C/S/43. What limitations exist in psycho biological explanations of crime?

The extent of the limitations of psycho biological explanations of crime will be coming to the forefront, because of the Criminal Justice Act 2003 (CJA). The main implication of the CJA was to expand the powers of the police to retain DNA samples on all suspects, even if acquitted. This database allows for the police to profile the individuals contained within for future crimes; as well as genetic markers and indicators. This discussion will explore the problems of identifying psycho biological indicators of criminally predisposed by highlighting that prejudice is prevalent in the Criminal Justice System. This will corrupt the data and the samples that are retained and not just the profiles; therefore further testing and in depth analysis could occur to identify those traits which 'signify' a criminal, i.e. similar DNA traits lead to profiling on the basis of race or genetic makeup which could lead promotion of racism and segregation of those with so-called 'criminal tendencies'.
