Confidential informants (CIs) are critical assets in law enforcement, often providing invaluable information that can lead to significant breakthroughs in investigations. However, managing evidence obtained through confidential informants presents unique challenges, primarily due to the need for strict confidentiality and security. Evidence Management Systems (EMS) are designed to address these challenges by ensuring the secure handling, documentation, and utilization of evidence provided by CIs. This article explores how EMS handle evidence obtained through confidential informants, focusing on security measures, chain of custody, and operational efficiency.
