Brucie -- I'm aware that the mishandling of evidence was the problem in the Milgaard and Marshall cases -- and as I said, I'm not familiar with the other one. But that's not the point I was making. If the technology we have today had been available in those two cases, there probably wouldn't have been convictions in the first place.
Amos -- I wish I had your faith. The fact that we can intellectually "come up with something better" and then, every time, revert to killing just may be a sign that the "something better" has no substance, but should be put in the category of "wishful thinking."
