Okay, boys and girls, I'm going to break it down for you. Pepper spray, or oleoresin capsicum spray, is not the be-all and end-all. I was a police academy pepper spray instructor/trainer, meaning I trained recruits and other instructors.
Pepper spray will not work on all people. Let me give you an example. You are the father of a newborn. You are carrying your newborn in your arms, and someone comes up to you with the intent of stealing your baby. They spray you. Grab your baby. What are you going to do? You fight back and get your baby back at all costs.
Pepper spray WILL NOT IMMEDIATELY incapacitate you.
Having this in mind, along with other tactics and weapons, will help you know what to do.
