Self defense weapons can be divided into two categories: Lethal and less than or non-lethal. Not everyone can or should carry a lethal form of self defense, but there are non lethal alternatives available for everyone. So who should keep a self defense product? Should you?
The purpose of non lethal self defense products is to disable or distract an attacker long enough for the potential victim to escape from a threatening situation or to get help. They are not designed to permanently injure another being.
