I am a different combination altogether. I don't believe the accusers' stories as they stand (and I am far from a fool).
I believe that BSK's investigation in 2005 was exhaustive and nothing further will come out that corroborates the story, nor will there be other alleged victims. No charges will be filed against Bernie (though,unfortunately, he can never be truly "cleared;" even if D & L recant their stories, some will claim they were bought off, intimidated, etc.), but he will retire anyway.
On the other hand, as the saying goes, if the facts change, then so too may my opinion. If I am completely wrong and it turns out that something dreadful did, in fact, happen and BSK somehow missed it, I still think that JB will survive, more or less. He will be retiring in a few years anyway. If the worst happens, he will leave in 2 or 3 years rather than 3 to 5.
