THats a disgusting device that while the intended use could be awesome, the potential for abuse is horrible. Simply put, start castrating every rapist you find. If the punishment is so horrible, most people will learn not to do it. Don't make the women responsible for "being in the wrong place" or "not carrying a weapon". Beat the shit out of the dumb prick males that think this is an acceptable practice. If they wanted sex that bad, fine they made their choice, chop it off so they can never have it again. Or, as a first offense, brand it on their foreheads for everyone else to see, like the scarlett letter.
