"nonlethal"

Less lethal. The correct term is less lethal. There's no such thing as a nonlethal weapon. Pepper spray and tazers can be lethal under the right circumstances. "Rubber bullets" are rubber coated 25mm rounds that have been deemed sufficiently safe when bounced off of the pavement into a person's legs (and even then can cause serious injuries); they're not remotely safe when fired directly at a person's head, which is what cops often do with them.

Whenever you hear the word "nonlethal" used to describe a weapon, always remember it is only ever "less lethal."
