Predicting the Risk of Future Terrorism: Lessons for Mental Health Experts from the Benbrika Case.

Risk assessment is an important component of judicial decision-making in many areas of the law. In Australia, those convicted of terrorist offences may be the subject of continued detention in prison or extended supervision in the community if there is an "unacceptable risk" of them committing future terrorism offences. Forensic psychologists and psychiatrists may provide evidence of risk through identifying and measuring risk factors with the aid of tools that use scales based on statistical or actuarial risk prediction. This column focuses on criticisms of the use of the second revision of the Violent Extremism Risk Assessment tool (VERA-2R) in determining the risk of future terrorist acts.
