Not exactly. The pink barbie nightgown is damning evidence against BR. Not only is is spattered with JBR blood, it has his tDNA all over it, including the front and back of the bottom hem area. I can see if it was perhaps in one or two of the spots tested, but it was on all four samples tested. JR and JAR tDNA is not on it.
tDNA is anything but "damning." Why is tDNA so important on the barbie night gown, but no at all important on the waistband? I know: because one supports BDI and the other supports IDI, which is a double standard.
Of course the night gown had his tDNA on it: it was an item kept in the same house that he was in, in the same play area that he frequented to boot. It means zero.
