I've had a couple days to digest this news, and my initial "gut check" feeling that he was the victim of sabotage has only strengthened. 
  There are really two separate issues here; one is the ITC's gross mishandling of the situation from the word go, and the other is the simple question of whether Dallas knowingly administered drugs or whether they came from a malicious source. I've watched his press release video twice and am utterly convinced that he didn't administer Tramodol. 
  Additionally, I feel that if he was intentionally breaking the rules and hoping that he wouldn't be caught, the easiest, smoothest way to duck the blame would have been to say something to the effect of "Oh, hey, I guess it turns out my wife/handlers DID give some pain meds to the dogs after they made it to Nome while I was sleeping. Oops." The ITC would have admonished him to be more careful in the future and this story would already be ending--as it is, it's just winding up.
