Yes, but one cannot ever be too sure---------which is the sad part, but one fact is that "accidental" executions are almost obolsete, and the ones many are rerfering too are executions made durring the past 20 years for people that have been sentenced to death in the 70's and Dna testing has proved them inoccent. Now, if your sentenced to death, its almost flawless evidence that you did it, Dna or not.
