Grand jury proceedings take place largely in secret, meaning the public will likely learn little about what the jurors are hearing. If or when the prosecutors think there’s cause for an indictment, they will ask the grand jury to vote. A federal grand jury doesn’t need to reach a unanimous decision. Grand juries differ from trial juries, or petit juries, in a few other substantive ways. “Grand juries line ’em up, file ’em in, sit ’em down and off you go, because grand juries often hear all manner of cases,” said Andrew Leipold, a professor at the University of Illinois College of Law and an expert in grand juries.
