Pepper spray has it's uses. I use Freeze +P also.
When buying o/c, make sure you get one that is delivered in a liquid stream, not a spray. Sprays will surely get you!
The two times I have had to hold someone at gunpoint, they just ran or drove away-knowing I could not shoot them.
Had I had o/c with me, I could have sprayed face, then crotch.
All I would have had to tell the responding officers would have been, "Look for the screaming, crying guy with no pants on!"
