What is one advantage of crime-scene sketches over photographs?

The correct option highlighting an advantage of crime-scene sketches over photographs is that they can include measurements.

Crime-scene sketches provide a detailed and accurate representation of the crime scene, often indicating locations of items, evidence, and important landmarks. By incorporating measurements within the sketch, investigators can provide a scale that helps convey the spatial relationships and distances between various elements of the scene. This critical information can be essential for investigations, as it allows law enforcement and forensics teams to understand the layout and dynamics of the scene in a manner that photographs alone cannot convey.

While photographs capture a moment in time, they do not inherently provide measurements or spatial context. Sketches can be tailored to include crucial details that may not be visible in photos, such as the placement of evidence relative to other objects and the overall context of the environment, which is vital for analysis and potential courtroom presentations. Thus, including measurements significantly enhances their utility in the investigation process.
