If you're familiar with the book, then you know that there are, as Irina Turgenyev was kind enough to confide to you, some members of the crew who did have agendas. In this game, you are the usual Kleptomaniac Hero. So you are meant to take everything that isn't nailed down. However, only in rare circumstances are you actually allowed to drop things or put them back where you found them. In some instances where you cant, you really should be able to since you are finding confidential messages between Sabatini and Brown or Heilmann and Tabori/Yamanaka. You are essentially invading people's privacy by looking in their lockers, the exception being Wakefield who explicitly directs you to his locker to find Puck. Nothing ever comes of it during the game, however, which is strange in itself, as one of the characters who Turgenyev heavily suspects, namely Sabatini, actually asks you do her a favor and go into their personal locker to bring them him/her a desired item.
