I don't follow the line of reasoning here...since Vitor's case has more questions than sonnen's, it somehow equates to people giving him "a pass?" Simply indicating that there are questions that will never get satisfactory answers somehow equates to a "get out of jail card?"
I don't know anyone who hasn't said it's anything less than probable that Vitor was juicing. But there are questions, and they can't be ignored. My only concern has been with people who assume they know more than than anyone can know, and who ignore the questions because they're too inconvenient to fit in with what they believe happened, or when they state this belief as fact.
The kid who got banned brought that on himself. If he'd made the same statements about sonnen, he would have been warned; if he continued to make them after the warning he would have been banned as well. It's the internet, it means nothing. I'm exceptionally confident his life will go on without a hitch.
