This is absolutely right, leaking this information is wrong.
If it wasn't leaked then how do we know about it?
SECRECY OF GRAND JURY PROCEEDINGS
Secrecy as to all grand jury proceedings is of the utmost importance.
This includes not only the actions upon an indictment or a presentment but even the fact that any such matter was considered, or any witness was called. It is only in this manner that the grand jurors themselves can be protected from pressure by persons who may be involved by the action of the grand jury. Secrecy also is the only protection that a witness may have before a grand jury, which will protect the witness from being tampered with or intimidated before testifying at the trial. Further, secrecy may prevent one under indictment, or subject to indictment, from escaping while the issue of indictment is under consideration. It also should be remembered that secrecy may encourage witnesses to give the grand jury frankly and candidly any knowledge they may have concerning crime or corruption. Lastly, and of equal importance to all other consideration of secrecy, is the fact that an innocent person who has been subjected to a charge but not indicted should be protected from the embarrassment and disgrace attendant upon the making of a charge before a grand jury.
The pledge of secrecy is paramount. It also is permanent.
A grand juror will not communicate to family, friends, associates, or anyone concerning any matter that takes place in the grand jury room. The only time this veil of secrecy may be lifted is by order of the court after a full hearing, and then only in exceptional cases.
