I exercise my US Constitutional right to concealed carry a firearm and I diligently train in the civil right of self-defense because I’m pro-life and pro-social justice, since malicious and violent criminals and terrorists don’t have the right to steal a person’s life, liberty, and happiness.

Why Use and How to Choose Pepper Spray

If you carry a gun for self-defense, you should also carry pepper spray.* Even if you don’t carry a gun, you should carry pepper spray, also known as oleoresin capsicum (“OC”).

Using a firearm for self-defense is always the very last option in a lethal attack situation. But you shouldn’t rely solely on a gun as your only means of self-defense. FBI/DOJ crime statistics tell us we’re 5 times more likely to be faced with a non-deadly threat, against which only non-deadly defensive force is legally appropriate, than we are a deadly threat.

Under what circumstances is the use of pepper spray as a defensive tool lawful and advisable? What conditions have to be met before you can use pepper spray in self-defense? Pepper spray is a non-deadly form of self-defense and can be used to stop any reasonably perceived threat of non-deadly harm, which means almost any degree of harm. So long as you use it defensively and not offensively, generally speaking you should be within your rights.

In the following video, Chris Baker of Lucky Gunner says, “OC gives you a force option that’s somewhere between harsh language and shooting somebody. We all know that statistically, we are very unlikely to end up in a situation where we need to use our firearm to defend our life. Much more common are situations that call for some kind of intervention that’s less than deadly force. Maybe someone is behaving in a threatening way, but they don’t have a weapon and they have not done anything yet that would warrant using deadly force. That might be a good time to deploy some OC.

15 Truths About Defensive Gun Use

While Gun Murders Are Unlawful, Gun Homicides Are Not Necessarily Unlawful.
Don’t be fooled into misreading homicide statistics reported in the media. Not all homicides are social ills. Some homicides are justified lawful killings in self-defense or defense of others. For example, the intended rape victim who manages to kill her rapist in the act has committed a homicide. Would we prefer that she had been raped? The potential homicide victim who kills their attacker, rather than get killed themselves, has committed a homicide: lawful self-defense. Would we prefer that the victim of the attack have been killed?

According to attorney Andrew Branca, author of The Law of Self Defense, “a homicide (the killing of one person by another) can be

  • unlawful and intentional—what is traditionally referred to as murder—or
  • unlawful and unintentional—what is traditionally referred to as manslaughter or criminally reckless homicide—or
  • lawful and intentional—usually self-defense or defense of others—or
  • lawful and unintentional—accident or misadventure.”

Don’t be deceived when people talk in generalities that the number of gun deaths or homicides have increased and therefore more laws are needed to infringe on the civil right to keep and bear arms. Maybe the homicides being reported are of criminal aggressors attempting to murder and maim and rape innocent people, and they were killed by their victims or by people stepping up to defend those victims.

A murder is a homicide that’s unlawful; a self-defense killing is a homicide that’s lawful.
