That's exactly it.
From the website of Barry Scheck himself --
A DNA forensics lab finds that 60% of the post-conviction tests it performs actually confirm guilt and yet all these leftist journalists, academics, and clergy are "surprised" that LaGuer turns out to be a typical case. This has got to tell us how little they know of the subject they are so passionate about. After LaGuer had spent 8 hours raping, robbing and brutally beating his 59-year-old next-door neighbor, one of the things she told police was that she had put scratches in his back with her fingernails during the crime. When LaGuer was picked up, he had fresh scratches on his back consistent with this report. He told police that he had gotten them from a nail in a bar he was at. Then he later changed his story and said he had gotten them from a wooden bench a month before the attack occured. When asked why his wounds were still fresh, he said he picked at the scabs a lot. This man is nowhere near as "intelligent" as his defenders make him out to be. The crowning irony is that his refusal to admit his guilt continues to make him ineligible for parole 20 years after his offense. To get out of prison, he will have to admit that he's been a liar all along and has abused the judicial process -- which in turn looks bad to the parole board. And when supporters like Prof Leslie Epstein and Nation of Islam "minister" Don Muhammed continue to encourage LaGuer in his denials, they are actually helping to ensure that he will serve out his entire life sentence. If he'd simply admitted the obvious, he would probably already have been released. Funny, how these things work out, isn't it? But none of this will stop fools like William Styron, John Silber, Noam Chomsky, Barbara Walters and this whole liberal cast of thousands from repeating their performance over and over and over and over...
