Surveillance video from the New York hotel where former IMF chief Dominique Strauss-Kahn was accused of sexual assault proves that the hotel maid was telling the truth, according to her lawyers.

So do the hotel owners Accor, who have again reacted angrily over other images apparently showing two employees celebrating - insisting the scene is irrelevant.
