It's never 'fair' brother, you know that. Common sense and doing the right thing always get put to the side at the 'expense' of others.
Now, on your unrelated comparison on a guy that was convicted and later exonerated via DNA. He was convicted by a Jury of his Peers. You know, guys like you and me. I don't like it and it sickens me that it happens up to and including being put to death. It's our system, not perfect, but it's ours. When injustices are found we try to correct them, not as well as we should for whatever reason, but we do try to make it right at some level. We could beat this whole issue into the ground and back and still not change a damn thing, so let's just agree 'fair' will never be realized.
