Which factor can negatively influence the accuracy of an investigator's report?

The time lag between observation and reporting is a critical factor that can negatively influence the accuracy of an investigator's report. When there is a delay in reporting, the investigator may forget crucial details or misinterpret events that were observed. Memories can fade, and the context of the situation can become distorted over time, leading to inaccuracies in the report. This is particularly relevant in investigative work, where precise details are essential for forming a clear and factual account of an incident. If observations are recorded immediately, the information tends to be more reliable, preserving the investigator's observations in their original context. Thus, minimizing the time gap between seeing an event and documenting it helps to ensure that the report accurately reflects what transpired.
