Which of the following describes bloodstains that are smaller than a freely falling drop?

Impact spatter refers to bloodstains that are created when blood is subjected to an external force, causing the blood to break apart and spread out as smaller droplets. This phenomenon typically occurs when blood is impacted by an object, like a blunt instrument or during a violent act. The smaller droplets generated from such impacts are a key characteristic of impact spatter and differ significantly from other types of bloodstains, such as drip stains, which are formed by the gravity-driven drop of blood.

Understanding bloodstain patterns is crucial in crime scene analysis, as these patterns can provide valuable information regarding the events that took place during a crime, including the type of force used and the movements of individuals involved. In contrast, other types of stains, like transfer or static stains, do not exhibit the same characteristics or implications as those found in impact spatter.
