As I posted in the 911 thread that seems to have gotten erased, when it comes to theories, it is very very difficult, often impossible, to ever conclusively disprove, beyond any doubt, that something happened.
Can you prove, with 100% certainty, that the KGB didn't kill Kennedy? Can you prove, with 100% certainty, that Castro didn't kill Kennedy? Can you, for that matter, prove that Kennedy wasn't shot by the ghost of Teddy Roosevelt? As absurd as any of those propositions are, you simply cannot prove any of this. You can, however, with just a few small pieces of conclusive evidence, prove that something did happen, therefore the burden of proof always lies with the prosecution, and not the other way around. The defense merely has to block or discredit the prosecution until the enough doubt is raised. Hence, the standards of proof, even in the biggest criminal cases, never go beyond 'a reasonable doubt', where the jury needs to be more or less 90-95% sure that something did happen as the prosecution said it did. Anything beyond is simply too much to ask.
This list is likely a load of crapola. However, there is not a single fact presented in that Snopes report that 'proves' that anything. Yes, it makes the conspiracy sound idiotic, which would be enough in court, but, for the conspiracy theorists (which I am usually not), it's enough if there's still a .0001% probability that it COULD have happened. Since there is always that .0001%, there will always be the

For the record, I'm not a big believer of this list. I'm not a Clinton fan, but, at the same time, not a big Clinton hater either. I thought the list would be fun. I'm not yet sure if it was.
Oy yeah, and here's another.... Prove that I am NOT Nash.
