Early theories about criminal behaviour suggested might be physical difference in criminal and non-criminal enable us to identify individuals before commiting a crime.

Lombroso; physical features that criminals typically had narrow, sloping forehead, prominent eye ridges, large ears & protruding chin.

Brain Scanning opened new way to research differences in criminals and non-criminals. Might be specific areas of brain are different in criminals, may predispose individuals to violent behaviour.
Animal research and studies of people w/ brain damage have found this.
Raine et al. focused on particular group criminals = Individuals committing a murder & entered plea of not guilty by reason of insanity (NGRI).
Proposed on basis of previous research, that seriously violent individuals:

Have brain dysfunction in prefrontal cortex, angular gyrus, amygdala, hippocampus, thalamus and corpus callosum.
Not have brain dysfunction in areas of brain that have been implicated in mental illnesses, not previously related to violence; caudate,putamen, globus pallidus, midbrain, cerebellum.
