People choose to carry non-lethal self defense weapons or keep them in their homes for a number of reasons. The most common one involves the safety and well-being of others. If someone is trying to do you harm, of course, your top priority is going to be keeping yourself safe. While not in use, however, weapons like guns can pose serious risks to others. Parents are especially concerned about keeping certain weapons in the home. The right non-lethal weapon will be every bit as effective as a lethal weapon, but it won’t pose the risk of serious bodily injury or death.
