I got the pepper spray for late nights as a non-lethal method of defense for walking from the theater/restaraunt/etc. to my car in the dark. I keep in my hand in 'iffy' places, unitl I get in my car. I only take it with me when I'm out late at night. I use it instead of a gun because if I shoot and kill someone, I undoubtedly will have a lot of paperwork to fill out and questions to answer. I hope with this, I can just temporarily debilitate them and run for it.

Do a YouTube search on 'pepper spray' or 'Fox Labs' for some food for thought.
