As a result of this analysis, the unit decided that one priority was to develop a tamper-resistant exhibit bag as a fundamental step toward improving drug exhibit security. A prototype bag was developed which aimed to minimize the time between actual seizure and first accountability by using a tell-tale seal to ensure the integrity of the exhibit. Design considerations associated with development of the Audit Bag included identification of container, chain of evidence, availability of containers to possible users, immediate sealing at point of seizure, and security. Several Australian states have successfully used the Audit Bag, demonstrated by improved evidence controls, less disputed evidence, and improved image of police professionalism.
