The challenges of preparing a federal grand jury witness can be complex and frightening. The grand jury’s power, its secrecy and the roles of counsel all make for a dangerous environment. The rules and procedures surrounding the grand jury may vary significantly from one jurisdiction to another. It is a very special type of proceeding.
