Solid balls (glass breakers)

Solid plastic balls that are designed to shatter upon impact with a wall when shot from a paintball marker, yet possess enough force to potentially break a person's ribs or penetrate a car's window, would likely be considered a dangerous and potentially lethal weapon. Such use needs to be within reasonable doubt your life is in immediate danger. Using such projectiles for self-defense could have severe legal and ethical consequences, as they pose a significant risk to human life and property.
