Legal investigators are responsible for providing factual evidence - as the fact finders, they are the foundation for the attorneys they work with daily. The attorney is responsible for forming and implementing the legal strategy and presenting it to the judge or jury. The legal investigator provides checks and balances to ensure that no evidence is being forced upon a theory, and that no theory is being forced upon the evidence. Practical Methods for Legal Investigations: Concepts and Protocols in Civil and Criminal Cases presents legal investigators with a step-by-step process that reveals how to methodically find and report evidence in every aspect of the investigative process.

Similar to the scientific principle of using research to prove or disprove a theory, the author's Investigative Protocol is designed to find the facts that prove or disprove criminal charges, civil allegations, or elements thereof. The book includes case studies that clearly detail how the process of the Investigative Protocol applies to every assignment of the case and to the case as a whole. Comprehensive and methodical, the system provides a map to the truth.
