Using your same standard of evidence, I’d have to say that it was probably just an accident that those planes flew into the Twin Towers. Ya know? Maybe the pilot fell asleep or something... I think you’re reading too much into those pesky details...
Are you really comparing believing a live event seen by tens of thousands and broadcast around the world with believing that BHO amended his vital records because Hawaii didn't tell you specifically that there's not a receipt for him having done so?
You're going to figure this out in your own time.
My larger concern is that you may make choices based on your presumptions that could be detrimental to you. Like when you posted some time back that you were considering not paying your taxes over this. But, perhaps I misunderstood.
Nevertheless you seem sincere in your investigation. And I'd rather decent folks not make bad choices based on false information.
