The New York Times reported Thursday that Tristane Banon, the French journalist who has accused disgraced ex-IMF chief Dominique Strauss-Kahn of attempting to rape her back in 2003, was questioned jointly with DSK at a Paris police station for over two hours. This, of course, is on the heels of the high-profile rape allegations against DSK made by a hotel maid in the U.S. According to the Times, "The joint questioning, a normal part of sexual assault cases in France, could represent a last legal step for prosecutors before either bringing formal charges, or dropping the case." How does this joint questioning work?
