Apparently a medical technician in South Africa (where rape is epidemic) came up with this. My first thought was, "Oh ... HELL YES!" Then I got to thinking ... rapists are disgusting, worthless little jackholes to begin with. I'd be concerned this (as is) would increase the incident of homicide. So ... I'd have this injecting poison too - something fast acting that at least paralyzes the @#$! so the woman can get away.
