What does Cole notice about Jonathan Green's office when he meets him and Truly about his Rossi report?

Green's offices are on Sunset Boulevard, not Beverly Hills or Century City like other prominent lawyers. The building is ornate and older. It has state-of-the-art security equipment, which is kept out of the public eye. As Elvis pulls into the parking garage, a man in a red blazer meets him to open a gate. Elvis notices he had a gun. Additional security is in the lobby and on the elevator. Elvis is taken aback by the amount of security. He is told that the security was necessary because some of Jonathan Green's cases are unpopular.
