Which unit of measurement should an investigator develop an accurate sense for?

An investigator should develop an accurate sense for speed as it is crucial in various investigative scenarios, particularly those involving crime scenes, traffic incidents, or any situation where movement or time is a factor. Understanding speed helps to reconstruct events, assess the dynamics of an incident, and analyze how quickly certain actions took place. For instance, in a hit-and-run case, grasping the speed at which a vehicle was traveling can aid in estimates of timing and distance, which are key to piecing together the sequence of events and identifying potential witnesses or evidence.

Additionally, aspects of speed can also influence the determination of fault in accidents, as it can connect directly to the severity of impacts or incidents. Thus, having a keen awareness and ability to calculate and interpret speed accurately enables investigators to deliver more effective analyses and conclusions in their cases.
