I can't argue with that, SkyDancer. I keep a can here for wasps, and it should work fine on feral humans, temporarily. I even recommend it for gun-shy friends or for places where you can't have pepper spray.
My problem with a spray is that it is unlikely to make a real change in the bad guy, and just teaches him to be more careful the next time. I'm not interested in training the vermin.
Well at least you’d be able to get away. Then too, it might have taught them something like maybe the next person might do the same thing, or, have a gun.
