§ 327 Jury to retire.

Once the grand jury has been chosen and sworn in, they don't discuss the case in the courtroom. Instead, they go to a private room by themselves. There, away from the public and other officials, they begin looking into the crimes that fall under their authority to investigate.

This privacy is a key part of how grand juries work. It lets jurors talk freely and review evidence without outside pressure or influence. The private setting also protects the people being investigated, since not every inquiry leads to formal charges, and keeping things confidential prevents unnecessary harm to someone's reputation if the jury decides not to indict.
