Hopefully he will remain that way but the story will probably die a death when the next thing comes along. All that's likely to happen is he'll disappear into obscurity until he dies ... unless something else incriminating comes up. If that happens, this'll all come flooding back to haunt him.
It would be nice to see him at the FBI's offices, but it's unlikely to happen.
Frankly, even hanging around with a convicted kiddie fidler rapist is enough to dump him from all royal duties, but his interview, or at least the bits I watched, was unconvincing at best. I don't believe a word, but my point of view simply doesn't matter, as is true of everyone elses unless something more concrete comes along to get him.
