What if only those who admitted to such crimes were killed. Such crimes including 1st degree murder, rape, child molestation and treason. Then other than those such cases I think it would require some form of evidence to put the suspect at the scene such as DNA or photos. If it is a "clear" cut then it should theoretically never fail. But I think 1:1000 would still be acceptable. It takes a lot in this day and age to be convicted of crimes of those degrees with that certainty and still be innocent.
