The Dangerous Few (Psychology Documentary) - Real Stories. - Could the most effective method of crime prevention be a brain scan? This suggestion, the result of recent ground-breaking research, is investigated in the two films that comprise A Mind To Crime. The Dangerous Few examines the surprising claim from the USA that it is possible to identify children as young as four year’s old as potential criminals. Often prone to violence and stealing, children who suffer from Attention Deficit Disorder (ADD) have been found to have brain abnormalities consistent with those who turn to crime. Controversial treatments being developed are also revealed. Violent Minds, the second film, examines the brain abnormalities that affect different types of criminal, as well as investigating the links with drugs and the possibilities of brain damage inflicted before birth.
