One potential benefit of conducting a thorough investigation is:

A thorough investigation serves to substantiate a confession by ensuring that the evidence collected aligns with the statements made by the suspect. When investigators meticulously gather corroborating evidence—such as eyewitness accounts, forensic analysis, or digital records—they can validate a confession's authenticity. This process adds credibility to the confession and can significantly impact the case's outcome. Without a thorough investigation, a confession could be viewed with skepticism, particularly if it lacks supporting evidence or if there are inconsistencies in the details provided by the suspect. Therefore, the thoroughness of the investigation is crucial for reinforcing the legitimacy of confessions, helping to ensure that justice is served accurately and fairly.
