So how effective is pepper spray?
I would think that OC (Oleoresin Capsicum) spray, or pepper spray, is extremely effective after watching these videos. The problem is that when I watch the clip shown below, I begin to question trusting my life to this product.
Let's take a look at another person being sprayed. This individual is sober.
Not every situation rates the use of a firearm, and OC spray definitely has it's uses. There are times when deadly force isn't justified, and tasers or pepper spray are the best option.
IMO, the non lethal tools are a backup to your firearm, instead of being a substitute. Just don't over estimate their effectiveness, or become over confident because you have a little pink sprayer on your keychain.
This YouTube clip is a decent tutorial for those considering buying pepper spray.
