Robert Durst spent the night before his arrest wandering around New Orleans' French Quarter with a loaded .38-caliber revolver in his pocket, claims a nightclub doorman who accosted him. The millionaire real-estate heir and murder defendant was arrested on Saturday at the JW Marriott hotel, where cops found the gun and marijuana stashed in his room. John Phillips, 32, a doorman at the Mahogany Jazz Hall Burlesque and Absinthe House said Durst approached him just before midnight on Friday. Robert Durst spent the night before his arrest wandering around New Orleans' French Quarter with his loaded .38-caliber revolver in his pocket, claims a nightclub doorman . 'I asked him to come into the club, but he said in a female-ish soft voice, "I would like to come in, but I can't right now,"' Phillips told the New York Post. Durst, 71, then pulled open his brown-tweed suit jacket to reveal the butt of the gun in a belt holster, Phillips said. 'I thought to myself, I hope this old guy with a gun doesn't do anything stupid.' Phillips said that 'the whole exchange took less than a minute' outside the club and Durst 'just stumbled a little as he walked down the block.' 'I just thought he was an old man who was a little bit off. I kept thinking this old guy is on too much prescription medication.' Durst, 71, was arrested on the eve of Sunday's final episode of 'The Jinx: The Life And Deaths Of Robert Durst,' and he agreed on Monday to face trial for the murder of Susan Berman, who had vouched for him in public after his wife vanished. The final episode ended with the whispered words of Durst recorded in an unguarded moment in a bathroom. 'There it is. You're caught!' Durst whispered before the sound of water running can be heard. 'What the hell did I do? Killed them all, of course.' John Phillips, 32, a doorman at the Mahogany Jazz Hall Burlesque and Absinthe House said Durst revealed to him that he was carrying a weapon . The whispered words of Durst recorded in an unguarded moment in a bathroom could come back to haunt him - or help him - as he faces a murder charge . Now those words could come back to haunt him — or help him — as he faces his murder charge. A possible move by prosecutors to introduce the incriminating material from a six-part documentary on his strange life and connection to three killings could backfire as interview footage did in the Michael Jackson molestation trial and the Robert Blake murder case. In both cases, the defense was allowed under the 'doctrine of completeness' to provide segments of interviews that presented their clients favorably without subjecting them to tough cross-examination. 'I submit that Blake didn't have to testify and Michael Jackson didn't have to testify because the prosecution foolishly wanted to introduce portions of their interviews,' said attorney Thomas Mesereau Jr., who represented both men. 'They just got greedy. They were mesmerized by portions they thought could help them.' In the Jackson case, the defense used unaired footage to counter damage done by Living With Michael Jackson, a damning documentary in which Jackson held hands with his accuser and spoke of letting children into his bed. 'I'd slit my wrists before I'd hurt a child,' Jackson said in one outtake shown by the defense, according to Mesereau, who won the performer's acquittal 10 years ago. Michael Jackson's lead defense attorney Thomas Mesereau Jr. said the so-called incriminating material from the Durst documentary could backfire as interview footage did in the Jackson molestation trial in 2005 . In the Durst case, prosecutors could seek to play portions from The Jinx that concluded with the eccentric millionaire off camera talking to himself in a bathroom with his wireless microphone still live. He has been charged in Los Angeles with first-degree murder in the 2000 killing Susan Berman, the daughter a mobster and a close friend who acted as his spokeswoman after his wife disappeared in New York in 1982. Durst, 71, who is estranged from a family that has a real estate empire worth an estimated $4 billion, has long denied killing Berman and Kathleen Durst, who was declared dead even though her body was never found. Investigators had reopened that case and planned to speak with Berman when she was shot once in the back of her head at her home near Beverly Hills. After the killing, Durst disguised himself as a mute woman and moved into a cheap Galveston, Texas, boarding house where he killed an elderly neighbor in 2001. He claimed self-defense and was acquitted of murder but convicted of unlawfully disposing of the man's body, which was found chopped up and floating in Galveston Bay. Actor Robert Blake, left, talks with his attorney, M. Gerald Schwartzbach: Prosecutors sought to introduce a portion of a jailhouse interview of the actor discussing his family with Barbara Walters because it contradicted other evidence . While legal experts said Durst's remarks off-camera and to filmmakers during the production will most likely be admissible, prosecutors will have to decide if they outweigh the possibility that the defense would play other portions of interviews showing him denying any killing. 'I would see this moment of unguarded truth as worth a lot of those denials,' said George Fisher, a former prosecutor and professor at Stanford Law School. 'The flat out meaning of the statement is very clear on its face.' In the case of Blake, prosecutors sought to introduce a portion of a jailhouse interview of the actor discussing his family with Barbara Walters because it contradicted other evidence. The defense then successfully pushed to bring in the rest of the interview. 'It did a great deal both to humanize him and so he wasn't just seen as a celebrity,' said M. Gerald Schwartzbach, who won Blake's acquittal on a murder charge involving the killing of his wife. 'There was an image projected that a lot of people had about Robert as a difficult person. In this video, he came across as a very sympathetic person.' Prosecutors are not commenting on the Berman case while Durst is still held in Louisiana, where he also faces firearms charges.
