I'm not sure if I heard it right and it might just be media "spin" since they have been excluded thanks to the wisdom of a judge who has already put a gag order on this.
Like you, I feel as though we just have to wait for more official information and we certainly can't simply trust "the news". But if charges aren't filed against Karr, I will want to know what is the official reason why. If there's truly exculpatory facts, such as they know he couldn't possibly have been there, I won't waste a second crying about it. The only thing that would bother me is, still no justice for JonBenet.
It was probably media spin. Theya re saying all sorts of stuff like that. Believe me, if the media had actually heard for sure that charges may not be filed it would be bigger news, not a guess by a TV journalist.
