Here's the bottom line though: you can't credibly give me the name of so much as one single person that we know was excecuted in America for a crime that he didn't commit.
No and I would not dare do so because I am not in position to investigate and carry through with that statement. I certainly hope you are correct but the sciences used in all phases of life are not fool proof and with the odds I dare say quite a few people have be executed for crimes they did not commit.A lot of law enforcement techniques have changed in my lifetime and I have personally observed things peddled to the law enforcement community that I do not or did not trust and a lot of law enforcement officers could back that up. You will always have human error and do not think for one minute the system is infallible.
