A professional investigator should first understand the scope, objectives, and legal boundaries

documentation can weaken the credibility of otherwise valuable evidence.

verified. What should the investigator do?
A. Include the information as confirmed evidence

B. To provide a clear, accurate, and objective record of findings
C. To summarize only evidence supporting the investigator’s opinion

investigation. What should the investigator do?
A. Automatically reject the witness statement
B. Ignore the physical evidence
C. Evaluate both sources and investigate the inconsistency further
D. Select the information that supports the initial theory

A. Reviewing documents related to a case
B. Conducting interviews with witnesses

questioning techniques
