Well, I think it is important to the timeline, and I think that the order of who called, and who/what each had to say on the call will be of importance as well. I'm most intrigued that GGP placed a call, and where that call lies in the order of calls could be important as well. But I also agree with TheTruthWillOut that the most significance it has at this point is that Klein disclosed the information, then refused to clarify what is obviously not correct using the excuse that "it goes to timeline". Then why disclose the information in the first place? Personally I don't care much for Klein. I think he is a raging egomaniac that has used this case for publicity and to feed his ego. He is extremely unprofessional imo. It is insulting that he would put out contradictory information to the public, then refuse to clarify what was probably HIS mistake. He constantly makes derogatory remarks about the people following this case, clearly he thinks we are all beneath him and should be grateful that he throws us a morsel every once in while, regardless of whether it is accurate information or not, we should be grateful anyways.
What exactly has he done for this case, besides ride the coattails of LE and FBI? And gain publicity for himself? And feed his ego? I'd like to know what progress he has really made that LE and FBI weren't on to already. Sorry for going a bit OT there...
IMO.
