The prosecutor does not need have to let you testify in a grand jury proceeding nor can I imagine an instance in which they would want to. The purpose of the grand jury is to make sure the government's case isn't total nonsense, not to establish guilt or innocence. Therefore, the government presents its evidence to the grand jury and the grand jury decides whether there is enough evidence against you to move forward with a charge. No defense is presented at this stage. If the grand jury does return an indictment charging you with a crime, hire a defense attorney immediately.
Answers provided by attorney Matt Williams to questions on Avvo DO NOT form an attorney client relationship. Mr. Williams is available to represent persons charged with crimes in Ohio for a fee. Only after Mr. Williams is retained, or agrees to discuss a matter privately, shall Mr. Williams be deemed your attorney. Mr. Williams answers questions on Avvo only to provide general advice based upon the limited information in the question.
Anyone being investigated by federal authorities, or indicted by federal authorities, should be working with retained or appointed counsel as soon as possible. The attorney can advise about the individual's rights and options, as the investigation proceeds, and also advise about limitations on those options (such as the unfortunate reality that prosecutors have broad discretion in conducting grand jury investigations). General information in a public discussion forum is not a substitute for confidential advice from an attorney familiar with the specific facts of the case.
