Sorry to drag the Brown case into this thread but I'm not gonna try to ask honest questions in that other trainwreck of a thread (although I'm enjoying YF23, HF, even Todd Andrews in there).
So according to some sources it's well over 99% of grand juries return verdicts of probable cause. Prosecutor doesn't have to present all evidence, controls the narrative etc. It seems (and correct me if I'm wrong) that a grand jury proceeding is simply meant to rubberstamp what the prosecutor already intends to do.
Yet it also seems like a prosecutor can bring charges against a suspect and there can be a criminal trial without a grand jury. Is this the case? I understand why they convened a grand jury for the Brown case in this context, but if the prosecutor has the power to indict a suspect and bring them to trial then why would they ever use a grand jury?
Tangentially, was this grand jury process extraordinary in its scope, length, and level of detail of evidence presentation?
1. Read my posted above yours. I think I answered some of your questions that you asked again. Nonetheless, never mind, I'll just answer them again.
2. Yes, it is incredibly rare for a prosecutor to not obtain at least one charge amounting to a true bill when a case is presented to a grand jury.
3. While the prosecutor definitely controls the narrative (in fact, in some jurisdictions, the defendant or the defendant's attorney may not even be permitted to be present) and in doing so can ask leading questions or witnesses (a distinct advantage), generally a prosecutor must present all relevant evidence - whether inculpatory or exculpatory. Essentially, a GJ is really supposed to hear everything the state's got whether good, bad, or ugly.
4. All that said, it's not intended to be a rubber stamp. A GJ is supposed to be a check by the populace against the executive as it permits random community members to act as a sort of gatekeeper to the state's cases. However, the burden of proof (probable cause) is a low standard. Additionally, good prosecutorial discretion means that a prosecutor is likely only taking "good" cases to the GJ where the prosecutor believes he already has PC.
5. In many jurisdictions, it is possible to bring a case forward without going to the GJ. For example, at least in my jurisdiction, any misdemeanor charge can be brought by a simple complaint. Additionally, in lieu of going to a GJ on a felony, a prosecutor can have the case heard by a judge/Justice of the Peace in the form of a mini-trial whereby the judge plays the role of GJ. However, a Defendant MUST be present at this hearing and will have counsel who has the right to cross-examine witnesses (making this generally not the preferred method by the state). Additionally a Defendant can waive the right to have the issue of PC heard. This is usually done for some benefit like a reduction in bond or a guaranteed offer to be taken later.
6. Yes, this GJ proceeding was very long and drawn out compared to the norm.
