Some recommended reading about the WM3 case:
Billy Sinclair: Why was Troy Davis executed and Damien Echols freed? I agree with Sinclair — both men were guilty, but neither should have been executed.
Pat Brown: Don’t Free the West Memphis Three. From two years ago but still a righteous, right-on rant.
Way of the Mammoth: untitled blog post, mostly about Roger Keith Coleman with oblique comparisons to the WM3.
