You will be informed of a "Bill" or "No Bill." Trust me, you will be informed.

No the two are synonymous. A "true bill of indictment" is the agreement of a grand jury that probable cause does exist to order a defendant to stand trial on the charges in the indictment. When this occurs, the grand jury is said to have "indicted" the defendant.

It means that charges are dropped by a Grand Jury and the persons record is cleared.

.... it is known as a 'True Bill of Indictment.'

Indictment by a grand jury is the manner in which the government charges individuals with commission of a crime. The prosecutor presents proofs before the members of the Grand Jury to convince them that sufficient evidence exists to charge an individual with a crime. If the Grand Jury agrees that the individual should be so charged it issues a written statement making the charges. The statement is called an indictment.

It is called an "Indictment" or sometimes, "A True Bill."
