The problem in Assange's case is that it is very hard to separate the charges being brought against him from the fact that he did something that is almost certainly legal but which the U.S. government would like very much to punish him for. The fact of the matter is that you can make someone's life miserable by bringing trumped-up charges against them, and this is especially easy to do if you're a powerful person. And if you're powerful enough then you can most likely do this with impunity. The possibility that this is happening to Assange needs to be taken very seriously.

So no, there is no overt indication that Assange is being treated any differently from any other accused rapist. But anyone who is content to leave it at that has blinders on.
