I also love me a great conspiracy theory, they are fun *but cant be dangerous*. I actually watch and have watched a ton of them, they are all over the internet. After I watch a particularly persuasive one, i usually do myself a favor and fact check it.
First i use logic, it almost always makes me chuckle at the theory in question. In this particular one ALL the "devastating" evidence is through themselves *cold case posse* and a lot they "cant release" so you have to just trust them completely, already that sounds peculiar. They also associate with the tea party, which means they may have a heavy bias towards Obama, which is a pretty heavy strike against them. Another good point is that this has been looked at a lot *and that is being modest*, you would think the best have already verified that it is legitimate. It is a pretty big deal after all.
Finally I go through and find people who have debunked this *if its popular enough you will find plenty*. This stops me from foolishly believing a conspiracy theory and ranting to everyone about it. I would post what i found but i can't post links until i hit a post count of 10 =p
