Edward Jay Epstein believes so:
At 1:31—one hour after Diallo had first told a supervisor that she had been assaulted by the client in the presidential suite—Adrian Branch placed a 911 call to the police. Less than two minutes later, the footage from the two surveillance cameras shows [Brian Yearwood, the hotel’s chief engineer] and an unidentified man walking from the security office to an adjacent area. This is the same unidentified man who had accompanied Diallo to the security office at 12:52 PM. There, the two men high-five each other, clap their hands, and do what looks like an extraordinary dance of celebration that lasts for three minutes. They are then shown standing by the service door leading to 45th Street—apparently waiting for the police to arrive—where they are joined at 2:04PM by Florian Schutz, the hotel manager.
The hotel is denying any grand conspiracy:
The Sofitel specifically challenged the article’s assertion that two of its employees were caught on video celebrating for three minutes. “In fact, the incident in question lasted only 8 seconds and both employees categorically deny this exchange had anything to do with Mr. Strauss-Kahn,” the hotel’s statement said.
A source familiar with the hotel's evidence, who spoke only on condition of anonymity, told The Daily Beast that all security-video footage was reviewed again this weekend and that two employees were questioned in connection with the Review article. The two employees said they couldn’t recall the exact reason for their fleeting celebratory behavior but that they believed it may have involved sports, which they frequently talked about, the source said.
