@PastorM - I now think that is just a screen name (PastorM) - for that jaw for a tooth payback system is not so Christian
I should point out, while making this arguement, that I do know someone close, who was raped when she was barely 11 years old - I have a daughter and would definitely sever both heads off a rapist if i caught one...
But, here we have a device that is widely available and perhaps likely even to be abused - perhaps rather than have the "biting" effect - why not have a small dose of tranquilizer...such that the rapist suffers instant flaccidity (nothing like killing his ego and the moment)....and have such doses remain in the system so for a repeat offender who encounters this tranquilizer - that the second dose has a permanent effect? That would be justice out there - no need for castration/imprisonment etc - it would be passive disarmament...
