This is a grisley theory, but it would explain a lot. Karr was there, yet he was also at home. "A small foreign faction" -- forget the "foreign," it could be a ring of pedophiles who conspired for two to film the rape and murder of JonBenet. There were two unidentified foot prints in the wine cellar room. One rapes and kills while the other runs the video camera, to give the members a feeling as though they were participating. This would also explain Karr's initimate knowledge of the condition of the bruised body. You know those pedophiles most probably haunt the child beauty pageants undercover. They probably felt taunted and outraged and envious of the parents of pretty singing and dancing JonBenet. If Karr is privy to a "home movie," it was probably broadcast on a web private channel on the internet for a small, elite, silent, and highly paying pedophile club. Karr does not look capable of squashing a bug, let alone being brutal enough to do the real killing the way it was done. But he does look he is capable of being a stool pigeon. This pedophile ring would have had a possessive attitude toward JonBenet, as though they owned her. The media would totally freak on something like this, which might explain the great secrecy. If prosecutors have gotten wind that a film exists, they would have to make sure that film is totally secure from the media, and so that is why no one has brought this subject up or come even close to it. There's my theory. I hope I didn't repeat someone else's theory unknowingly. If so, I apologize; I've been away from the forum for awhile.
