Interesting. However, if defense sprays are used properly who cares? Only when abused like the UC Davis case is this an issue. Defense sprays are supposed to be seriously nasty stuff. My wife and daughters carry the nastiest stuff available. They will not abuse it, but I suppose an innocent could catch a whiff of it (most likely themselves). But that is a small potential hazard relative to the very real present hazard during an attack. Again, this is only concerning when authorities abuse their power, which is not a fault of the manufacturers of the sprays. If it were up to me cops like that would go to jail and we'd just shoot and kill rapists and thugs instead of spraying them. But I suppose I'm just an idealist.
