It perhaps wasn't the best day to inadvertently dress as a Mafia hit man and go to the library - Col. Williams was in court across the street and security was very tight; the press was there in force.
Through the main entrance of the court building was a metal detector to get to the corridor to the court room where Williams was testifying. Oddly, the rear entrance didn't have one and it was possible to walk through the corridor where the court room was and exit via the entrance where the metal detector was.
The press was there in full force - all national networks had satellite vans there. At one point a lady pushing a baby carriage walked along the sidewalk was stormed by reporters who circled her.
