Fort Hood and Changing Stories

I have been watching and listening to many of the original reports and the slow change into what we have now as the "official" story.  Listen to this guy who is on the military base and lists as one of the knowns that there was more than one shooter.  In fact, this was the story until about 8 hrs after the event.  Another part of the story we thought we knew until that time was that one of the suspects was dead.  Oh wait, actually he is alive.  Oops.  Come on, I really hope people are not so naive to believe some of these changes as honest mistakes and intense investigation for the truth.  We will never know the truth, unfortunately, but we know we are not getting anything close to it as of now.
