It's difficult to figure out just what is wrong with the death row inmate. I love Sarsgaard, however, that part of the show annoys me and I just tune it out. The way they are portraying the death row inmate is so unrealistic, that I can't tolerate it. I've watched lots of documentaries on prisons and death row inmates and they aren't housed like that guy is. It's ridiculous. I'll have to just ignore it and follow the rest of the show.
Maybe he is guilty and the whole thing about the new murders is something totally different or it's like Archie ComicFan says and is a copy cat that he paid for. I just find myself not caring what happens to him though.
