Okay, I'll go ahead and stir this pot. How close to 100% sure do you think is acceptable to be to convict someone if this is the punishment, and, are you comfortable with that one in a million person being you? I agree that a true violator of the above is not worth the resources to keep them alive, but consider that planted photographs, or a false rape claim by a crazy or vindictive person could see you being slowly skinned alive with vise grips over the course of 24 hours.
