When Detective Stabler is on the witness stand testifying in the "flasher" case the defendants lawyer was trying to make Stabler out to be a prude who didn't approve of "non-traditional" sexual behavior. Which leads him to ask Stabler if he is "the Ken Starr of the NYPD." Ken Starr is an American lawyer who served as a U.S. Circuit Court judge and also a federal U.S. Appellate Court judge and also served as the U.S. Solicitor General during the Bush (senior) administration. He is best known for leading the independent investigation into the misconduct of President Bill Clinton, specifically the president committing perjury when he lied under oath about being in a sexual relationship with White House intern Monica Lewinsky. He is the author of the infamous and controversial Starr Report, which detailed his investigation into the presidents alleged sexual harassment of interns in the White House. The report's accuracy and validity has been called into question because it seemed to focus more on the type of sexual acts the President did with Ms. Lewinsky than on any improper conduct he had with other interns in the White House. Many people accused Starr of using the investigation and his report to further his own political agenda, specifically his belief that sex should be just for procreation and nothing else. He even leaked lurid sexual details about the President and Ms. Lewinsky to the media while he was still compiling the report, details that were later proven to be untrue. Starr was charged for violating legal ethics by presenting information irrelevant to an investigation as evidence of legal wrongdoing by the President. None of the investigations into the President's conduct revealed any additional legal wrongdoing, other than the President's perjury. Even Starr's report didn't uncover any unlawful activity.
