Regardless of what exactly the reason for dismissal of the original case, the fact is that got tried for the same crime twice (first as federal and then as a state crime). Unless new evidence has been unearthed, it feels like GS got themselves a way to get around the double jeopardy clause.It was only ever thrown out based on a technicality, basically under an obscure 1967 law that if something is written on paper it isn't "tangible".
PS. It comes from the same DA that charged the former head of the IMF with a rape he did not commit.
