Executive Summary
DI-103 provides a disciplined method for testing anonymous complaints and confidential-source allegations through basis of knowledge, motive, and corroboration.
An accusation can be specific, confidential, and confidently repeated—and still rest on an untested source.
DI-103 explains how defense investigators preserve the original complaint, identify the source’s apparent basis of knowledge, test corroboration, and distinguish public or easily obtained details from information that genuinely supports reliability.
The publication also examines prior accuracy, motive, bias, benefit, pressure, opportunity to observe, routing history, and the timing of government corroboration. It does not equate anonymity with deception or confidentiality with truth.
The goal is to turn a label such as “confidential source” into a precise evidence assessment: what was verified, what was contradicted, what remains unknown, and what government action occurred before or after corroboration.
Who Should Read This Publication?
Military Defense Counsel
Evaluate how a tip affected probable cause, investigative decisions, discovery, confrontation issues, and litigation strategy while protecting lawful source restrictions.
Defense Investigators
Preserve the original allegation, reconstruct its routing, test basis of knowledge and corroboration, and report limitations without trying to expose a protected source improperly.
Service Members
Understand why an anonymous complaint may begin an inquiry but does not eliminate the need for independent evidence, accurate timelines, and careful defense investigation.
Experts
Address narrow digital, linguistic, behavioral, or data questions that can test a source assertion without offering unsupported opinions about overall credibility.
Families
Preserve relevant communications, calendars, photographs, and records, but avoid public speculation, retaliation, or attempts to identify or contact an anonymous source.
