‘Prints and marks: more ways to identify people and things’ outlines the examinations and evaluation of marks evidence (such as fingerprints and shoe marks). Marks evidence can often be 100% conclusive, making it a very useful tool. Fingerprints have been used in forensics for over 100 years, and rapid analysis of fingerprints is possible due to computerized databases. Shoe marks can link a particular shoe to a crime scene, but also provide information about the nature of the crime. Marks evidence has been criticized for being assessed categorically rather than through statistical means. It is also susceptible to confirmation bias.
