The U.S. government cares a lot more about foreign dignitaries, than U.S. citizens. According to New York state law, only a judge can decide if diplomatic immunity applies to DSK.
The Judge in this case has already convened a Grand Jury, which handed up a seven count indictment.
DSK was arraigned in Criminal Court on June 6.
This is not a case before the US government. It is a criminal case, and NYS law trumps any interference by the Feds, who have no jurisdiction in criminal matters in NY.
DSK has not made a legal claim of Diplomatic Immunity, and the IMF has stated clearly he was in NY on personal , not IMF business.
Cynical, aren’t you?
