I have been in CS gas chambers, Had cs used on us in training etc. But once. I was working an off duty armed security job about ten years ago. we we were gaurding the transit system, buses, light rail, etc. I was removing a drunk off the 66 bus in san Jose. He got a little wild. The guard with me sprayed us both. My eyes clampted shut, it burned. I was annoyed with this person. BUt it works. I own a personel taser. I keep itin the car.
