The paper provides a review of current issues relating to the use of DNA profiling in
forensic science. A short historical section gives the main statistical milestones that
occurred during a rapid development of DNA technology and operational uses.
Greater detail is then provided for interpretation issues involving STR DNA profiles,
including:
¶ methods that take account of population substructure in DNA calculations;
¶ parallel work carried out by the US National Research Council;
¶ the move away from multiple independence testing in favour of experiments that demonstrate the robustness of casework procedures;
¶ the questionable practice of source attribution `with reasonable scientific certainty';
¶ the effect on the interpretation of profiles obtained under increasingly sensitive techniques, the LCN technique in particular;
¶ the use of DNA profiles as an intelligence tool;
¶ the interpretation of DNA mixtures.
¶
Experience of presenting DNA evidence within UK courts is also discussed. The
paper then summarises a generic interpretation framework based on the concept of
likelihood ratio within a hierarchy of propositions. Finally the use of Bayesian
networks to interpret DNA evidence is reviewed.
