- Projectiles of >100Â g, shot from a sling, can cause injury at a distance of >100Â m.
- Asymmetrically shaped projectiles weighing >100Â g are the most dangerous.
- Police must wear full riot gear and keep a distance of >60Â m from danger source.
Herein, we analyze the energy parameters of stones of various weights and shapes shot from a sling and based on this data evaluate its traumatic potential. Four police officers proficient in the use of a sling participated in the trials. The following projectile types, shot using an overhead technique at a target 100Â m away were: round steel balls of different sizes and weights (24Â mm, 57Â g; 32Â mm, 135Â g; 38Â mm, 227Â g); different shaped stones weighing 100-150Â g and 150-200Â g and a golf ball (47Â g). Our data indicated that projectiles shot from unconventional weapons such as a sling, have serious traumatic potential for unprotected individuals and can cause blunt trauma of moderate to critical severity such as fractures of the trunk, limb, and facial skull bone, depending on the weight and shape of the projectile and the distance from the source of danger. Asymmetrically shaped projectiles weighing more than 100Â g were the most dangerous. Projectiles weighing more than 100Â g can cause bone fractures of the trunk and limbs at distances of up to 60Â m from the target and may cause serious head injuries to an unprotected person (Abbreviated Injury Scale 4-5) at distances up to 200Â m from the target. Due to the traumatic potential of projectiles shot from a sling, the police must wear full riot gear and keep at a distance of at least 60Â m from the source of danger in order to avoid serious injury. Furthermore, given the potential for serious head injuries, wearing a helmet with a visor is mandatory at distances up to 200Â m from the source of danger.
