...footprints from the crime scene showed that the culprit’s trainers had damage that did not match the trainers later recovered from the accused. However, the expert assigned this evidence a ‘likelihood ratio’ of 1 (meaning that the evidence was neither exculpatory nor inculpatory). Logically, the value should have been less than 1 (because it was exculpatory). The...
