In What is Traffic Accident Reconstruction And Cause Analysis?, traffic accident reconstruction expert witness Patrick Scott Moore writes:
Who are Reconstruction Specialists and how are they trained?
Reconstruction specialists are generally engineers, physicists, or law enforcement. Engineers and physicists are educated in the laws of physics, and therefore, are considered experts on objects in motion and the forces acting on those objects. Law enforcement is educated in the investigation of traffic accidents, as well as, physics as it applies to traffic accidents. Although it is generally true that engineers and physicists have a stronger background in physics, law enforcement generally has the stronger background in the identification, collection, and documentation of forensic evidence, as well as, courtroom testimony.
