Blood Spatter Analysis Concepts

Detective Sergeant Norman explains blood spatter analysis, a technique used to understand crime scenes by examining blood patterns. The video covers setting up an experiment to observe different spatter types: straight up and down, medium, and fast. Each type provides clues about the events at the crime scene, such as the presence of a gunshot or blunt object. The video encourages viewers to analyze spatter patterns and draw conclusions.
