been sprayed twice by police officers. In the middle of a riot, me being the idiot trying to stop it before it started. Happened to be the same deputy,same type of incident, twice. Appolgised afterwards and we had a good laugh (he said that I was the "Biggest motherf--ker around, and you needed to go down first").
The first time it hurt. The second time I managed to fight through it and get out of the pit of angry individuals, get to relative safety, and promptly curse out the deputy. When he got off duty, we had a good laugh over a beer.
Concidentaly, I've been sprayed by non-law enforcement quality spray (I'm a security guard, got a bit of backsplash) and that stuff just doesn't really bother me all that much.
