The prosecutor can make whatever claims he wants in an extradition hearing, but until the case actually sees the inside of a US courtroom I do not think anyone really knows how these are going to hold up. In this case you are running into a situation where the US prosecutor may be (significantly) over-playing his hand, but I am not sure how much latitude this court has to call bullshit on the claims being made by the US prosecutor.
