DNA Identification Evidence in Criminal Prosecutions
In criminal cases, there have been challenges on sufficiency grounds and concerns over the use of forensic DNA evidence as the sole or primary proof of guilt. Uncorroborated DNA matching might not be enough to satisfy the burden of establishing guilt beyond a reasonable doubt. The reliability of forensic DNA testing results might be questioned for any number of reasons, e.g., laboratory error, cross-contamination, interpretive bias or fraud, etc. Ken Strutin’s essay provides an overview of nuclear DNA typing, a sampling of the kinds of discretionary decisions that analysts often confront when interpreting crime scene samples, and concludes with with remarks about current disputes in forensic DNA typing, and how recognition of its inherent subjectivity might inform and illuminate these debates.
