Of course I do not possess the ability to read minds, but considering that we are talking about people who had a loved one horrifically murdered, common sense would dictate that if any of them who felt the reasons they were given were at all insufficient, would be vocal about it.
I know CTers like to play the "silent masses" game in order to give the appearance of a consensus, but to imply that someone who had a loved one murdered would not publicly question an investigation into that murder they felt was inadequate is not only ridiculous, it's offensive.
The fact remains, you have a very small list of names out of a group of thousands of people. It's not even close to being a significant percentage, let alone a consensus.
So why do you feel that this very small minority's criticism of the 9/11 investigation is any more valid than the tacit approval given to it by the vast majority of others?
