True or False: A rough sketch should be made after leaving the scene of a crime.

The assertion is false because a rough sketch is an essential part of the crime scene investigation process and should be created while still present at the crime scene. This is crucial for capturing the accurate layout, spatial relationships, and significant details of the scene before any alterations or evidence disturbance occurs. By making the sketch on-site, investigators can ensure it reflects the real conditions and evidence as they were initially discovered, which is vital for both the investigative process and any future legal proceedings.

Creating a rough sketch after leaving the crime scene could lead to inaccuracies or omissions, as a person's memory may fade or details could be overlooked. Additionally, the immediacy of recording information at the scene helps establish a clearer connection to the evidence gathered. It is a fundamental practice in forensic investigation to document the scene while still on-site to uphold the integrity and reliability of the investigation.
