Then again, playing devil's advocate, that's only one side of the story. Just as in the case of Rubin "Hurricane" Carter, there is always an equal chance that those proclaiming innocence can be just as full of shit as those demanding (misguided) justice. Just because one is "different" does not make one guilty, but it does not make one innocent either.
We heard the same "sloppy police work" claims during the OJ trial, and probably every trial that ever was could claim the same. I'm not saying that the Memphis three are guilty, but I'd prefer a more comprehensive and unbiased analysis.
Rubin Carter, by the way, is about as innocent as OJ
