What is the purpose of a laser protractor kit in crime scene investigation?

The main purpose of a laser protractor kit in crime scene investigation is to calculate bullet trajectories. This specialized tool allows investigators to determine the path that a bullet took when fired, which is crucial for reconstructing the events that occurred during the crime. By accurately measuring angles and distances using the laser protractor, investigators can establish the position of the shooter relative to the crime scene, helping to answer important questions about the incident.

Understanding bullet trajectories can provide insights into the actions of individuals involved, the likely positions of victims and suspects, and the potential dynamics during the crime. This information can be critical in both the investigation and potential courtroom presentations.

In contrast, while measuring distances between objects and creating forensic models are important tasks in crime scene investigations, these typically rely on other tools and methods. Additionally, documenting the scene with photographs focuses on capturing visual evidence rather than the specific angles and trajectories offered by a laser protractor.
