I have posted this on several threads and I am just going to put as much info as I can here to clarify because I noticed that many people seem to still think that since the FBG is not LE, she is not required to give LE any information. She can plead the fifth for anything that could incriminate her of being involved in the crime and she could plead the fifth on misprision, but if she is seeking immunity, she wants to talk. They even mentioned it on NG last night.
NO MATTER WHO YOU ARE OR WHAT YOUR JOB (Not yelling, just emphasizing) if you have information on a crime that has been committed, you MUST report it to the proper authorities as soon as you are physically able. If you do not, you are guilty of Misprision of a Felony.
U.S. Code, Title 18, Part I, Chapter 1, Section 4
Misprision of a Felony
Whoever, having knowledge of the actual commission of a felony cognizable by a court of the United States, conceals and does not as soon as possible make known the same to some judge or other person in civil or military authority under the United States, shall be fined under this title or imprisoned not more than three years, or both.

MISPRISION OF FELONY - Whoever, having knowledge of the actual commission of a felony cognizable by a court of the U.S., conceals and does not as soon as possible make known the same to some judge or other person in civil or military authority under the U.S. 18 USC
Misprision of felony, is the like concealment of felony, without giving any degree of maintenance to the felon for if any aid be given him, the party becomes an accessory after the fact.
