When determining bullet trajectory, which factor is crucial?

In the analysis of bullet trajectory, the height of the shooter is indeed a crucial factor. The shooter's height influences the angle at which the bullet is fired in relation to the target. When reconstructing a shooting incident, understanding the shooter's position—especially their vertical alignment—helps forensic experts determine the likely path of the bullet.

For example, if a bullet strikes a target at a certain height and the evidence suggests that the shooter was significantly taller or shorter, it can impact the perceived trajectory. This understanding is essential when assessing scene dynamics and can guide investigators in determining the scenario of the shooting.

While factors such as the type of gunpowder, distance between the shooter and target, and bullet caliber are important in understanding the ballistic properties of the bullet and its potential impact, they do not directly inform the trajectory in the same foundational way that the shooter's height does. The trajectory analysis is primarily concerned with angles of fire, which are directly influenced by where the shooter was positioned vertically relative to the target.
