Once again, police have some questions about Dominique Strauss-Kahn’s hotel habits. The former head of the International Monetary Fund was taken in for questioning regarding a prostitution ring after several call girls said they had sex with him at hotels in Paris and Washington. Strauss-Kahn says he didn’t know the women were prostitutes. “I challenge you to distinguish a naked prostitute from any other naked woman,” his lawyer Henri Leclerc said. In the same inquiry, French police have arrested eight men on suspicion of misusing corporate funds to pay for sex parties. It is legal to consort with prostitutes in France, but not to use corporate funds to do so.
