ABSTRACT

Forensic Technology: Algorithms Strengthen Forensic Analysis, but Several Factors Can Affect Outcomes   [open pdf - 3MB]

From the Highlights: "For more than a century, law enforcement agencies have examined physical evidence to help identify persons of interest, solve cold cases, and find missing or exploited people. Forensic experts are now also using algorithms to help assess evidence collected in a criminal investigation, potentially improving the speed and objectivity of their investigations. GAO [Government Accountability Office] was asked to conduct a technology assessment on the use of forensic algorithms in law enforcement. In a prior report (GAO-20-479SP [hyperlink]), GAO described algorithms used by federal law enforcement agencies and how they work. This report discusses (1) the key performance metrics for assessing latent print, facial recognition, and probabilistic genotyping algorithms; (2) the strengths of these algorithms compared to related forensic methods; (3) challenges affecting their use; and (4) policy options that may help address these challenges."
