Sociopaths don't have a demeanor

William Rashbaum and John Eligon have an article in The New York Times about the upcoming trial of Dominique Strauss-Kahn:

Dominique Strauss-Kahn was running late. A street fair had shut down a stretch of Avenue of the Americas between his Midtown hotel and the restaurant where he was due for lunch. Stuck in traffic, he called his daughter, Camille, from a taxi to tell her he was on his way; she should go ahead and order for him, he said. Once he arrived, they had fish, and shared a chilled bottle of white wine.
The lunch that Saturday afternoon, in a wood-paneled seafood restaurant eight blocks from his hotel, began less than an hour after what prosecutors have charged was his sexual attack on a 32-year-old Guinean housekeeper who came to clean his suite. The account of the meal— its timing, its description, and the events that immediately preceded it— is based on interviews with people briefed on an investigation undertaken on behalf of Mr. Strauss-Kahn’s lawyers.
But many of the details of what has been uncovered by the NYPD and the office of the Manhattan district attorney, Cyrus R. Vance Jr., which is prosecuting the case, have been closely held, and officials in both offices would not confirm or deny the account’s general outlines or the details.
The lunch, which lasted about ninety minutes, one of Mr. Strauss-Kahn’s lawyers said at his bail hearing, could figure prominently in the case, which has already cost him his post as the managing director of the International Monetary Fund and his status as a leading contender for the French presidency.
Indeed, if one of several security cameras visible in the large restaurant captured the pair, the images of father and daughter in McCormick & Schmick's seafood restaurant, less than an hour after the encounter with the housekeeper, could serve as powerful circumstantial evidence. It could bolster the defense case if they laugh or appear to share a leisurely meal; it could support the prosecution if it shows the sixty-year-old white-haired Frenchman looking distracted or upset.
Mr. Strauss-Kahn’s lawyers, William W. Taylor III and Benjamin Brafman, have sought from prosecutors any video recordings, including anything from the restaurant on West 52nd Street near Avenue of the Americas. (The choice, perhaps incongruous for a man renting a town house listed for $50,000 a month, was made by his daughter, according to the person familiar with the defense inquiry.)
But it is unclear whether the police and prosecutors have any recordings from the restaurant, and, if they do, what they show. Paul J. Browne, the Police Department’s chief spokesman, and Erin M. Duggan, the chief spokeswoman for the district attorney’s office, would not discuss the issue. Tori Harms, a spokeswoman for the restaurant company, which is based in Portland, Oregon, would not answer questions about the matter, saying in a statement: “it is always our policy to cooperate fully with law enforcement authorities when matters or investigations involve our company” and that the company does not “discuss publicly details about any restaurant guest without his or her consent”.
What seems clear, however, is that along with the details of the encounter on 14 May— prosecutors say Mr. Strauss-Kahn ripped the woman’s panty hose, tried to rape her and forced her to perform oral sex, while his lawyers say there is no evidence of force and suggest that any sex was consensual— both sides have focused on events later that day.
At issue are Mr. Strauss-Kahn’s movements in the hours between the incident, which prosecutors say occurred around noon, and when police detectives from the Port Authority of New York and New Jersey lured him from his first-class seat on Air France Flight 23 at 4:40 p.m., minutes before it was to depart Kennedy Airport for Paris.
While few details have been made public, a picture of Mr. Strauss-Kahn’s afternoon has begun to emerge from interviews with people briefed on the defense inquiry and through court records filed in the case. Mr. Strauss-Kahn checked out of his suite at the Sofitel on West 44th Street near Avenue of the Americas, at 12:28 p.m., according to a bail application filed on his behalf.
One of the prosecutors in the case, John A. McConnell, said at Mr. Strauss-Kahn’s arraignment on 16 May that video recordings from a security camera in the hotel lobby that show him leaving “minutes after the incident” depict what “appears to be a man in a hurry”. Mr. Brafman, however, said then that Mr. Strauss-Kahn was rushing to his luncheon appointment.
Mr. Strauss-Kahn traveled from the hotel by taxi, bringing along his two small dark-colored bags, one an overnight case and the other a briefcase, according to the person briefed on the defense investigation. Detoured by the street fair, traffic moved slowly, the person said. It took him fifteen minutes to cover the eight blocks, arriving at roughly 12:45 p.m., according to the bail application. He and his daughter, the person who was briefed said, sat in one of several booths at the restaurant, which have dark green leather seat cushions and plush chenille backs and look out onto West 52nd Street.
At Mr. Strauss-Kahn’s bail hearing on 19 May, another of his lawyers, Mr. Taylor, called the meal “a leisurely lunch with a member of his family.” At the end of the meal, according to the person, father and daughter were joined briefly by her boyfriend; the meeting, the person said, was the reason for Mr. Strauss-Kahn’s visit to New York. Mr. Strauss-Kahn paid for lunch with his credit card, the person said. He was back in another taxi and headed to Kennedy Airport at 2:15 p.m., Mr. Taylor said at the 19 May hearing.
On his way to the airport, he apparently realized he had lost track of one of the several phones he usually carried, and he used another to dial his daughter, the person said. The missing phone was the one issued by the IMF and he was apparently concerned about sensitive material on the device, the person said. He asked his daughter to return to the restaurant to look for it, the person said, which she did. She and the waitress who had served them lunch were later seen crawling on the floor, looking under the table, another person with knowledge of the matter said. But they had no luck, and he eventually called the Sofitel at 3:29 p.m. to say he had left his phone in his suite, according to court papers filed by the prosecution. The police were already there, responding to the reports of the attack, and they listened in on the call, coaching a hotel employee to say the hotel would look for the phone in his room, according to the court papers. During a second call, at 3:42 p.m., Mr. Strauss-Kahn was told the hotel employee would bring his phone to him. In a third call, at 4:03 p.m., he asked when the hotel employee would arrive. He had arrived at Kennedy around 3 p.m., and a security camera there had captured a man that may have been him arriving at the curbside drop-off, according to a person with knowledge of his movements at the airport. Air France security cameras photographed him being escorted through the terminal by two Air France employees, and being shepherded through airport security screening and to the airline’s first-class lounge by one of the Air France employees, the person said. Any Air France recordings are also being sought by the defense, according to their discovery demand, a document that seeks evidence the prosecution may possess, but the person said that the airline had told investigators that additional recordings made by a security camera in the lounge, where he was awaiting the return of his phone, had been recorded over and were not available. It was apparently his effort to get the phone that ultimately resulted in his capture, according to the papers filed by the prosecution. The papers suggest that Mr. Strauss-Kahn left his seat and came to the doorway of the jetliner moments before the plane was to leave because he believed the two men there were hotel employees bringing him his phone. As he approached the men on the Gate 4 jetway at 4:40 p.m., he asked them, apparently before either had a chance to speak, “Do you have my cellphone?”, according to the document.
But the men, Detectives Terry Ng and Dewan Maharaj of the Port Authority of New York and New Jersey Police Department, did not, and the document included the following exchange.
“Mr. Dominique Strauss-Kahn?” Detective Maharaj asked.
“Yes,” he replied.
“We would like you to come with us,” the detective said.

Rico says that this guy having no visible reaction would be consistent with the sort of sociopath he's accused of being, rather than the opposite...
