Less Than Lethal Defense
Non lethal weapons, also known as less lethal or less than lethal weapons can be used in situations where one can not carry a firearm or simply chooses not to for personal reasons. Less than lethal devices can be a pepper spray (Mace is a brand of pepper spray), electrical device (Stun gun, Taser) or a baton just to name a few.
While these options are especially popular with college students and elderly many people use this type of weapon for self defense. Joggers in particular like the idea of being able to carry something that is lite weight.
