Also featured in an upcoming 'Dateline' special are Kris Jenner, Denise Brown, Fred Goldman, Alan Dershowitz and Kato Kaelin, among numerous others connected to the case. 
 
 Marcia Clark, the former Los Angeles County prosecutor who was the lead attorney on the O.J. Simpson murder case, says she blames herself for the controversial outcome of the case. 
 
 Sitting down for a Dateline NBC interview set to air Sunday, Clark shed some more light on the inner workings of the case which captivated the world more than two decades ago. 
 
 A preview of the pre-taped interview was released Tuesday; Clark sitting down with Josh Mankiewicz talks about not wanting Simpson to try on the gloves during the trial and how she felt when the jury foreman read "Not guilty." 
 
 "It was physically painful," Clark says of the verdict. "And I thought of Ron [Goldman] and Nicole [Brown], and I thought, 'This is wrong.'" 
 
 The double homicide has once again become a main topic of conversation following the recently launched FX series The People v. O.J. Simpson: American Crime Story. 
 
 So far, four episodes of the nine part series have aired. 
 
 The two-hour Dateline special will also feature interviews with Kris Jenner, Denise Brown, Fred Goldman, Alan Dershowitz and Kato Kaelin, among numerous others connected to the case. 
 
 In the preview for the special, Clark — played by Sarah Paulson in the FX series — says she blames herself for Simpson going free. 
 
 "But at the end of the day, we really ... there was no way to reach that jury," she tells Mankiewicz. "There was no way to make them believe. There really wasn't." 
 
 Clark also says she was against Simpson trying on the gloves, which police said the killer left behind, during the trial. That iconic moment, when the glove appeared to not fit, was a massive blow to the prosecution. 
 
 "That was not my call. That was not my call," she tells Mankiewicz. "I did not want him to try on the evidence gloves. I never did." 
 
 That idea came from co-counsel Christopher Darden, played by Sterling K. Brown in the FX series. Darden apologized to Clark for the massive blunder, she says. 
 
 "And I said, 'It’s okay," says Clark. "If that lost the case for us, we were never going to win anyway'.” ||||| O.J. Simpson’s first defense attorney, Robert Shapiro, has discussed new details from the “trial of the century” for the first time in 20 years. 
 
 Shapiro is portrayed by John Travolta in the hit FX series “The People v. O.J. Simpson: American Crime Story”, which has stoked interest in the trial. 
 
 The attorney stepped into the spotlight in an interview Tuesday with Fox News’ Megyn Kelly. 
 
 Shapiro, 73, said that a lot of what people think they know about the trial is wrong. 
 
 When asked whether the dream team of attorneys won the case or the prosecution lost it, he told her the verdict was “a combination of both.” 
 
 “The prosecution wedded themselves to one knife, one killer theory,” Shapiro said. “There is a strong possibility that more than one person was involved.” 
 
 Shapiro highlighted two major factors in the successful outcome for the defense. 
 
 He “outmaneuvered Marcia Clark by making her believe [he] wasn’t ready,” he said. “The judge asked, ‘Mr. Shapiro, what’s your position?’ ‘Your honor, we’re ready for trial.’ Looks at Marcia Clark and says, ‘Call your first witness.’ And you could see the blood come out of her face, and from that day on, I knew, there would be no conviction,” Shapiro recalled. 
 
 The other main factor, he said, was that the prosecution “did not understand the evidence.” 
 
 Shapiro admitted to trying on the glove before the trial and said he knew it would not fit Simpson. 
 
 He said he instructed Simpson, “‘I want you to walk as close to the jury as you can, hold up your hand like you’re holding the Olympic torch and pull and tug on that glove, because it will not fit.’ And clearly it didn’t.” 
 
 Shapiro also recalled what Simpson whispered to him directly after the verdict was read: “You had told me this would be the result from the beginning. You were right.”
– The former Los Angeles County prosecutor who failed to convict OJ Simpson of murder in 1995 says she would probably fail to convict now, for the same reason: Jurors who didn't care whether he was guilty or not. In an interview for an NBC Dateline special, Marcia Clark says some of the nine black jurors "came in for the purpose of payback" amid a similar climate of "racial mistrust" of the police as exists today. "They didn't care whether he was guilty or innocent," Clark says. "They were going to use this case for payback." There was plenty of evidence pointing to Simpson's guilt, but it "didn't wind up mattering because there was a fundamental large issue standing in the way of seeing the evidence," she says. "You had this enormous mistrust of everything LAPD, everything officer related." "There was no way to reach that jury. There was no way to make them believe. There really wasn't," Clark says, per the Hollywood Reporter, which notes that interest in the case has surged during the airing of the FX series The People v. OJ Simpson: American Crime Story. Clark says the infamous decision to have Simpson try on a glove found near the murder scene wasn't hers. She says co-counsel Christopher Darden came up with the idea and apologized after it backfired. She says she told him it was OK. "If that lost the case for us, we were never going to win anyway," she says. (A knife allegedly found nearly two decades ago on Simpson's former estate is now being tested by the LAPD.)
