Executive Summary
An OSI, CID, or NCIS Report of Investigation may present allegations, summaries, investigative steps, and conclusions in a single narrative.
That narrative should not automatically be treated as proof. Referenced attachments may be missing, investigative leads may be incomplete, technical findings may be overstated, and conclusions may not be fully supported by the underlying evidence.
This Authority Publication provides a practical framework for reviewing a military investigative report line by line.
It explains how to trace important statements back to their original sources, identify omissions and unsupported conclusions, document unresolved questions, and distinguish confirmed facts from allegations, interpretations, and assumptions.
Who Should Read This Publication?
- Military defense attorneys reviewing OSI, CID, or NCIS investigative files
- Defense investigators conducting an independent review of a government investigation
- Paralegals and case-team members organizing reports, attachments, recordings, and discovery
- Experts and consultants evaluating technical findings or evidentiary conclusions.

About Michael West
The investigative guidance presented throughout these Authority Publications is based upon decades of professional experience conducting military, federal, criminal, civil, and private investigations. The principles discussed in these publications are drawn from real investigative work involving complex cases, witness development, evidence analysis, and factual case preparation.
Michael West has served as a Special Agent with the United States Air Force Office of Special Investigations (AFOSI) and the Department of Defense Inspector General, conducted federal background investigations, and spent decades working as a licensed private investigator supporting attorneys, businesses, service members, and private clients.
