"That is a really stupid statement. You are saying that the stock price is not manipulated because you can't "prove" it is manipulated. That is asinine."

Yes, it's so asinine that our entire court system is based off this simple principle. In the United States, when you accuse someone of a crime (stock manipulation is a crime), you must be able to prove it. I find it to be a very logical system that has worked for hundreds of years.
