I have to imagine theres more to this case than meets the eye.
Still the "repressed memories" and "dreaming of rape" and other silly witness testimony is hardly grounds to imprison someone for decades. Fortunately most of these cases seem to be from the 70's and 80's, its just that they're getting out now.
Even the best witness testimony without any hard evidence shouldn't be proof enough to convict, since you're talking about one person's word versus another, in most cases. At best, you're talking multiple witnesses.
