This keeps coming up, and will not go away because the answers and explanations are not good enough. Their answers simply provide more questions. This is a lot like the Kennedy assassination. You have the "Oswald did it alone" crew. They think the conspiracy theory guys are all nuts. But they have tapes of Santo Trafficante and Sam Giancana who worked with the CIA saying "He's (Kennedy) going to be hit". They can't disprove it, so they ignore it. You have the cocktail waitress who Ruby introduced to Oswald 3 weeks before the assassination. They say she's "Lying". The 3 hobos, one who looks like E. Howard Hunt, and on and on. They have no explanation.
Fast forward to Barry Sorento, Barack Hussein Obama, or whoever the hell he calls himself now, and it's the exact same thing. Hussein can't prove a thing, so he won't say a thing. If your suspected of committing a crime, you don't talk to the cops. When almost 50% of the public thinks your a lying A-Hole of a "President", you don't talk to the press. Much like Kennedy, Hussein will go to his grave, and we won't know the answers. Bill T.
