Well, there's your first problem.
Put it this way, we've had years of 'truthers' coming to this forum and exclaiming that they cannot see how we can't accept that 9-11 was an inside jobby job and how can we possibly call ourselves skeptics when it's all soooooooo obvious.
But the truth is that the defendants were found guilty. Their innocence is not obvious.
The same can be said about their guilt.
