I can tell you from experience that getting sprayed with oc is not a pleasant experience. I was a summer cop years ago and we were sprayed directly in the face for training purposes. I was on my hands and knees for at least 45 min. with my face in a bucket of soap and water to wash it off. It's like bobbing for french fries still in the fryer! <img src="/images/graemlins/shocked.gif" alt="" />I personally try hard not to get into fights in the first place. Survival is about getting rescued or to self rescue. I would consider that using oc to delay someone who wants to cause me bodily harm would be a valid survival tactic. I have no experience with Tasers.
