It could just be an additional test couldn't it? Genetic testing for susceptibility to aggression and violence

Much of the current genetic research into aggressive and violent behavior focuses on young people and might appear to offer the hope of targeted prediction and intervention. In the UK data are collected on children from various agencies and collated to produce at risk of offending identities used to justify intervention. Information from behavioral genetic tests could conceivably be included. Regulatory frameworks for collecting, storing and using information from DNA samples differ between the health service and the police particularly in the need for consent and the treatment of children. This paper draws on discussions with professionals involved with problem young people to consider their views on the utility of genetic research for tackling violent/aggressive behavior and the impact an identification of genetic susceptibility might have on their clients.
