to be particularly intelligent, they just have to be cunning and adept at hiding their true motivations.'"

"Home Office officials responsible for the decision to fund groups that have spread Islamic extremism should be sacked, according to a former counterterrorism official.

Professor Ian Acheson, who is now a senior adviser to the Counter Extremism Project, said the UK should take a far tougher approach to non-violent Islamist groups who 'undermine social cohesion' by spreading hatred."

"Prof. Ian Acheson, a senior adviser to the Counter Extremism Project, which contributed to the long-delayed Shawcross review of the government’s anti-extremism Prevent program due to be released this week, called for a stricter approach to Muslim groups that 'undermine social cohesion.'"

'We don’t have the robust challenge we should have, because everyone is so afraid of being racist,' warned Professor Ian Acheson, a former prison governor and senior advisor to the Counter Extremism Project, an international policy organisation."

"Ian Acheson, Senior Advisor at the Counter Extremism Project, agreed Prevent needed to change. 

He tweeted today: 'As the Home Secretary says and some of us have been saying for a while, Prevent has morphed into a strategy that awards a (convenient) completely false equivalence between Islamist and XRW threat and is swamped by mission creep. Time for a reset.'"

CEP Senior Advisor Ian Acheson writes: "In the last five years there have been at least five terrorist acts committed in this country by violent extremists who have had previous contact with Prevent. Once is too many. Five events that outraged and terrified the public, and left six people dead and scores with life changing injuries, is a trend that can’t be ignored."
